<pre>work done on the East Plug: 
1)widened the holes on the cowboxes to insert insulating washers. 
2)swapped two defective cowtails. 
The HV may be raised now on the East Plug. 
The West Plug laser waned off, so I swapped it with the  
new one and re-adjusted the optics. A RC run was taken.</pre>

Willis and Howard are still working somewhere on the plug, so we'd better not turn on any plug HV until we hear from them.

<pre>An afternoon of fun with L2:   
 
1) upon arriving alpha in top crate was dead,  would not respond to minicom.  
2) swapped with bottom alpha which responded in minicom but 
wouldn't boot over network due to network changes this 
morning.  This was finally fixed.   
3) Original alpha was confirmed dead by plugging in bottom crate. 
 
1-3  took about 3 hours. 
 
Then took runs with various L2 interface boards.   
 
1) Found examples where Isolist was holding up the bus,  some 
of which were due to not receiving Ddone from the alpha and 
others which were not. 
2) L1 interface board only sends data for first L1A in  
myron mode. 
3) Clist stops sending data when Reces is plugged in,  but 
L1 interface continues fine.   
 
Greg and Carla are now checking L1 with the partition we 
were using...</pre>

<pre>I have finished using b0puls01 and b0wcal02.  They had new 
FER code loaded for TOF calibrations but I remembered to 
reboot them.</pre>

<pre>West PHA wedge 11 "plug tower 7" readout problem tests done in 
todays access 
 
  1) This is PCAL03/ADMEM 15  
  2) Readout problem traced to ADMEM transition card cable  
     swap: channels 1 and 7 are swapped</pre>

<pre>I changed the matching between PD outputs and cows on the West 
Plug.</pre>

<pre>CMP Access Report: 
 
We noticed a loose screw on the faceplate of CMP Top Stack 25  
(one of the smaller screws which screw into the pillar which 
holds the preamp board onto the HV board).  After tightening 
this screw all of the 12 MHz oscillations seemed to disappear. 
We're still not sure what the source of the oscillation was,  
but tightening the contact to ground on this particular stack 
seemed to elliminate the pickup.  So, the NOISE in the CMP Top 
chambers is no longer there. 
 
We spent the remainder of the day today trying to solve HV and 
signal problems in the Bottom chambers of CMP.  We swapped out a 
bad preamp from Stack 62 on the Bottom and revived one channel. 
The HV problem in Stack 53 on the Bottom has been pinned down to 
an internal problem with Layer 2, and a special HV connector will  
need to be made to jumper that problematic channel out. 
 
The CMP Bottom HV has been brought back up and is once again under 
the control of the shift crew.

<pre>The laser run taken with the west plug this early afternoon 
is propably not good since the new laser that substituted the old 
one was not timed in again. The calibration interval has to be 
determined for new laser and used in the configuratio files. 
We could see no events in the event display (except from the 
first one). Diego will do this calibration interval study 
later this evening and we should take another tun with west plug, 
about 10,000 events.</pre>

<pre>-had some problems trying to start a cosmic run after getting L1 
and L2 back.  cleaned up EVB, had to restart run control... 
experts still have some of the detector, but run seems to have 
started okay finally.  plan is to continue cosmic run until plug 
laser (new one) has been tweaked up, and then take the run for 
Vaia if possible.

<pre>ended run after ~1.2M events to give up pcal crates to expert for
work on laser.

<pre>started another cosmic run, sans plug crates.

<pre>-boxes on L3 display for processor nodes 85, 98, 99, 115 are 
gray and show zero event count.  unresponsive to resetting the
display window.
