<pre>North-East and South-West CCUs were rebooted during this 
morning Controlled Access. 
Voltages were updated</pre>

This is only a test.

<pre>May 16 16:15 pm. We checked ONCE MORE again the correspondance of CSX counters 
signal channels to their HV channels. Especially we checked all 
counters with low efficiency and other ones (every 8-th counters). No counters with wrong correspondance were found on 
level 1 (Counting room). 
We are going to check AGAIN the correspondance of HV (or signal) 
channel to CSX counter ID in collision hall during June access.

<pre>About false alarm for CCU15. The order of CCUs in port 4 - 
17, 05, 15, 12. When I changed configuration file (the order -  
17, 15, 05, 12) false alarm for unreadable CCU12 was appeared! 
All alarms were disappeared, when I defined the order as: 
17, 15, 12, 05.  
CCU05 somehow influence the next CCU in port 4! But it doesn't 
influence the next CCU in the next port 5  
(I mean CCU20 is the next)...  
Thanks to Fiodar, we thought together about this problem.</pre>

<pre>We have some CSP counters with very low efficiency. We inceased  
voltages to check efficienies after this: 
 
CSW NW, Pb8:   chan. 4:  1943 --&gt; 1963; 
               chan. 15: 1837 --&gt; 1900; 
------------------------------------- 
CSW NE, Pb9:   chan. 0:  1934 --&gt; 1957; 
               chan. 6:  1877 --&gt; 1910; 
               chan. 24: 1946 --&gt; 1980; 
               chan. 25: 2017 --&gt; 2050; 
               chan. 27: 1958 --&gt; 1980; 
-------------------------------------- 
CSW SW, Pb11:  chan. 0:  2060 --&gt; 2080; 
               chan. 33: 1806 --&gt; 1840;

               chan. 38: 895 --&gt; 920;

CSP TE, CCU19: chan. 29: 845 --&gt; 870; 
               chan. 38: 825 --&gt; 850.

<pre>There was power outage this morning. 
PC was rebooted, voltages on CCUs were updated (we did it 
together with Gervasio). 
System was checked, system is OK!</pre>

CCUs are set to 0.<br> 
Gammmma boxes are switched off <b>except one for MSK</b> - maybe switch is broken. HV on it set to 0<br> 
Camac crate is off<br> 
PC ShutDown<br>

Happy power off!<br>

<pre>Changed dead pads on bottom CSP 22E (CCU ch 22) and 28E (CCU ch 28). Tried to change pad on Bottom CSP 1E but found it to be inaccessible. 
 
Found that signal cables at the patch panel for CSP 15 NE and 12 NE wer interchnaged. Fixed, 
This should explain low efficiency previously observed for these 
counters. 
 
Checked CSX pulse widths for all CSX arch channels. Found widths 
to differ by as much as 15 ns around a 50 ns average width. </pre>

<pre> Yesterday evening, The ace took a "physics" run  which is actually a CSX "discriminator calibration run".The following is an extract of the shift log. 
**************************************************************** 
   Tue Jun 11 17:38:51 Run 146248 Terminated at 2002.06.11 17:36:39 - RunControl

  L1 calib continuous  
  L2 auto accep  
  L3 Software Evb  
  Run type: Physics  
  no trigger table used  
  crates: CMX00, MUON_SCINT_00  
************************************************************* 
 
For this run, the CSX discriminators were being pulsed with 
a clock - synchronized pulse evey 396 ns. 
HVs were 1000V below normal voltages.</pre>

<pre>We were paged by SciCo because of alarm in Control Room. 
We found that There were no power on CCUs on the West Side of IMU. Rob told that this due to power brakers were installed, but control for them is not yet implemented. He said that this maybe will be done tomorrow.</pre>
