Minutes of feedthrough meeting of 01 October, 2001. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Present: Pof, GV, AD, FH, PB, JL, RKK, ML, ASD *) Milestones - The cold cycles for the two 7-row and one 8-row 'spare' pincarriers received 26 September have been finished. *) The Vacuum and Electrical test equipment for use at CERN will be shipped out this week. *) Final electrical tests on ft15 (our last HEC for ECC) will be finished this week, and cabling of ft16 (the ECC FCAL) will continue. *) The pincarrier (S/N 5000 0291 271 0132) which showed a leak on early tests has now undergone five further cold cycles beyond the normal three, with no sign of the leak in any leak test conducted after each cycle. It will be used in a warm flange if no other pincarrier is available. *) While cabling ft16 last week, pins were bent in three different pincarriers, which resulted in one pin (in a 7-row pc) breaking while attempting to straighten it, and another pin (in an 8-row pc) developing a leak. Both pincarriers have been machined out of the flange, leaving ample weld lip, and replaced with new pincarriers. *) Our current stock of available 'good' pincarriers is: - three 7-row (includes the 'pseudo' leaker S/N 5000 0291 271 0132) - four 8-row Failed or broken pincarriers are: - three 7-row (one on which we broke a pin, and two of which have gold plating on a glass bead which need to be returned to Glasseal) - one 8-row (developed a leak after bending a pin) Two of the good 7-row (not including S/N 5000 0291 271 0132) and two of the good 8-row will be used to weld the cold flange for ft17 (the last Special for ECC) later this week. *) 24 pincarriers were shipped from Glasseal on Friday 28 September. We should probably receive them early by next week. *) Pof, PB, JL, and ML will be at CERN for LARG week; pof will give a short presentation at the C&C General meeting at 13:30 on Monday, with emphasis on the lack of sufficient pincarriers. Other meetings of note are the Integration and Installation meeting at 09:00 on Thursday, and the special Filter Box meeting at 09:00 on Wednesday. Agenda for next week (AD to chair): ^^^^^^^^^^^^^^^^^^^^^ - Milestones - progress on the FCAL ft - plans for the week - AOB
