Minutes of feedthrough meeting of March 20, 2000.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Present: MGF, GV, AD, Pof, MLenc, RL, JL, RKK

*) Milestones:

	- The Charpy tests at CERN have passed, easily.

	- The Cuff rings arrived last week from Sicom,
	  and the seal rings arrived this week.  Processing
	  is underway.

	- An 18 GB disk, dedicated for electrical test
	  data, has been installed on STRANGE.

*) There were some inconsistencies between the
   schedule for steel delivery to Glasseal and
   the pincarrier delivery schedule, suggesting
   that Glasseal might have been planning to
   use some of the pieces meant for 8-row pincarriers
   to make 7-row pincarriers.  Terry is to clarify
   this situation.

*) The leak check was shipped to California on monday
   20 March for repair.  Paul will travel to California
   to take a course in leak checker service, and in
   fact will probably end up servicing our leakchecker
   himself.  Pof will look into the possibility of a
   trade-in.

*) Aboud replied regarding our offer of pincarriers and
   `special' flanges at his request.  He would now like
   two 7-row pincarriers rather than one, in addition
   to the two 8-row pincarriers.  Since all of our non-production
   7-row pincarriers are of the gold-plated glasseal type,
   we have only one that we can spare (reluctantly...) since
   we need at least four gold plated pincarriers for our
   electrical tests.  Roy will offer (to sell) three 8-row
   PCT pincarriers and one 7-row glasseal pincarrier.

*) The electrical test setups are progressing and near
   completion.  The time to measure the crosstalk (three
   nearest neighbors) for a vacuum cable with the CAMAC 
   system has been reduced to 6 minutes, plus the time to 
   connect and disconnect the cable.  In addition to the 
   reduced time, the measured results now have a higher 
   resolution.  A similar strategy that gives the improved 
   resolution with quicker measuring time on the CAMAC system
   will now be incorporated into the Tektronix Scope system
   to improve its performance.

*) LabView has an apparent bug, not allowing data transfer
   to a non-local disk.  This makes it impossible to be
   running an electrical test VI on, eg, WINO and writing
   the data onto the 18 GB disk on STRANGE.  Mike R. is looking
   into the problem, and will purchase a LabView upgrade.

*) The HEC cables should be tested for possible ground
   breaks.  Some sort of apparatus, probably utilizing
   the Cirris tester, should be designed for this.

*) Two test setups for the flange heaters will be made,
   one with ~ 90 heaters running at relatively low current
   relative to their rated capacities, and the other with
   ~ 10 heaters running at ~ 95% of their rated power
   capacity.  Cooling of the tests will be necessary, and care
   should be taken that the cooling system cannot fail.  Richard
   was concerned that water cooling might fail and result in
   overheating, and suggested air cooling instead.  He also
   suggested wiring a light bulb in series as a quick indicator
   that the test circuit is still operating.
   
*) Jobs for this week:

	- Process the cuff and seal rings.

	- Continue working on electrical test setups.
