Dear All,
	Yesterday it was found that the AP30 heat exchanger for the cryo
helium was contaminated. The initial guess (which was reported at last night's
weekly meeting) was that stacking would not commence until late in the
weekend while the cryo system recovered. However, the cryo people were able
to isolate and decontaminate late last night and now the system will be ready
for stacking this evening.
	The other accelerator work is nearly on schedule. It is expected that
first beam will begin soon after 18:00. With the preliminary check-outs
and such, stacking probably will not begin close to midnight. With all of the
usual caveats about startups, the earliest deceleration could be expected 
on Saturday's evening shift (day shift should check early in the day to
see if they will be needed near the end of their shift).
	Now all we need is a stack size and deceleration energy!!!!
