Notes on Penn/NRAO-GB videocon

CDR
===

-Mark says the state at the end of April will be:

 *final optics design.
 *cryostat design workable but
    still with some uncertain 
    details.
 *detector design pretty final,
    but probably no devices. (so
    it may change).
 *list of electronics rack components
    but perhaps no real design for
    enclosure, modulo detailed GB 
    input.

-Basis materials for the CDR are
 *three documents
  +electronics interface document
  +software interface document
  +mechanical interface document
  +powerpoint presentations
	(we'll get these 1 week
	ahead of time)

-Some specific questions they have
 *RFI
  +can they simply turn off the
    MUX when Rx not in use, thereby
    presumably changing the spec?
  +has anybody ever *put* a computer
    in the receiver room before? If
    so perhaps that could be what
    they use.
  +Given a list of electronics components
    to what extent can GB actually
    specify an enclosure for them?
 *Money
  +they need money for Goddard
