Start of Shift Notes:  

Inherit Store 3252 with lum 13E30 and a cosmic ray trigger  
test run in progress.  Plan was to drop the store at 4 p.m. 
and go into shot setup, but this still hasn't happened yet. 

• I terminated the same run twice! Pretty cool, huh. actually, this is what happens when you don't select either "Potentially Useful" or "Definitely Garbage" boxes when ending the run
• We tested the table PHYSICS_TEST_2_02 [9,428,432] which has UDPS in it. We had hoped to test it with some beam in the machine, using the Calorimeter triggers to get the high rate, but due to several delays beyond our control, they ended the beam before we could get the test going. It did run, at a whopping 9 Hz.

Looking at the low-level bc mismatch errors that  
occur when reading out the TDCs in "dual-fifo" mode.  IMU 
crates 00 and 01 have been programmed in DSP V45 (which  
uses dual-fifo-accecss mode) 

Can reproduce the errors at a low rate (once per 15 minutes  
or so).   Will try to include crates in the main partition, too. 

BC errors in IMU crates are happening at a higher  
rate than when I was using the SEVB, presumably due to  
the higher possible L2Accept rate (measured in clock time) 
Perhaps once every minute or two. 

A very strange clue is that BC errors come in 
bursts during this run -- IMU BC mismatches 
correlate in time with XFT bc mismatches.   The correlation 
is not exact, as the event numbers disagree.

Have put both IMU crates into "spy-mode" readout,  
with dmaChain=true. 

This run was a disaster, with every 
event in the short run with errors.

IMU crates have been deprogrammed back to their  
original configuration, including TDC DSP=37, dmaChain=false,  
and spyMode=false.   Must scrutinize the error logs in  
detail to extract some conclusion. 

Shot-setup-run starting with IMU crates back to normal. 

Two things of note from MCR elog.... 

1)  Mon Feb 23 19:06:39 comment by...BME --  It looks like 
the F49H collimator did not move all the way in. The plot  
on the left shows the final position during the last number 
of stores (~+400 mils). Currently the collimator sits at 
~+76mils. We are attempting to contact Dean Still.  

2) Remaining pbar stack (28 mA) was lost due to problems with 
A:IB. (Note sure what that is but problem is with transformer 
that regulates this device.) Stack was lost at 1943 and has 
still not returned.

...also FRED unprescaled trigger bits 35 and 43 differ substantially from TFRD

* 16:10 Store 3252 is dropped and the Tevatron goes into
shot setup with a stack of around 200 mA. We have *no* quiet time, so we don't take calibration
runs. 


* 17:00 Bill Badgett works on TDC DSP microcode for about an hour using two crates during a cosmic
ray run while Tevatron in shot setup. 


* 19:00 Store 3254 from a pbar stack of 180 mA.has intial luminosity of 53E30. We take ~500 nb^-1 of
good data at an efficiency of around 93%. 


* 22:00 Luminosity drops below 40E30 and we begin an hour-long UDPS test run. Jonathan Lewis happy
with it: "this run is a beautiful thing!"  


* 23:20 Resume taking physics data with low luminosity table at 35E30. 

During the shift there are two instructions from JJ: 
  1) Watch for and log problems with the Voice Scheduler (see e-log). 
  2) Restart Stage 0 once per shift to avoid memory leak problem.
