Minutes of feedthrough meeting of 20 November, 2000.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Present: PB, Pof, GV, AD, TH, MLenc, RKK, MGF, ML

*) Milestones

	- ft02 cold tests were done.  Electrical tests
	  were all ok, but vacuum tests were ambiguous,
	  indicating the possibility of a small leak
	  between the cold box and the bellows volume.
	  This signal could also be seen if there was
	  helium leaking into the air and entering the
	  leak checker via the pump.  The cold test station
	  will be leak checked and debugged this week, and 
	  the cold vacuum tests on ft02 redone. 

	- BNL has received 33 pincarriers, all of which
	  have tested ok.  Tom Muller reported last week 
	  that HCC might be able to get a third machine into 
	  production by winter or early spring so that the 
	  production rate could be increased to 25 units per 
	  week.  Tom reported this week, however, that
	  Glasseal/HCC have recently discovered side-wall
	  leaks in some of the 8-row pincarriers made with HCC
	  supplied 304-L steel, which all future pincarriers
	  are to be made with.  Glasseal has asked that
	  two options be considered, the first being that
	  they switch to Carpenter Project 70 Stainless
	  Type 316L material.  The second option to consider
	  is to increase the side-wall thickness.  Either of
	  these options might require lengthy new R&D and
	  so are not particularly attractive.  Michel will
	  send an email to Tom expressing our postion.

	- The 40 LV VacuumCables have all been measured
	  with Phred and verified that each line of each
	  cable is the correct gauge.

*) Mark presented some drawings of possible scenarios for
   the shipping crates, particularly the `one feedthrough
   per crate' scenario.  We need to check how tightly the
   pigtail bundle can be bent without risk of damage.  We also
   need to check that all electrical and vacuum tests can
   be carried out with the feedthrough still in the crate.
