<pre>Shot setup in progress.  13 proton bunches.</pre>


<!-- Date: Sun Apr 28 16:14:44 2002 -->
<pre>We inherited a cosmics run (number 143979). 
Final protons injection almost completed. 
I'm going to start a run on partition 0 with no silicon and 
physics table PHYSICS_1_01[7,43,289]. 
Later we'll switch to partition 1 when/if silicon will be on.

I noticed when tried start the open a ObjectMon from socket, there were two ObjectMon: from b0dap30 and b0dap56. 
from the b0dap56 have still empty HADTDC Timing plots, 
from the b0dap30 have no empty HADTDC Timing plots,  
but like a wrong MET distributions.

<pre>
As can been seen from the above plot, around 1703 the TEL was
turned on, which resluted in the first spike. 
Around 1730, the separator HV turned on. What is expected is 
that no collision b/w protons and anti-protons at B0 and both
abort gap beams would decrease, but they look flattened out. 
</pre>

<!-- Comment: Sun Apr 28 20;08;27 comment by...R. Vidal -->
these abort gap halo rates are still slightly contaminated by collisions from the last of the 12 bunches, thus they follow the change in B0 luminosity; from the timing on the scope, it looks like the abort gap gate needs to be shorten another 20-30 nsec to eliminate this residual rate from collisions (<b>Rick please note</b>)...

-A49 Hor. Separator Voltage output is just 25KV (out of 90KV). 
As a compensation, the +A49 Hor. Separator Voltage was knobbed to 110KV from 90KV. This resulted in the Lum. Increase at B0.

<!-- Comment: Sun Apr 28 20;29;00 comment by...R. Vidal -->
these are the losses from the top proton Halo counter for the abort gap between
proton Bunch #12 (on the right) and #13 (on the left); the residual peak is from the collision of Bunch #12 with pbar Bunch #36; the abort gap gate needs to be
shortened by about 20-30 nsec (see right histogram) to eliminate any remaining contribution...

<font color=red>Shift Summary: </font><pre> 
      Evening Shift Summary Sunday  April 28, 2002  Debbie Errede 
      ------------------------------------------------------------ 
 
1607  Shot setup in progress.  24 proton bunches in the Tevatron.   
 
1619  4 antiproton bunches in.  Average about <16> in pbar units. 
 
1639  Tevatron at flattop.  All pbars in. 
 
1643  Scraping has started.   
 
1658  Scraping is completed.  SVX guys have been paged. 
      Turning on high voltages...including CLC.  B0lum = 8.77 10**30. 
 
1702  Starting run # 143980, store 1258.   
 
1729  Alarms:   COT, CMP, CPR.  See losses in lostp and b0rat2. 
 
1736  we called MCR: just ratcheted up Separator A49 voltage... 
      horizontal plane.  We believe this caused the spray into 
      our detector.   
 
1744  Rick Vidal:  notices that the effect of this notching up 
      of hv on the separator is to fill both the antiproton and 
      proton abort gap.  monitors: b0pbsm, b0absm. 
 
1750  We also note that the inst luminosity jumped to 12 10**30.. 
      ...initially the b0LUM was 8.7 10**30!!!   
      MCR says that one of the power supplies for this separator 
      had failed and wasn't on when the beam started colliding 
      which was the cause of the low luminosity given 
      such high proton and antiproton numbers in bunches.  They then 
      attempted to notch up the voltage on this separator...causing 
      the spike which tripped our chambers.   
 
1839  MCR: the device on acnet is C:A4SHM which shows a lower voltage 
      (25kV instead of ~110kV).  To compensate, they increased C:A4SHP.   
      (the positive plate on the separator).   
 
1900  Rick Vidal noticed that this separator had low volts since 
      the last good store Friday night (April 26).   
 
1920  Rick has figured out that this is the cause for the loss 
      of 10% of our inst luminosity yesterday at 9:10am (Sat).. 
      the power supply failure on separator A49.   
 
1942  Because we are running in non-standard conditions 
      (vertical and horizontal separators at non-standard 
      voltages) the silicon probably won't be tested today. 
 
2050  D0 is putting in their roman pots.  
 
2203  Ten O'Clock and all is well. 
 
2358  Running calmly.
