LAT Engineering Meeting Issues & ConcernsIssues & Concerns
• Timely and Appropriate review of Documents
• CAL Interface (CAL-LAT IDD LAT-DS-00233 Rev 07)
– 4 weeks to receive comments.
• ACD Interface (ACD-LAT IDD LAT-DS-00309 Rev 04)
– Check print sent out for review, 9/22, waiting for feedback
• MLI Blanket Design
– Conceptual design still in review by Spectrum
– The only feed back received since 9/7/04 is a request for additional drawing views on 10/28
– Note the additional work to provide views was not planned until conceptual design approval was given.
• Instrumentation
– Detail design of cabling over 50% complete, cooperation between subsystems is required
– Issues still open from last month• Instrumentation Termination Bracket design definition• Specific locations and mounting methods have been defined, need to be reviewed• Still need detail harness definition for accelerometers
