<br><b>b0ccal06, wedge 20 wide pedestal:</b> 
<br>Problem with wide pedestal tracked down to inappropriate 
grounding in swapped cables.  While removing the cable swap 
earlier, 2 8ns cables were installed to swap wedge 20, PMTs 
5L with 6R.  One of the LEMO barrels was connected to the kick 
plate (dressed there).  Corrected this problem and the PEDRMS 
went  to around 2 cnts.  The problem needs to be corrected at  
the transition board and the 8ns cables removed.  Will wait 
on this until tomorrow or the next access.

<pre>Today, I circumcised the following CEM phototubes: 
 
	4L8E, 6L8E, 9L8E, 0R13E, 0L13E, 3R13E, 4L13E, 
	5R13E, 6R13E, 7L11W 
 
5R13E was only a partial circumcisium as it appeared that some 
of the vellum paper had already been removed from around the 
transition piece.  In addition, I cleaned 3L13E.

<pre>Based on Rick Tesarek's data taken last night for the CEM, I redid 6L8E phototube's vellum paper wrapping.  Managed to get off some more paper near where the photocathode would abut.  After bringing the HV back on, I find the tube looks quiet now. 
Rick Tesarek worked on a tube in 21E,  I believe it was in tower 2.</pre>

<h3> Wall source calibration: 
<h4> 
 We want to recalibrate some of the PMTs which have LERs "out  
 of range" (LER>2.5 or LER<0.6). Magnetic field is on. 
<br> 
 We need first to download unit LERs on the ADMEMs before the  
 source calibration. We follow Rick's procedure: 
<br> 
 allocate the wcal crates <br> 
 run reboot_wall script <br> 
 run calib_wall script 
<br> 
 The last step was done twice because the first time we got busy  
 messages from some crates. The second time everything was ok.  
 <br> LERs should now be 1. <br>  
 <h3> Proceed with source calibration. <h4> 
 <br> 
1) Take a laser run with default HV settings (run 122292) . 
<br> 
2) Take a source run with default HV settings (run 122288) 
<br> 
3) Adjust the HV for the PMTs in calibration and take a new  <br>   source run (run 122294) 
4) Take another laser run with the new HV settings (run 122295) 
<br> 
5) Reset the HV to original values and take a QIE calibration <br> to restore the default LERs<br> 
6) Take an extra laser run after QIECalibration (run 122302) 
<br> 
In the process of restoring the HV we found that one channel  
<br> (19-W 8L) got stuck (reached higher limit) and doesn't  
<br> restore to original value. It is off by 53 Volts. There 
<br> is a controlled access and we are going to restore the channel manually.

Found readout problem. At first I've had an impression that this 
pisabox was out of power. But after restarting program everything 
seems OK.
