Crate Design Status
24 Slot “J-Crate” produced.
Few problems to clear up
Complicated surface treatment (electrical vs thermal requirements) under review at CGS.
Slots for “EMI” plates very difficult to machine. Drop for next version of crates – wait for QM results.
Drawings for U, UG Crates could be ready “soon”.

19. Drawings started based on FlightDesign Tables for TPD.
xPD Design
Drawings started based on FlightDesign Tables for TPD.
Complete set reviewable by 1 Sept.
Need input from xPD responsibles
(btw – who is that for UPD?).

20. Crate and xPD production:
CSIST has agreed to produce:
Mechanics: 4 U-Crates + 4 UPDs
(nothing for UG, UGPD)

21. RWTH has agreed to produce:
Crate & xPD Production
RWTH has agreed to produce:
2 U-Crates (“QM1”, =EM?)
0? UPD
3? UG-Crates (EM=QM, FM, FS?)
3? UGPD (ditto).
Crate Production (1 U & 1 UG)
could start Sep ’02 ?
(assume number of slots fixed)
xPD Production (0? UPD & 1 UGPD)
Could start Q4 ’02 ?
(assuming contents fixed)
