<pre>b0cot05 power supply failed at 7:52am this morning.  See lots 
of errors from run 125518 on due to this.</pre>
<!-- Author: Evelyn Thomson -->


<!-- Date: Mon Sep 10 10:18:04 2001 -->
<pre>b0cot13 power supply failed during Sunday day shift.  This crate 
sets the thresholds for crates 13,14,15 and 2 TDCs in crate 12. 
No power means no thresholds means 1.7MHz xft track trigger rate! 
Paged at 19:13 for advice on how to mask off these triggers. 
Advised paging XTRP as XTRP boards have capability to mask  
segments (in this case wedges 9 and 10).  
 
Owl shift runs were for beam angle studies, 3 day access in 
progress now.

 TRGSim SUMMARY AFTER 35226 EVENTS  
 **********************************  
First event's errors are all tied to b0cot06 7B and 6A - 
problem with data sent up from XTC? boxft04 slot 9 1a would be 
plus neighbour on b0xft04 slot 8 and vice versa for b0xft04 slot 
8 1b, with data shared on finder backplane.  Linker errors appear 
on a board that receives data from b0xft04 slot 8 also. 
 
Linker hot spot in board 14 chip 10 - b0xft03 slot 16 - wedge 8 
on xtrp.  No linker or finder errors nearby. Don't see spike in 
finder pixels.  Could this be an xtrp problem?

<pre>        In the hardware database, I've set the dead wire bits ON for COT 
sl 4 (second axial layer) cell 227 wires 0,2,3,4,5.  I did this at 16:35 
today, so the change should be downloaded at coldstart from the 
hardware database for runs 128023 on. 
 
        Previously, there was a 30% drop in track occupancy at 4.9-5 
radians.  The COT group have disabled the high voltage for these wires. 
Setting these bits on may cause a small over-efficiency, we'll see how 
much. 
 
For reference: 
-------------- 
These wires are used by the SL24 finder in b0xft00 slot 14 chip 2A. 
 
This is board 01 cell 47 in the trigmon finder occupancy plots. 
 
In hdwusr.CardEditor speak, this is XFT_FINDER09, DEADWIRE20 
 
DEADWIRE[9][20]= 0x f40000 (15990784 in decimal)

<pre>Occupancy for chip 2a on b0xft00 slot 14 increases to 11,000 over
an average  of 9,000 (left: 2nd histogram from top).  22%
increase in occupancy for this chip.  

No sign of a dip or spike in track occupancy (left: lowest
histogram)- good!  Look at fake rate too.

Occupancy for cell 2 is 4,000 (+60%) and for cell 3 is 3,400 (+40%) over an average of 2500 (right: hot spots).</pre>

<pre>What the occupancies looked like before the dead wires in cell
227 sl 2 were masked.  (Run 127413)</pre>

<!-- Comment: Tue Oct  2 10;36;32 comment by...Evelyn Thomson -->
<pre>Before masking, b0xft00 slot 14 chip 2a's occupancy was 25,000 (-40%) below an average of 40,000.

The track occupancy was low at 250 instead of 350 (-30%) for 3 linker chips or 3.75 degrees.

Occupancy for cell 1 was 8,000 (-20%), cell 2 was 1,000 (-90%), cell 3 was 3,000 (-70%) below an average of 10,000.

<pre>Today I performed XFT T0 timing scans.  In this study, I varied the CLKDEL, 
BCDEL, and B0DEL delay registers on a subset of XTC cards to study the 
effect how COT hits are classified (prompt, delayed, or prompt + delayed). 
 
For simplicity, we used the standard physics trigger table 
PHYSICS_0_01[43,207].  No CMX, silicon, or SVT for most of the 
runs. 
 
The following XTCs were affected: 
 
  b0cot05 07  ->  b0xft04 06   SL 1A,1B 
  b0cot05 14  ->  b0xft04 06   SL 3A,3B 
  b0cot05 13  ->  b0xft04 06   SL 3C,3D 
  b0cot15 13  ->  b0xft04 15   SL 4A,4B 
  b0cot15 12  ->  b0xft04 15   SL 4C,4D 
  b0cot16 18  ->  b0xft04 15   SL 4E    
                  b0xft04 16   SL 4A    
  b0cot15 05  ->  b0xft04 15   SL 2A,2B 
  b0cot16 08  ->  b0xft04 15   SL 2C    
                  b0xft04 16   SL 2A    
 
  b0cot00 08  ->  b0xft00 10   SL 3A,3B 
  b0cot00 07  ->  b0xft00 10   SL 3C,3D 
  b0cot00 15  ->  b0xft00 10   SL 1A,1B 
 
The register settings for these XTCs were varied simultaneously. 
All others XTCs remained at the default timing. 
 
The default settings for CLKDEL, BCDEL, and B0DEL are:  0x2E, 0x1E, 0xBE. 
All three delay registers were varied so that the relative differences    
between them remained the same. 
 
Runs 128458 to 128466 correspond to the XTC timing scans. 
 
The following runs were taken: 
 
   CLKDEL = 0x3D   Run # 128458 (*) 
   CLKDEL = 0x3D   Run # 128459    		52449 L3 Accepts 
   CLKDEL = 0x1F   Run # 128460    		26673 L3 Accepts 
   CLKDEL = 0x24   Run # 128461    		29056 L3 Accepts 
   CLKDEL = 0x29   Run # 128462    		28997 L3 Accepts 
   CLKDEL = 0x33   Run # 128463    		45410 L3 Accepts 
   CLKDEL = 0x38   Run # 128464    		26258 L3 Accepts 
   CLKDEL = 0x47   Run # 128465    		30009 L3 Accepts 
   CLKDEL = 0x10   Run # 128466    		26250 L3 Accepts 
 
(*) Run 128458 was ended prematurely due to excessive silicon busy timeouts. 
    Silicon and SVT were removed for subsequent runs. 
 
Trigmon was the most useful real-time diagnostic tool.  In particular, I 
watched the TDC pulse start times for b0cot05 slot 07. The distributions of 
start times for prompt, delayed, and prompt + delayed changed noticeably for 
each run.  Some observations: 
 
   1) When CLKDEL is shifted higher (say to 0x47), we accept some 
      additional delayed hits out on the tail (out to 420ns).  The 
      default value of CLKDEL (0x2E) clips off the tail at about 400ns. 
 
   2) The boundary between prompt hits and delayed hits shifts with 
      CLKDEL just as expected. 
 
   3) Here's a question for Ken.  On all of the runs, the first 
      prompt pulses show up at about 143ns!  For large values of 
      CLKDEL, I would have expected the first prompt hits to have 
      later start times, since the earlier possible pulses would  
      be arriving too early to be classified as prompt.  Does this 
      make sense? 
 
We should follow up by looking at the data offline!! 
There is a lot to learn. 
 
Special thanks to Michael Schmitt (Ace) and Maurizio Iori (CO) for 
their assistance.

choosed only files taken with physics trigger table (not cosmic 
or test tables)

 /cdf/code-common/cdfonline/errmon/log/daq  directory) 
 
efficiency and resolution are extracted from stream A look area

board 17 is b0xft04 slot 5 chips 1a and 1b, which is XTC in 
b0cot05 slot 8? 
 
Problem XTC that Jay talked about?  No apparent holes in track or 
segment occupancy, only in delayed hits and in track efficiency around 3 radians.</pre>

<pre>Also, SL6 fewer prompt hits in last octave - due to washer that
Dave Ambrose found?  It had the effect of increasing width and
there are more pd hits... These plots are from runs 128066,
128338 and 128342 stream A.</pre>

<pre>Tested two TDC boards in the clean room.  Both boards are from crate B0COT05.  We ran 100K events with 10 iterations. 
 
  1)  TDC613/57 (in slot7) passed the finder input capture test.    2)  TDC688/98 (in slot 8) failed (stuck bit).  Replaced with XTC20 and repeated the test.  Passed after the replacement.</pre>
