<!-- Notes: -->
<pre>1) Take data with shot 
  a)Investigate peak of ~30ADC counts in data with delays 
    perform 0 delay run and 38ns delay run. 
  b) Take data scanning bandwidth at 38ns delay. 
     2,5 and 7 
 
2) Understand CLC data so that we can make offline cuts 
3) Incorporate trigger bits so that we can analyze data with 
   many triggers. 
4) CAENnet work.  Disable bad ladders 
5) Take pedestal run with optimal parameters</pre>

<pre>Matt sees very wide distribution of ADC counts with mean high  
ADC in all myron buckets. Tracked down problem to layer 1 on  
wedge 3 west. No bias current seen yesterday at all, HV logs 
from 10/6 and 10/5 indicate that bias current should occasionally 
produce a non zero value. Ran B4 in stand alone mode and looked 
at noise/dnoise. Large common mode noise seen on this ladder (but 
not on neighbouring ladders in the same wedge) both phi and z 
side. Conclude that ladder is not being biased properly. Will 
investigate bias connection/Power supply next access (Monday?). </pre>

See Matts plots in the following entries of ADC count 
distribution from the problem ladder.

Run 101426: BW 5 Delay 38ns 
has interesting COT events
<!-- Comment: Mon Oct 16 07;43;33 comment by...SCN -->
Run 101405 should have been 38 ns Delay (2) bw 2...I think

<pre>Problem with west wedge 3 layer 1(offline 2)(power supply 27) 
 
Bias current history showed no current draw for a few days. 
Channel had previously drawn 1-2uA 
 
Test stand runs showed unbiased behavior. 
 
Setting bias voltage to 0 and back to depleted value fixed the 
problem.   
 
However, channel reads a minimum of 18V.  This problem 
has been observed at SiDet.  Bias channels with this problem 
do maintain the correct voltage if above the minimum value.  The 
above problem of the sensor not being depleted has not been 
seen before.  
 
Recommend looking at the power supply on an access.</pre>

<pre>Beam in machine, but they will be doing beam tuning studies 
all night.  So beware, the ped runs (and everything else  
tonight) will be taken under these strange beam conditions.

<pre>Re-running PED run to make 101260 the default ped run. 
It has DPS *on*; we had 101264 in before, which was DPS off.

<pre>Took ped run 101458 with magnet on, DPS=on, thresh=5, BW=5 
Changed the HWDB to NN.   
 
Transferred SVX power supply GUI to ACE, and snuck out a  
little early. 
 
SVXPED run is still running, will finish around 1am.</pre>

ped run in integration mode


<!-- Comment: Sun Oct 15 10;41;45 comment by...AFS -->
The above means that this particular run (only) was a magnet-on, dps-on, readall mode run to use as the new default pedestal and dead/hot/noisy reference, if it checks out OK in offline analysis.

<pre>Calib consumer program offline apparently worked last night. 
No date or time was on the screen, but the program ended normally 
with the message: 
Wrote Download pedestal/threshold data for run 101260, version number -3
