> The HAPPEx detectors have been installed.  Source work to minimise
> helicity correlated beam differences has been completed.  The Hall
> has completed the hot checkout and will lock up for first beam
> tonight.

> Currently, the major foci for work are on the HRS right dipole, the
> Compton in general and the in situ LED detector linearity
> measurement system.  There is also work being done on PREX detector
> tests.  We will lock up the hall for physics beam tomorrow (Friday)
> and run optics and pointing measurements over the weekend.
>
> There will be a general target training at 4 pm on Wednesday 26
> August.  Those target operators who have shifts before this date
> will be contacted separately to arrange prior training.
