ADDENDUM: HALL B HAS DEFERRED TAKING BEAM UNTIL WEDNESDAY.  We have 
another three shifts to utilize for beam studies as this is productive. 
  But remember, you'll have to provide a summary for the Wednesday 
meeting Beam Studies report.

Kent Paschke and Mark Dalton have submitted a test for studying
"Helicity Correlated Asymmetries" and its required half-wave plate has
been repaired so the measurements are possible.  I have provisionally
re-scheduled this for 20:00-24:00 today, 12 July, displacing the following.

I believe that the NL recovered cavities have been placed back into
service.  This may happen for the SL during "slow times," and so may not
require much dedicated time.

The 08:00 slot is to be used for the displacement measurement, rather
than continuing the series of autoquad measurements.

I have been told that Grames cannot support this time, but I do not now
know about Ken Law.  I may divert some of this time to injector
transmission vs. laser pulse length investigations.
