1. SSD Tasks and Costs Howard Matis October 14, 2010 1

2. Boundary Conditions Tasks are 85% completeTasks are 85% complete Schedule is about 30% done – lots of guessesSchedule is about 30% done – lots of guesses Cost not doneCost not done Work done by a novice physicist – Not by an engineerWork done by a novice physicist – Not by an engineer Estimates of time has been optimistic in the pastEstimates of time has been optimistic in the past 2

4. 1.4.1 Mechanics Needed now Needs to be done during OSC design 4

5. Mechanics - Comments Need envelope of ladder cable board soonNeed envelope of ladder cable board soon Most of mechanical work can be done in 3 monthsMost of mechanical work can be done in 3 months Do we need to design brackets before OSC design is finished?Do we need to design brackets before OSC design is finished? Must put in those constraintsMust put in those constraints Engineering support for WBSEngineering support for WBS When will this be doneWhen will this be done SSD Mounting brackets needed before alignmentSSD Mounting brackets needed before alignment 5

8. Ladder - 1 Done 8 The next big thing to do is test!!!

9. Ladder-2 9

10. Ladder-3 10

11. RDO Critical Items 11

12. FPGA Progress FPGAs critical to success of projectFPGAs critical to success of project FPGAs for VME and DAQ/TriggerFPGAs for VME and DAQ/Trigger VME design mostly doneVME design mostly done DAQ/Trigger big questionDAQ/Trigger big question Needs SUBATECH resourcesNeeds SUBATECH resources Have not received a date when this will be completedHave not received a date when this will be completed Need pinouts for RDO Board developmentNeed pinouts for RDO Board development Slave FPGA well underway by MichealSlave FPGA well underway by Micheal RDO board needed to test Ladder BoardRDO board needed to test Ladder Board 12

13. DAQ At least one TCD high priority 13

14. DAQ Comments Using conventional DAQ for STARUsing conventional DAQ for STAR Minimal technical riskMinimal technical risk Resources for this is minimalResources for this is minimal Tonko will do much of itTonko will do much of it Nevertheless, we need to develop diagnostic softwareNevertheless, we need to develop diagnostic software 14

15. Test System 15

16. Test Comments Need to purchase minimal elements of power supply soonNeed to purchase minimal elements of power supply soon As soon as we confirm power requirements of Ladder BoardAs soon as we confirm power requirements of Ladder Board Slow controls needed soonSlow controls needed soon Decide how many systems we needDecide how many systems we need Do we need TCD and how soon can we get it?Do we need TCD and how soon can we get it? 16

17. 1.4.3 - Assembly 17

18. Assembly Comments Where to do testing?Where to do testing? LBNL – requires extra airplane flightLBNL – requires extra airplane flight BNL – can alignment be done thereBNL – can alignment be done there Need to mount carbon elements to SSD laddersNeed to mount carbon elements to SSD ladders LBNL shop can do thatLBNL shop can do that Can BNL do it?Can BNL do it? Who will do the translation from measurements to STAR database?Who will do the translation from measurements to STAR database? 18

19. Infrastructure – 1.4.4 Cables 1.4.4.1Cables 1.4.4.1 Relatively easy to produceRelatively easy to produce Some risk in aluminum cablesSome risk in aluminum cables Should start nowShould start now Need to have concept of patch panels on OFC and ESCNeed to have concept of patch panels on OFC and ESC Pick power supply soon so that can develop slow controlsPick power supply soon so that can develop slow controls Wiener is a good choiceWiener is a good choice Need to start coolingNeed to start cooling Jim is coming backJim is coming back Slow controls big manpower gapSlow controls big manpower gap Get hardwareGet hardware Need person soon (within a year)Need person soon (within a year) 19
