<pre>COT Validation starting on Monday Feb.18</pre>


<!-- Date: Mon Feb 18 19:25:51 2002 -->
This file starts from were Eiko left (i.e. run 139339 taken at 8:43 am on Feb.18). No good runs are available so far after that. 
 
I will also include some emails that have information about the problems seen in the previous runs.

<pre>FROM KEVIN at 9:20 am 
 
Regarding the appearance of a dip of ~200 um near 0 drift 
distance: 
 
A few months ago we changed some of the drift model parameters 
that are NOT fit every run, in order to improve the shape of 
the residual vs. drift distance plot near zero.  When the big 
dip returns, as it did last week, this means that we have 
somehow picked up an old calibration. 
 
Looking at the COTStage0 entries in the database last week, 
it looks like after run 138865, two entries were made for 
run 128066.  This is the run that is kept on partition 14, 
which the consumers use when we are not running.  Running on 
partition 14 does not normally make a database entry, but 
this time it did.  The result was that the change to the 
constants to get rid of the dip near 0 was undone. 
 
I will load a more correct set of constants by hand between 
stores today.  Whoever is doing validation this week (Joao?) 
should check the data we take tonight to see if the dip is 
gone.

  Status of TDC failure studies and possible things we can do. 
  
STATUS: 
-------------------- 
- There are no TDCs presently in the system that are in a bad  
state all or most of the time.   The ones that fail (6 known to  
be in the system at the moment), always do so at the beginning of 
 a new run.  In January, TDCs were removed that were bad in every 
 run or a large fraction of the runs. 
  
-  I have never seen a case where a TDC failed in the middle of a run. 
  
-  Explicitly examined state of all TDCs after 10 to 15 HRR's in  
mid-run: HRR never caused a problem. 
  
- In 3 of 4 cases where a TDC failed at the beginning of a run 
 and there was at least one HRR during the run, the TDC recovered 
 after the first HRR.  Furthermore, it was determined that the  
HRR caused the recovery.  The TDC was bad within 10 seconds  
before the run stopped for the HRR and was good within the first  
10 seconds after the HRR. 
  
- In 1 case the TDC did not recover after ~10 HRRs during the  
run.  This TDC was replaced in January. 
  
- In 4 cases in which a TDC failed at the beginning of a run and  
there were no HRRs during the run, the TDC did not recover during  
the run.  It was ok when the next run started. 
  
 
THINGS WE CAN DO? 
------------------------------------------- 
- For the TDCs, it would be advantageous to issue an addtional  
HRR either at the beginning of the run or very shortly into the  
run.  However, Arnd implied that this may cause problems with  
other detectors. 
  
- Arnd said that we could try modifying the command sequence  
during the "Cold Start" at the beginning of a new run.   
Essentially, it sounded like increasing the delays between  
commands, which he said were already quite large.  This certainly  
seems worth a try. 
  
- Modify YMon to calculate specific "TDC average" quantities and  
issue an error message upon failure.  The shift crew would then  
likely try an HRR or if need be, start a new run.  This would  
take much of the guess work out of looking at YMon plots. 
  
- Continue trying to use the TDC test and calibration programs to  
determine what in the Cold Start is causing the TDC to go into a  
bad state.  Kirby started looking at this during the last down  
time. 
  
 
DETAILS OF THE NEW "YMON TDC ERROR MESSAGES" 
--------------------------------------------- 
 
  Whether the TDC fails due to occupancy or average time shift  
problems, the values can vary greatly from channel to channel.   
Given the present known failures, the most sensitive indicator  
would be to sum the absolute values of the difference between a  
channel's present value and that from a known good run.   One  
should exclude known bad channels from the TDC averages, which  
means someone has to prepare and maintain such a database.  We  
can use known TDC failures to determine where cuts should be  
made.

We have started taking data from store 1002. The first runs (139367 and 139368) are using the correct Stage0 constants. The dip in the 
residual plot is gone. 
 
Run 139368 has 5 cold cells in SL7 (#320 - #324) which were fine 
in run 139368. Will look into this further tomorrow with more data.

  I have compared this runs with run 139338 which was a recent run with 61

so,  unfortunately there is not much data for that run. <font color="#ff0000">

    <li>There is a RMS residual improvement relative to previous runs of 
about  4-9 microns due to the use of new Stage0 constants. These new constants 
eliminated  the dip close to the wire seen in the residual vs. distance plots. 
The residual  mean shift was in the range of 1-11 microns.</li>

  The table shows the data in a "pseudo"-histogram form. The hot and cold  
cells columns show all the cells that<br> 
  were hot (or cold) in at least one of the runs. The columns label "runs" 
 show which runs had the respective cell<br> 
  in error. &nbsp;The runs are labelled from 1 to 5 according to the key 
in  the table above. Real hot cells will be present in multiple runs. (For 
instance,  SL2, cell 159 is cold in four runs (1, 2, 3 and 4). So, it is 
a real cold  cell. SL2, cell 31 is cold only on run 2. It might be a statistical 
fluctuation  or it might be real - since it has showed up before it is probably 
real).  <br>

<pre>Preliminary checks of COT after SL4-227 HV disable and FADC 
installation look good.  Bill, Ayana, and Melissa put new 
FADC's in crates 8 (slot 20) and 16 (slot 21). 
 
I did get a timing glitch on my first run, crate 7, slot 19: 
 
   SL7-296 (C,492,07-19-0): OKAY  
   SL7-297 (C,492,07-19-0): T = 307.4 (437.0+/-4.5) -129.7  
   SL7-298 (C,493,07-19-1): T = 307.9 (437.0+/-4.5) -129.1  
   SL7-299 (C,493,07-19-1): T = 309.1 (437.0+/-4.5) -127.9  
   SL7-300 (C,494,07-19-2): T = 309.5 (437.0+/-4.5) -127.5  
   SL7-301 (C,494,07-19-2): T = 310.5 (437.0+/-4.5) -126.5  
   SL7-302 (C,495,07-19-3): T = 307.6 (437.0+/-4.5) -129.4  
   SL7-303 (C,495,07-19-3): OKAY  
 
On my next run, I closed and reopened my partition.  The problem 
did not reappear.</pre>

<pre>Summary of report on access to WEST plug from Bob Wagner on Feb.22 
 
Report on access to WEST plug (HV: SL4-227-01, HV: SL5-165-all, SL8 noise) 
  
I. Summary 
II. Background 
III. Report 
  
 
============================= 
I. Summary: 
============================= 
  
--&gt; SL4 cell 227 S1 was disabled.  We will start running S1 in 
the rest of quadrant D at full voltage (it was 80v low).   
XFT has been notified to unmask. 
  
--&gt; SL5 cell 165: HV daughterboard was found shifted by 1 pin.  
 This was corrected.  Dave said readout is now ok and the hole  
in STAGE0 should disappear. 
  
--&gt; Faraday cage connections improved over some noisy SL8 cells  
(33, 41, 153, 205, 262/3, and 275).  Since the power was off, 
 we could not use SPY to check if the noise was actually reduced. 
  
 
============================= 
II. Background: 
============================= 
  
 The COT group requests an access to address two problems on  
the WEST endplate (requires WEST plug pull): 
  
1.Breakdown of SL4-S1 in cell 227. 
 We are now running SL4-S1 at a reduced voltage (80v below  
nominal) for the entire quadrant D.  We would like to disable  
this channel in cell 227 by removing the 300 ohm resistor on the  
HV daughterboard and tieing it to a neighboring potential wire. 
 
  
2.Bad connection of the HV daughterboard for SL5 cell 165. 
 All channels in this cell are essentially unused in STAGE0,  
have average times shifted by 40ns in YMon, and have a  
persistent reflected pulse using  the calibration.  This HV  
daughterboard was unplugged during the wire pull in November.  
 It must not have been reconnected properly (possibly in more than one respect).  
  
The work on both problems can be completed in 2 hours after the 
 WEST Plug is out and the platforms installed.  The estimate  
for the entire process is about 12 hours.  A JHA already  
exists for the Plug pull and work with argon/ethane in the COT. 
  The following people will likely participate in the access:  
Wojciech Blaszynski, Wanda Newby, Ines Ramos, Kourosh Taherie, 
 Bob Wagner, Aseet Mukherjee, Ting Miao, Morris Binkley and  
Dave Ambrose. 
  
ps.  After making the above access request, we thought it would  
be worth checking and making general improvements to the  
Faraday cage over HVDBs for some noisier than normal SL8 cells.  See item 3 in the Procedure section below.

<h2> From Store 1018: </h2> 
           
<h4> </h4> 
    
<h4> Run 139783:</h4> 
Run 139783 is so far the run with the highest luminosity from the new Store 
(1018). <br> 
I have compared this run with run 139371 from store 1002 which was 24 nb-1. 
Overall, the access improved things substancially.<br> 
       
<ul> 
     <li>New hot cells: SL1 - cell 1; &nbsp;(SL6 cell 45 is much hotter than  
 before.)</li> 
     <li>SL4 - cell 227 is colder than before (sense wire 1 was disabled 
during access)</li> 
  <li>SL5 - cell 165 is now fine (daughterboard was shifted into place).</li> 
  <li>SL8: Many previous hot cell are good now. These are 33, 41, 153, 155, 
205, 259, 262, 263, 275, 279.</li>

   I will use run <font color="#ff0000"><b>139378 as a the reference run</b></font>

<h4> Residuals: </h4> 
The RMS residuals from  run 139783 are consistent with the previous store. 
There is a improvement of 1-4 micron for every SL.<br>
