[BLAST_SHIFTS] run-plan weekend 11/15-11/17

From: Tancredi Botto (tancredi@mitlns.mit.edu)

The hall will be open all day saturday and sunday. The first priority
is to establish good beam thorugh the downstream spin flipper which offers
a somehwat reduced aperture.

* After CCR is done with optimization (I0, lifetime) tune the slits
  by looking at phys0 (elastic coincs), phys3 (front coincs), as well as
  phys1, phys2 (L and R singles) on the scaler screen.

* Measure the rate with all slits out. Optimize the slit position with
  empty target and with 0.2 SCCM H2. CCR controls the slit movements.

* After good beam or best-possible beam has been established we need to
  take 0.2 SCCM runs to study if backgrounds are considerably different

* At the same time - with a Wch person on shift - we can run the
  Wch, make sure the hall lights are off (I asked ccr, but check).

* We should finish the runplan of 11/14 as far as printng reference runs
  (see cb, mailing archive and/or NM)

* On sunday we should update the situation. We should consider taking data
and measuring rates for more "generic" triggers to study possibly multiple
events in a sector. (our triggers so far have always been 1 event/sector
only)
