Minutes of feedthrough meeting of 29 January, 2001.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Present: Pof, PB, GV, AD, RL, MLenc, ML, RKK, MGF, Jan

*) Milestones

	- 159 (exact number still to be confirmed)
	  Vacuum Cables arrived on 23 January.
	  Only 221 Vacuum Cables still to come.

	- A new lab assistant (Fiona Holness) has been
	  hired, and will start work at 08:30 on
	  Tuesday 13 Feb.

*) The Video conference with TIS et al failed due to technical
   problems on Monday 29 January, but was rescheduled for
   Tuesday 30 January at 08:30.  Present at CERN were
   Alberto Desirelli, Pierre Pailler, Stefano Sgobba, and
   Yann Forestier.  Present at UVIC were Terry, Roy, PB,
   and Pof.  In our original weld plan (the plan provided
   to TIS) the upper funnel tube was to be 1.6 mm thick over 
   its entire length.  This design was later modified so
   that the thickness of the upper tube was increased to
   3.4 mm, but reduced to 1.6 mm only at each end where it
   is welded to the funnel base and cold flange.  This design 
   change was implemented so that the `1.6 mm to 3.4 mm' step 
   would act as a mechanical stop to aid in the upper tube to
   funnel base or cold flange weld placement.  TIS had been 
   confused that the 3.4 mm thickness was actually required 
   for the structural integrity, whereas only 1.6 mm is actually
   required.  Once this was explained, Alberto agreed that
   there is no problem with the weld.

   Two requests were made as a result of these discussions:

	- Alberto has requested a revised page 5 part A of
	  the weld plan, such that the upper funnel tube
	  is modified `as built'.  PB will provide this to
	  Alberto during the February LARG week.

	- Pierre requested the dimensional range of radial
	  clearance between the machined upper funnel tube
	  and the funnel base.  Roy responded by email that
	  this clearance range is 0.1 mm -> 0.35 mm.

*) BNL did not respond to Marks email request for their
   shipping crate crate design.  Mark will send another
   email to Tom Muller.

*) Jan will inventory the ATLAS lab computers to check
   which computers need upgrades or replacement.

*) PB will check on the status of the VCR glands while at
   the February LARG week. 

*) Bonnie has checked with Revenue Canada and UVIC Purchasing 
   regarding the license we have which allows us to import
   items without paying duty, as long as those items are 
   re-exported.  According to Revenue Canada, our license has
   only been invoked once, for an Axon purchase of K$33 in
   1998.  This is probably (but not certain) the order of 30 
   production pigtails for one `standard' feedthrough, plus 20 
   pigtail jumpers.  UVIC Purchasing is now looking further
   into the issue of tracking those items for which `the license'
   is invoked.  Also, Bonnie found that there is no `year end'
   paperwork to be generated by us; the only paperwork to be
   filled out will be at the end of the project.

*) Pof will request a letter from Christian Zeitnitz acknowledging
   receipt of the prototype Axon pigtail MD1970/04 that we sent
   him last year.

*) Michel requires cost estimates for all hardware to be purchased
   to conduct vacuum and electrical tests at CERN.  PB will deal
   with the vacuum test costs, and pof will deal with the electrical
   test costs.
