Hi All,

The latest from the accelerator is that they think they will be able to 
deliver beam tonight.  So assume shifts are on.

They checked the cryo valves that closed last night and found no problems,
and moved some cooling power from one linac to the other to help stabilize.
So far they have been able to keep the valves open, and if that continues
will be able to deliver beam. It is of course not certain how well it will go.

Hello Everyone,

The North Linac had a "vacuum event" yesterday after gradual loss of vacuum
that resulted in no beam last night.  They are diagnosing today and will have news
this afternoon.  The solutions are not expected to be quick, so we may not be back
until after the planned downtime Friday-Saturday.  But MCC did suggest to still be
prepared for beam tonight.  Stay tuned.
