Fishing Line??. Progress since Review. Letter of intent from BNL to contract for engineering on VTX mechanics/integration at LANL by end of week Not the same as the contract for HYTEC Setting up capital equipment account w/ BNL Chem. Dept. Pretty picture from LANL.

Progress since Review • Letter of intent from BNL to contract for engineering on VTX mechanics/integration at LANL by end of week • Not the same as the contract for HYTEC • Setting up capital equipment account w/ BNL Chem. Dept. Pretty picture from LANL
Items in Craig’s Core Dump • Mechanical interference needs work • Need that LOI • Need requirements, i.e., parameter book • Building Si spec sheet • Need more info on mechanical development, design prototype • Presumably to be done by HYTEC • Cross-institution visits • Plan to go to LANL
Items in Craig’s Core Dump • Power supplies a gap at the moment • Grounding and shielding needs more effort • Where do fibers go after IR? racks 3m away • Temperature control: 7o plan • How does noise increase? • Efficiency of cooling system? • Humidity control at BNL? • In the IR or in the cleanroom? • Radiation requirements (mentioned twice)
Items in Craig’s Core Dump • Assembly issues: • Layout specs for alignment of sensor to sensor • Missing material costs of assembly jigs for strips • Measuring machine for assembly? • How closely are ladders packed • When is alignment in final assembly? • Test/assemble/test in mounting ladders on VTX
Items in Craig’s Core Dump • Scope of project ends when VTX is ready for installation • Leave installation costs off the budget • Installation costs = operations + extra manpower • 1 week for installation? • How much time for commissioning? • Consider beam test of a ladder • PHOBOS did this • Plan B if we don’t make Run-8, partial installation?
