Minutes of feedthrough meeting of 6 November, 2000.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Present: GV, AD, PB, Pof, TH, RL, MLenc, MGF, RKK, MLef

*) Milestones

	- The circuit boards for the flange heater fuse
	  block have arrived.

	- Chris Oram notified us that the irradiation tests
	  for the thermal conduction pads have passed.

	- 98 Vacuum cables will be returned to FCI this week
	  for further testing and repair.  96 had upside down
	  centre spacers, one had no centre spacer, and one
	  had a plastic connector with an over tolerance width.

	- Mark has completed a preliminary drawing for the
	  ambient flange heater.

*) The LV vacuum cables should be tested with Phred to check
   that the wire gauges are all correct.  The resolution of
   the Cirris tester is insufficient for such a check.

*) The ten T51 cables that UVIC ordered directly from Axon
   are to be returned to Axon for electrical testing with
   the Orsay test setup.

*) Horst Brettel has found a suitable backplane connector
   to which wires from a LV warm cable could be soldered.
   One scenario is that the ATI connectors to be attached
   to the warm flange are purchased from Axon with the wires
   attached, and that someone (not us, perhaps Mainz?) then
   solders the wires to the backplane connector.  It should
   be verified that the connector that Horst has chosen has
   the appropriate current carrying capacity.  The wire coating
   must also be chosen carefully; kapton is probably not
   usable out of vacuum due to its flamability.  Perhaps the
   wire type that Mark has found at CERN for the heater wiring
   could be used.

*) Mark is still looking for an appropriate controller and
   power supply for us to conduct tests with the ambient
   flange heaters.  Richard suggested that he contact
   Allain Gonidec for his recommendations.

*) In correspondences between Michel and David Lissauer, David
   recommends that we do not announce to the LARG community 
   that we cannot meet the deadline for the completion of the 
   endcap C feedthroughs.  David remains skeptical of the 
   existing cryostat schedule, and how soon it might be
   ready for the installation of the feedthroughs.

*) Michel has sent a memo to Aboud in response to Aboud's draft
   document entitled "Operations list of signal feed through
   mounting on the end cap cryostats".  Michel's memo seeks
   clarification on a number of "responsibility" issues.

*) FT02 is scheduled to be welded on Tuesday.

*) Construction is underway of a tent in room 021 in which the 
   dye penetrant can be carried out.  This is necessary to 
   prevent particulates that are produced from the dye penetrant
   tests from dirtying the room.

Agenda for next week:
^^^^^^^^^^^^^^^^^^^^^
- Milestones
- Plans for FT02
- Shipping crate ideas 
  (do we want one or two feedthroughs per crate?)
- Temperature controller / power supply update
- AOB
