Minutes of the Jan 25 Tevatron Dept Meeting

* Weekly Operation Summary (Dean Still) - The Tevatron delivered 35.5 pb^-1
this week with initial luminosities between 105 and 270 ub^-1/s for the 7
stores.  The 4 stores with lower luminosity stores were hampered by the lack
of proper electron cooling in the Recycler.  All HEP stores were terminated
intentionally, but shot 5863 ended with a quench prior to declaring HEP - 
the HA24 dipole corrector tripped off, causing the beam to drift into a
collimator (investigation later found a failed butt-splice in the service
building).  Orbits have been smoothed, and losses through the squeeze are
acceptable.  During a 12-hr access for D0, the C17 separators were investigated
in the tunnel - no problems were found with any of the plate connections.
After that down period, multiple dipole corrector regulators required 
replacement.  The B48V separator polarity switch breaker tripped during a 
shot-setup and required a local reset.  The new studies request form (common
to all machines) is now active.

* Plan for Next Week

   - Deliver luminosity
   - E17 pinger timing (Dan & Bruce, 2 hr proton-only) (should be today)
   - Low-Beta Optics Measurements (Alex, 4 hr proton-only)
   - Make PBJ operational (Tan, Steimel, some no-beam time)
   - TEL-2 BBC (Seva, during HEP stores)
   - AC Dipole (Ryoichi/Andreas, proton-only)
