Minutes of feedthrough meeting of February 14, 2000.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Present: AD, MGF, GV, PB, Pof, MLenc, TH, RL, JL

*) Milestones -

	- FT -1 has been installed in the cold station.

	- The rohacell cutting will be completed today.

	- The vacuum cable labels have been ordered and
	  will be delivered directly to FCI/Berg.

	- Two more pincarriers arrived last week.  They
	  have been leak checked (and passed) but not
	  cold cycled.  This might represent the last
	  of the CERN steel.

	- RFQ out for second BNC pulser.

*) Steel Issues: 

	- Roy phoned Ebco about the flange machining, but
	  Ebco had nothing ready yet for inspection.
	  Ebco now expects that machining of some of the warm 
	  and cold flanges will be completed by the end of
	  this week or early next week; Mark will visit Ebco 
	  then to examine the finished flanges.

	- Sicom is now setting up for the final machining
	  of the bolt rings. 

*)	- There has been no information provide by Orsay
	  regarding the pigtail shipment.

*)	- The helium leak checker was showing some signs of
	  possible loss of sensitivity.  Upon invesitigation,
	  it was found that the `line in' settings had
	  somehow been set to 50 Hz!  After restoring it back
	  to 60 Hz and performing a recalibration, the leak
	  checker appears to be behaving again, however,
	  it should be closely monitored.
  	
*) Jobs for this week:

	- Continue cold vacuum tests and thermal tests 
	  for feedthrough -1.  A primary purpose of
	  these vacuum tests is to make sure that we
	  understand the characteristics of potential
	  leaks in either the feedthrough or the test
	  setup.

	- Organize the electrical test LabView VI's.

	- Write a LabView VI for the second fanout/scanner.

	- The `pigtail stretch' test remains to be done.

	- The temperature vs current test of a pincarrier
	  pin.

Agenda for next week: (MGF or RKK to chair)
^^^^^^^^^^^^^^^^^^^^^
- Milestones
- Report from PB on FT -1 progress and plans.  This report will
  include the results of the thermal tests, as well as the current
  understanding of leak check procedures.  PB will circulate a
  `list of procedures' document for the cold leak checks, along
  with a simple schematic diagram of the various volumes and
  joints being leak checked.
- Report from Mark on Ebco flange machining (?)
- AOB
