Dear all,
  I must specify the number of backframes in a request for
bids from vendors.  There are many sizes, and I need a
quantity for each.

1) 3GEM+Gate       27.0 mm
2) Micromegas        41.8 mm
3) Pixel GEM          40.5 mm
4) 3GEM, no Gate  37.0 mm
5) Simple Bias Board   (41.8 mm ??)

There may be other requests. Now is the time to make this
known.

I am assuming we can make simple bias  modules using
3.2 mm PCB, the same as the Micromegas. Is this true?
(Who will be responsible?)

There will be 2 each of items 1,2,3. The holes in these
have been moved on Friday, January 25, and I expect to
be able to send them soon.

Please think about the required quantities so we can finalize
this on Jan 30.

Regards,
Dan
