Comments:

 1 DAQ hangs cured with resetting
 1 Nozzle unclog

1. SNAFU

08:00 FCAL was missing TDC hits since the beginning of the stack.  Called
experts MG & SS to fix.  ECL cable attached and TDC hits reappeared.


2. TARFU

11:15 Jet communication was in error.  Used procedure twice to fix the
problem.  Then rebooted the Jet Mac w/permission from GG.

11:42 Straws tripped.  Reset sucessful

3. FUBAR

11:50 MCR called that the stack is gone.  Beam valve between AP-40 and
AP-50 closed due to bad vacuum.  Jet target experts are investigating the
cause as I write.


SNAFU->Situation Normal All Fouled Up

TARFU->Things Are Really Fouled Up

FUBAR->Fouled Up Beyond All Repair



Have a nice day

13:30 After an access.
                         
   A 24 power supply of the jet target tripped off and shut all the
   pumps down. 
   Cary, Sally and Gabriele went donwstair and resetted the power supply. 
   After that they could turn everything on again.
   A fuse blew on one of the GOULD modules in the counting room, this may
   have caused the tripping. They are waiting for Dave Miller to replace
   the fuse, since we can run without that module.
   

 Dear Nadia,

 thankyou very much for your addendum - a comment.

 We don't know why the 24 volt died..it's not clear that it is not connected
 to the fuse blowing...so I don't think we should replace the fuse before
 we check things out rather carefully ..and/or at least only do the 
 replacement when there would be time to recover from another 24 volt failure. 

 The reason I am pointing this out of course is that it would not be a good 
 thing if we spoil the vacuum in the pbar source.
