3
PDR Requirements

• The meetings this week were extremely productive
• Most of the PDR data has been received or has
  been promised within one week

4
SRD

• Note at PDR that the design of the SRD is
  dependent upon the successful results from the
  PSRD flight

5
TRD

• Interface Set

6
TRD Gas Resupply System
7
ACC

• Interface Set

8
RICH

• Load Factors to be modified for next iteration
• Design to change to accommodate larger hole size
  (ECAL larger than RICH hole)
• Mass Simulator will be provide to LM
• Need to assess shaterable materials (smaller than
  .25 lbs and enclosed
• P. Apollonia to provide bolt analysis and fail
  safe analysis
• P. Apollonia to provide parts list vs. margin
  list
• LM to perform MMOD assessment and provide debris
  shield for mirror (reflector)

9
TOF

• Interface Set

10
Tracker

• LM to change tolerance of inner cylinder to 1/-0
  mm

14
Electronics Crates

• Agreed to approximate orientation and arrangement
  of crate racks (LM to propose interface)

15
Cryomagnet

• All additional items covered in meeting and
  Action Items

16
Cryomagnet, Cont.

• Extremely Productive Meeting
• Action Items
• OI to provide Design Report ASAP
• LM to assess fracture issues
• OI to provide presentation and drawings today
• S. Harrison will provide updated cryogenic
  schematic by May 17
• LM will include 10 bolt pattern inside the
  support rings with a 6 inch spacing
• S. Harrison will perform several new vent
  analyses for new arrangement
• S. Harrison will find test data to correlate
  analysis method (may have to perform test to get
  the data - TBD)
• OI will review LM Vacuum Case drawings to assess
  port locations
• OI will send sample bolts to LM for JSC Fastener
  Integrity Program
• OI will send test data on strap tests
• OI to work with LM on all welds including
  bi-metallic welds
• LM to look into possibility of sending OI an
  Orbital Welder
• OI will send LM information on rotating the
  Vacuum Case for the close-out weld
