16 16 Status of MB4 Production Preparation Sez. di Torino 2 nd iron cast table will be delivered in Sette Comuni on 17 th June. Delivered and aligned Work area enlargement approved by director, installation starts at the beginning of July. Time estimated for completion of infrastructure work (crane extension, air conditioning system upgrade, final cleaning) 2 months. Begin work end July, expected to be finished by end September Plotters: driver cabinets cabled and ready. Only missing part are the beam supports. Mimmo, back from China for MB4 support commissioning, will finish the drawings in July. Parts will be manufactured in September. BUT Mimmo: designed details for MB4 supports insertion done in July but was not planned; presently working on gas system (first 2 weeks of Sept.)  NOT working on MB4. Qutlook: will have start contract w/ integration on Nov. 1 st and work on beam supports until end of Sept. Will start working on I-beams tool drawings in Oct. All other parts have been delivered. Plotter beams ready to be sent to CINEL for milling. Done in July. Glueing machine under test to check functionality for 15mt long pipes and possibility of glue dispenser splitting. One driver lost during set-up, replacement ordered. Tooling: I-beam tooling to be designed starting from September. See above

17 17 Status of MB4 Production Preparation Sez. di Torino MB4 HV and FE frame cabling: 2 electronicians will start to work with us after 8 th july, they will go to Legnaro on 16 July to learn how to start SL frame cabling work. Frames already in Torino ready to be machined. Done Frame cabling will start beginning of September. Preparing area, tools. Silvia collecting docs etc., waiting for material (3 profiles) from CINEL, Madrid (1, end of September); Electronicians will go to Padova, collect cables, connectors etc., more training. Start work in Torino. Schedule: within the present schedule we are expected to provide a first SL by the end of the year. Two months delay in production preparation due to integration work on HV cable length and MB4 support commissioning test in Bejing (Mimmo) -> no MB4 SL before the end of the year. CONFIRMED

18 18 Chamber Installation Scenario in v33 42 ch/wheel in SX in v ch./wheel in SX Installation crew of 4 technicians from home Institutions plus crane operators Installation rate of one chamber/day at start-up plateau at 8 chambers/week One wheel (10 Sectors) = 42 Chambers in 5 weeks YB 0 & YB-1,Sectors 8-9 September-December 2003 ( ch.)  YB+2 January-February 2004 (42 ch.)  YB-2 Sectors 8-9 March 2004 ( 8 ch.)  YB+1 September 2004 YB-1 November 2004 (begin) (42 +?)  YB -1 YB -2 April-June 2005 (68 - ?) 10 Sectors (40 Chambers) are installed in UX5 starting September 2005 (~10 weeks to complete). for Alignment/Magnet Test

19 19 Installation Tools Some tooling is still needed for full scale installation: Transport frames for DT+RPC (CIEMAT). Ancillary tools for cradle rotation (Padova). Construction of a larger cradle for MB4. In addition we will rely on existing SX5 equipment: Cherry pickers, movable platforms … Refurbished L3 scissor lift. Tooling costs are within cost book estimates.

23 23 Last shipment of chambers from CIEMAT to CERN April 2002 Currently 12 ch. From CIEMAT stored at ISR LNL and Aachen will ship 8 ch. each in Oct./Nov Delay due to the gluing of RPC Pads at home.

24 24 Chamber Preparation DT and RPC chambers are sent to the ISR from the assembly centers fully tested Acceptance tests: HV, Leak- rate,noise, cosmics DT alignment calibration DT cabling+services DT assembly with RPCs Storage in transport fixture

25 25 Chambers stored and tested at ISR Hall

26 26 ISR: Standard work: accept/store chambers gas tightness/HV/noise test repair alignment long term HV test (1~3 months) insert/test minicrates cooling test couple to RPC (cooling test) Non standard : glue RPC Pads to CIEMAT ch. (from now to July 03) insert and finish HV cables (4 HV connectors/DT in ~ 80 ch at 4ch/week then done in the labs) complete gas and cooling piping (~ 60 ch. at 3 ch/day then done in the labs)

27 27 Presenze gruppi DT INFN ad ISR durante 2003 Bologna 2 persone X 6 mesi = 12 m/u Padova 2 persone X 6 mesi = 12 m/u Torino 2 persone X 2 mesi = 4 m/u L’idea e’ di avere 4~ persone per I due mesi di installazione E di due persone per 8 mesi per attivita’ di completamento Ricezione/stoccaggio e test. Altre 3 persone saranno inviate Da Aachen e CIEMAT. Inoltre Pd e Bo chiedono di mantenere un fisico per 12 mesi Complessivamente e che questa persona sia conteggiata al di fuori dei 2.5 m/fte usuali. E’ chiaro che RPC devono essere coinvolti nell’operazione E mantenere anch’essi qualcuno in permanenza,quando e in Quanti dipendera’ dagli sviluppi della loro costruzione

28 Transport to CERN 2 - Test at ISR 3 - Alignment calibration 4 - Installation of RPC(s) 5 - Transport to P5 6 - Test at P5 7 - Insertion in YB 8 - Test in YB (gas,cooling,HV) Several ancillary tools are needed that are under design or construction Extension rails for DT+RPC DT+RPC package Insertion test : 1 MB2 ch in july-septemb 02 Sector insertion : before the end of 2002

36 36 Further Installation Tests Sector Test: Install MB1, MB2, MB3 complete with cables and services. Installation of a minicrate ( trigger,readout and control electronics) on a chamber already installed. MB2 minicrate prototype with readout electronics under test in CIEMAT


38 38  Madrid reports there are enough ROB-128 (with HPTDC v 1.1) to equip two full minicrates.  Final ROB-128 design will be verified in short time and 10 more boards will be available. Assembly of boards with final HPTDC will not start until late this year.  The company designing ROS-8 prototype PCB has reported routing problems and is delayed. The final board for MC operation is expected by September. Preliminary operation has been described.  Two MB1 minicrate mechanics are ready at the moment, two MB2 are in process. HPTDC/Cern/Mic was resubmitted in September to include small corrections mainly to the Voltage regulator. Using the HPTDC from the previous engineering run CIEMAT produced several Rout Boards

The Minicrates need also Control&Server Board.

43 43 Control and server boards They sit in the MINICRATES of which they control all the functionalities These are two boards :the server is piggy backed on the Control. The Control board was slightly modified after the system test to house some buffers and to accept new connectors. The design of the new PCB is going on and will be finished by end september. The Server part is complete and ready to be produced. The funding for both is allocated in the 2002 /2003 And first orders will be placed soon. However the Control must Wait for the final TTC/RX. We hope to have by october the Pin out in order to complete the PCB. A proto with the old scheme is in any case needed for the MINIC. Test at the end of 2002
