[BNC-all] Evaporators

[Dave Lubelski]

The three metal evaporators will be down through the weekend.  The Airco
has a mechanical problem and a part is on order.  The Varian is down due
to a student venting the cryopump to atmosphere.  This fix may include a
new cryopump.  The CHA has a blown high voltage power supply which is
being worked on currently.  If any change in status occurs before Monday
and email will be sent to all cleanroom users.
