Present: CD, CR, MT, LB, DH, PM, DO, Stefan Sch., PW (TUDA)

- Minutes of the previous meeting, approved with no changes

- Hardware
   CCD camera knocked out of alignment.
   CR had problems setting up the DSSSD detector for calibration.
  Suggests that we clearly label connectors to make sure they are
  put in correctly.  Also, put polarized connectors on cables.
    Final slit box still coming down; exhibits ``anti-burps'' in
  vacuum.

- 22Na targets
   Moved Thursday morning.  DO & CR & Susy removed box and found
  different dimensions to previous different sets of dimensions;
  bigger, requiring modification of design.  Concerned that chamber
  had leaked up to air.  Activity was as expected.  Swipe tests were
  negative on box surfaces; 250 cts./min. on Faraday cup.  CR shows
  design from Cory.

-
   DH, inner & outer vessels are welded.  PW reports that inside
  surface of outside box -- surface as if for an O-ring is slanted
  (coupling that goes to TP's?).  DH says that this is just where
  two machined surfaces come together.  Machinist does not wish to
  correct; but wants to move on to keep the schedule.
  . . . other TUDA discussion, not recorded.

-
   CR: 2 PA's only mentioned on pro forma invoice of equipment
  shipment.  Otherwise list is complete.

-
   Vibrating wires; maybe before 23rd (PM).

-AOB
   CR: solar cells arrived today.  Brian Evans is away for ~2 weeks.
  Is there anybody who can do the soldering?  Revision of design
  to fill in the gaps.
