E811 Run plan

At this morning's 9 O'Clock, Win Baker indicated that he knows of
no reason they will not be ready to begin their running period at
8AM on Thursday 18 January 1996. They are suffering noticeable
degradation to some of the electronics they installed last week
(from Main Ring losses), but this is not expected to compromise their
readiness if the run takes place as scheduled. {It does provide
additional motivation for them not to delay running}. They
were comfortable with Alan Hahn's request for a 6 hour window
(8AM-2PM) on Thursday for ending the last store before their running
period begins.

Win gave me a copy of their "idealized" run plan, which I reproduce
below. It is subject to many many caveats, but indicates how they
would like things to go. Note that they are thinking about a 24
hour cycle, with stores lasting for ~20 hours. Also note that Day
1 may have the luminosity pattern of store 2, rather than starting
at low luminosity.

One thing that is clear is that we will have many long hours in the
Portakamp during this period. Please let me know your availability
during this time, so that I can try to arrange things so that we
don't have people taking 120 hour shifts. [I have not pressed hard
on this before because of the uncertainty in the E811 schedule].

--------------------Start of E811 Schedule---------------------------

E811 Run Plan (1/5/96)
W. Baker

Day 1 10:00 Start shot setup for low t run: 6 on 6 bunches,
Store 1 6E26 luminosity at E0, 1500 hz maximum singles rate
(1/18/96) at 2.8 mm detector positions
14:00 Start low t data taking

Day 2 10:00 Start shot setup for efficiency calibration run:
Store 2 6 on 6 bunches, 1.5E28 luminosity at E0
14:00 Start calibration run for cluster efficiency
23:00 Scrape to 6E26 (store 1 conditions); take low t data

Day 3 10:00 Start shot setup for inelastic calibration run:
5 on 5 bunches, store 1 conditions
14:00 Start inelastic calibration run

Day 4 10:00 Start shot setup for low t run
store 1 conditions
14:00 start low t data taking

Day 5 10:00 Start shot setup for low t run
store 1 conditions
14:00 start low t data taking
until 10:00 of day 6

NOTES: It is estimated that main ring can restore stack running
approximately 50% of the time, depending on conditions of
each store. E811 will determine when to shut off main ring
ramp during each store consistent with restoring stack.

This schedule allows for 70 hours of low t data taking,
approximately 25% of which will be lost to main ring
operation, yielding 50 hours of low t data
