Minutes of feedthrough meeting of 5 June, 2000.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Present: GV, Pof, PB, MLenc, AD, TH

*) Milestones:

	- 32 Seal Rings arrived 31 May.  All have been tested, 31 
	  passed and 1 failed due to a dent near the bellows weld lip.
	  The failed Seal Ring could possibly be repaired if necessary,
	  but we already have more (63) seal rings than required.
	  The 31 `passed' seal rings will be shipped to BOA this
	  week along with the remaining 26 Cuff Rings.

	- Four funnels arrived on 2 June.  However, the radiograph tests
	  of longitudinal weld on the upper funnel tube weld, and the 
	  dye-penetrant tests of all welds were not performed, having 
	  been inadvertantly omitted from the purchase order.  The
          dye-penetrant tests are done locally at SM, however the funnels 
	  must be sent elsewhere for the radiograph tests.  Tom Goldbach
	  of SM will try to find a local (Victoria) source for the 
	  radiograph tests of the four completed funnels so that we can 
	  get them back soon.  The radiograph tests of all other upper
	  funnel tubes will probably be done in Vancouver.

	- FT -1 was removed from the cold-test station.  The modifications
	  to the cold-test station to accept the production glands
	  have been made, but the cold-test station still must be
	  leak checked to ensure all new plumbing is tight.

	- The contact resistance was remeasured for all of the 100
	  vacuum cables.  Offline analysis of the latest measurements
	  will be done this week.

*) After some discussions between RKK, Michel, and Pof, it was decided
   that production of the feedthroughs can proceed without final
   resolution of the HEC baseplane issue, provided that we have
   approval from Pierre Pailler and Allain Gonidec.

*) The remaining 7-row pincarrier material was shipped from Latrobe
   Steel to HCC Machining in California on 9 May.  

*) According the Keith at TRIUMF, the ultrasonic bath *might* be
   back in service by the end of this week.

*) The replacement T-piece glands have not arrived yet from CERN.

*) The eight pincarriers reportedly shipped on 19 May have not arrived.

*) Mark has contacted Ken Sexton at BNL to open discussions regarding
   the heater wiring and thermocouples.

*) It was decided that the thermal pads that go between the warm flange
   and the heater plates can be cut easily enough by hand with a
   scalpel (provided it's not *my* hand...) rather than having a
   special tool made.

*) The RF seal should probably be ordered soon (check with Roy).  
   The price is nominal, estimated at ~ $500 for all 60 pieces.

*) An RFQ should be put out by Mark and Roy for the bellows braces.
   Two quotes should be requested - one for 60*4=240 pieces (enough
   for all feedthroughs) and the other for 45*4=180 pieces (assuming
   that the braces for the first batch of feedthroughs sent to CERN
   can be returned to UVIC before our stock runs out).  My guess is
   that we will probably end up ordering 240 pieces.

*) An RFQ should be put out for the heater plates.  Note that this
   should not be interpreted as suggesting that the heater plate
   design is approved / final. 

*) The lab is in need of a general cleanup this week.
