Peripheral Crate Commissioning Plan
Notes The first 5 crates will be installed in the slice test. See special note below about these crates. These crates will give us a baseline and the experience needed to tweak the plan for the remaining crates. The testing software at B904 and SX5 will be identical. That at B904 will be a sub-set of that used at SX5. The only differences allowed will be to accommodate unavoidable differences in hardware. (The hardware will be as similar as possible, and will progress towards identical sets. ) The software will be based on that used at Rice to certify the first full crate, the DMB testing program at OSU and the single chamber testing at SX5. 8-Nov-19 Peripheral Crate Commissioning Plan

Note on HV & Gas At the writing of this document it is not known how important it will be to the commissioning to have the CSC’s at HV. Clearly having the HV on gives the opportunity to test under the most realistic conditions. The HV on, in turn, requires that gas be flowing for some time. How much gas is available to the commissioning effort, after slice test and long term HV tests, will dictate the commissioning rate. Thus deciding that the commissioning must have the HV on has a very large impact on schedule. There are 60 crates to install and test. At an average of 5 calendar days per crate, for example, the task will take 300 days, or 10 months. At 2 days per crate the task will take 120 days, or 4 months. If we want to test each crate with the CSC’s at HV we need gas flowing. The gas must flow for several days before the HV can be turned on. Nc, the number of chambers with gas flowing equals 9, the number of chambers per crate, times Ng, the number of days gas must flow before HV is turned on, plus Nt, the number of days under test, divided by Nt, the number of days under test. Nc = 9 (Ng + Nt) / Nt Nc = 9 (5+5)/5 = 18 chambers with 5 days of flow and 5 days of test Nc = 9 (5+2)/2 = 33 chambers with 5 days of flow and 2 days of test The gas availability sets the time schedule. Completion in 10 months requires 18 chambers on gas Completion in 4 months requires 33 chambers on gas “A preliminary plan is to provide a working gas for all chambers mounted on the disk +2 (108 chambers) to the end of this year or earlier. After that long term HV tests or a commissioning of 12 peripheral crate will be possible at any time. The next step is disk We will start a gas filling chambers in the end of this year or in the next year. On special request we will provide a working gas mixture to another locations.” Oleg The first 12 crates commissioned will therefore be those on ME+2 and ME+3. During this commissioning we can test with HV both ON and OFF. If it becomes clear that the HV on tests are crucial gas arrangements may then be made. The default plan is to continue without HV 8-Nov-19 Peripheral Crate Commissioning Plan

What is Tested ISR CRB, Crate Regulator Boards, are tested PCMB, Peripheral Crate Monitor Boards, are tested Crate is assembled and checked mechanically B904 LV is applied for the first time to the crate All the on board firmware is brought up to date The communications to all boards in the crate are tested The various boards are tested in a full crate Various functions of the crate + boards + single CSC are tested SX5 Crate is installed for the first time in a rack at SX5 Most B904 tests are repeated The skew clear and other cables are connected permanently and checked for proper connection connectivity and orientation Full crate + full complement of CSC are tested at the same time Can run full set of calibrations (pulses) SX5 HV ON (Is HV needed for this?) Noise for a full crate is seen for the first time 8-Nov-19 Peripheral Crate Commissioning Plan

Overview of Installation & Commissioning
Each peripheral crate will have work done to it and tests conducted on it at 3 locations ISR Crate assembly and CRB testing (10 Series) Assemble crate and affix serial number (Finished), attach grounding bolt, Install BP and check alignment CRB – install hoses, strain relieves and test – underway Install CRB in crate and prep for shipment to B904, storing at ISR until needed at B904 B904 Test (20 Series) Each crate will be tested at B904. There a crate with all boards installed can be tested. Also a single CSC is available, and will be connected to each DMB-TMB/LINK board set in turn for a series of tests. After passing this test the crate and boards will be staged for shipment to SX5. The rate at B904 should proceed more quickly than that at SX5, so many crates may be staged there much of the time. SX5 Commissioning (50 Series) Install at SX5 – into fully prepared racks The board composition of each crate will be the as-tested-at-B904 composition. The crates will be installed one by one, connected and tested in a series of tests. HV ON The gas will have been started on the 9 chambers for a given crate and flushed until the HV can be turned on. The HV ON series of tests will be conducted The temporary services will be moved to the next crate. Meanwhile gas will have been flowing on the next set(s) of chambers. 8-Nov-19 Peripheral Crate Commissioning Plan

Project Scope Scope and environment There are 60 peripheral crates that must be installed on the detector while above ground There are limited services at SX5 (the above ground assembly area) The first 5 peripheral crates will be part of the ‘Slice Test’ and then the ‘Magnet Test’ Slice/Magnet Test - Crates 1-5 > these remain connected while above ground at SX5 Temporary ‘fixed utilities’ => LV for the crates and chambers will be supplied first by commercial supplies. They will later be replace by prototype supplies from preferred vendors which will themselves be tested for magnet field use during the magnet test. Readout a la final system => FO cables are in place on the first disk from the P-crate to the GB, Green Barrack. Later FO for the other disks will be added. These will remain in place until the disks are lowered. Clock & Control a la final system => A TTC crate is in place in the GB to supply clock and trigger control for the slice test. This will remain. Slice Test Software/firmware => ditto Crate Numbers 6 through 60 > these are connected only long enough for the commissioning tests at SX5 Temporary utilities, single crate by single crate => LVPS for a single P-crate and CSC set will be used and moved from place to place. Stand alone readout => A FED crate will be at the test stand and used to read out the data. Stand alone Clock and Control => TTC crate, PC and other hardware will be local and dedicated to this test. Slice Test Software/firmware => 8-Nov-19 Peripheral Crate Commissioning Plan

SX5 Installation Schedule of Peripheral Crates
Magnet Tests NO Access or severely limited Access Lowering YE+3 first Today Start mid-Sep -> 4 months gives mid-Jan-06 10 months gives mid-Jul-06 This is only a straw man schedule, but it illustrates how the project might go for very best case to not so good case. It can also be seen that the magnet test has a large impact on the commissioning schedule. 8-Nov-19 Peripheral Crate Commissioning Plan

Manpower There will be 3 crews with some TBD overlap ISR 1 person full time for CRB testing Others for crate prep B904 1 person to be expert and run tests 2nd/3rd at times to assist in moving crates and board sets SX5 X People to do rack prep 2 people to install crate, hook up utilities, insert boards and connect cables 2 people to help in moving crates into position 2nd/3rd at ~ 1/4 time to analyze data and debug found problems 8-Nov-19 Peripheral Crate Commissioning Plan

Software Needed Software at ISR Control of CRB Readout of CRB to files => Valerii developed a stand alone program as prototype for DCS, this program will continue to be used and further developed Analysis of data files => Excel SS, more to be done Software at B904 Control crate power and read back of voltages => expanded stand alone DCS prototype program from ISR to include boards in crate and CC Remote programming of boards => programs exist but need more refinement, need db of firmware and ‘safe’ library OSU test series => need to be adapted for use here Rice test series => need to be adapted for use here Software at SX5 Control CSC power and read back => prototype DCS program expanded for CSC interface Remote program of CSC on chamber boards => remote programming of boards extended to on chamber boards OSU and Rice test series => adapted to a full set of 9 CSC’s Tests of connectivity to CSC => new software required Test of whether each board/input is connected to the correct CSC on chamber board => new software required Calibration pulsar tests => upgrade existing slice test software Timing measurements => upgrade existing slice test software SX5 series of tests => derived from SX5 single chamber commissioning tests, work already started by Alex Measure and save first set of constants for the crate/CSC combination Measure and understand noise for this full crate system 8-Nov-19 Peripheral Crate Commissioning Plan

Near Term Plans We have four 9U Rev2 Back Planes that can be used as first articles to test ‘the test procedures’, become firmware and software test beds, and/or be added to the slice test. These are the old BP’s that connect to the old TMB’s. There are only 10 old TMB’s presently at CERN. More are needed to run a full set of 4 crates and 36 boards. The near term plans for these crates follows. 8-Nov-19 Peripheral Crate Commissioning Plan

Plan for Rev2 BP P-crates
Rev2 are old 9U BP (we have 4) – Rev3 are starting production now?? 1st Rev2 Crate In slice test now. Rev2 BP but not final P-crate. Swap crate at some TBD date. 2nd Rev2 Crate Waiting for LVPS pair from vendor (due 1st wk Aug) Install LVPS on mockup in ISR, make LV and controls wiring harness Install as 2nd crate at SX5 (Or possibly send to B904 and treat like 3rd crate below.) 3rd Rev2 Crate Wait for 2/3rd sets of LVPS (due mid Aug) Follow full procedure at ISR Move to B904 and use to set up B904 for full procedure Keep at B904? 4th Rev2 Crate Need more LVPS Follow behind 3rd Follow full procedure at ISR and B904 Install at SX5 in slice test 8-Nov-19 Peripheral Crate Commissioning Plan

Detail Slides The following slides contain detailed information on several points 8-Nov-19 Peripheral Crate Commissioning Plan

Outside Connections WWWW …
Which “outside world” connections will be there ? Are the “final” cables going to be there during commissioning? Who and when are those connections going to be made? What => Connected to > Final during commissioning? > who final > when final LV/sense => LVPS > no, some for magnet test > DL, SL, FB > underground PCMB => CanBus(DCS) > no, some for magnet test > DL, SL, FB > above ground? Fiber Optic => LAN(DCS), TTC, FED > no, throw away for magnet test > TY, FG > underground Cooling Water => manifold on disk > yes, but temp to disk > FB, FG > on disk - soon Gas => HV => Other ?? 8-Nov-19 Peripheral Crate Commissioning Plan

Outside Connections Detail
Each crate-CSC will connect to: LV => the LV will originate with AC from the surface and be converted to DC underground. This conversion may take place in a service room or the tower on each disk depending upon which vendor is chosen. Dick Loveless, Sergie Lusin, and I, Fred, are involved in this. The tower connections can be made as soon as a vendor is chosen and materials can be received. The choice will come sometime during the magnet test. CanBus => this is connected to the PCMB on the CRB. It is a copper cable so grounding is a serious concern. This signal probably will originate off the towers and can be daisy chained to each CRB. A maximum of 64 CRB’s can be chained together. There is at present no definitive plan nor schedule for connecting these. Dick, Sergie and I are involved. Local area network => The OSU CC board will connect to a network cable. This will be FO so there are no grounding considerations. The FO bundles will be installed in place when the detector is underground. While above ground all of these are temporary. T.Y. Ling and Frank are working on this. TTC => The P-crate connects to the TTC via FO cables. See LAN above for final fiber situation. The connection is to the TTC crate in the GB for slice test crates, to the test rack for other crates while under test, and to nothing the remainder of the time. FED => The P-crate connects to the FED crate via FO cables so grounding is not a consideration. See LAN above for final fiber situation. The connection is to the TTC crate in the GB for slice test crates, to the test rack for other crates while under test, and to nothing the remainder of the time. Cooling Water HV Gas Other?? 8-Nov-19 Peripheral Crate Commissioning Plan

P-crate IO & GND’s CRB – and all boards LV => Source and return are floating at the source and grounded at the CRB input. Filtering is done on the CRB. Sense => Sense return to PS is floating at the PS and grounded at the CRB. Current on + sense is limited at CRB and filtering is done at the CRB GND => Safety and system ground is from steel of disk to bar in rack to CRB CRB/PCMB (peripheral crate monitor board) LV from CRB/external => CanBus IN/OUT use copper cable. The signal is isolated. But the cable also caries power and gnd which are NOT isolated. This will be daisy chained from PCMB to PCMB. CC (OSU) Ethernet cable => This will be FO DMB Skew clear => connected to CSC. Caries signal and gnd between DMB and CSC. Both ends are grounded locally to safety gnd. CSC control => same as skew clear above Pair of FO to FED crate => FO TMB/Link Skew clear => same as DMB CCB 1 single FO MPC 3 single FO 8-Nov-19 Peripheral Crate Commissioning Plan

Install boards in slots 2-21 – ?? Connect the skew clear cables - ?? 8-Nov-19 Peripheral Crate Commissioning Plan

Crate Numbering Is there a numbering scheme for crates? Can you post it on the web? Yes there is a document that I believe I received from Armando, but may not have. It has no title nor provenance included. From this document I have created an Excel SS that includes all the crates, what chambers connect to which boards in each crate, and the crate names. I will make this public. The peripheral crate names are based on station, trigger sector and for station 1 first or second half of trigger sector VME (station)/(trigger-sector)/{(trigger-sector-half)} VME +1/4/2 => station ME+1, ts 4, 2nd half VME +2/6 => station ME+2, ts 6 Is there a numbering scheme for the boards in the crate? (I assume it is a straightforward slot numbering, but better be sure). Can you post it on the web? Can you post on the web the connection scheme between slots and chambers? Ex: to which chamber is the boards in slot #3 (is it a DMB or a TMB? ) in crate #4 (is this crate on disk +2 or +3 ?) connected? In other words, is there a plan of connection between boards and chambers on paper? The answer is yes, it is in Dick/Armando hands, but I don’t know where to find it. Could it be made public. 8-Nov-19 Peripheral Crate Commissioning Plan

Stan Can we tell if the skew clear cables are connected to the correct chamber, DMB input? That is easy to do. One just reads back the FEB user codes. A data base should (will) exist as to which FEB's are in what position on a chamber. For the TMB skew clear cables one can pulse one FEB at a time and read out the position of the hit in the TMB. For ALCT I am no expert but I assume the user code trick will work here as well. – Stan More difficult but also works. Pulse a single cathode strip in a single plane, then unpack the data and check it is in the right place. We probably should do both. Stan 8-Nov-19 Peripheral Crate Commissioning Plan

ToDo Identify all hardware needed and order long lead time items Missing pieces for B904 Duplicates and new things for test racks at SX5 Start setting up ‘commissioning’ test procedures using slice test crates Collect test lists from Fast Sites Determine what we can do now Determine what to do to get them working Produce schematics of test racks – hardware and software Test install a crate 8-Nov-19 Peripheral Crate Commissioning Plan
