ITEM Components Description Questions STATUS Date Complete
Module
Frame Machine in-house. G10 seems obvious choice. Is exact thickness of G10 important? Do we want two different designs for single vs. double-sided? How is module fastened to vessel? Not done. 6/1/01
MCM
Physical Hybrid Actual PCB that components are mounted on Design is complete, bids are actively being sought out. 6/1/01
ASICS Front-end Readout Chip, Controller Chip Have limited supply, new chips are being acquired. Done
Components Connectors and passive circuitry Components are being acquired 5/25/01
Detectors Silicon microstrip detectors. We dont know if the double-sided detector is functional. Patrick is testing the detectors presently 5/25/01

CABLE 3M twisted pair cable and connectors 30 pin connectors, 30 wires, 29 wires used. Is there agreement on the mixed serial/parallel method? Not built. 7/1/01
DAQ Repeater Card(?), DAQ card Sends commands to module and reads out data. We should use the same DAQ eventually, to head off compatibility problems. SCIPP currently uses a custom DAQ. 7/1/01

Minimizing Errors

• Mechanical errors
• Spatial conflict
• Out-gassing
• Pressure(explosion/implosion)
• Data errors
• Use Identical DAQ
• Test MCM with charge injection

Schedule
ITEM Components Description Date Complete
Module
Frame Have G10. Need final dimensions. Will machine in-house. Lead time is 2 weeks. 6/1/01
MCM
-Physical Hybrid Design complete. Seeking bids, construction lead time is 2 weeks. 6/1/01
-ASICS Have all front-end readout chips. Have some controller chips, are acquiring more to replenish supply. Done
-Components Need to order passive components and connectors. Lead time is on the order of 2 weeks. 5/10/01
Detectors Have detectors, and have tested single-sided detectors. Need to check double-sided to see if able to be used. 5/20/01
Module Completion 7/15/01
CABLE 3M twisted pair cable and connectors Connectors need to be bought. If cable can be found with shorter intervals of twisted between ribbon sections it would be good. Lead time is 1 week. 7/1/01
DAQ Repeater Card(?), DAQ card SCIPP eventually needs to buy a DAQ identical to LLUs. 7/1/01
Single-sided SMD Telescope Completion Date 7/20/01
