<pre>Finally started a run again, but COT is off, SL1 tripped 
about 15 min. ago. Expert notified.  
 
event builder statistics showed no events getting to evb 
First we rebooted the RXP crate, but we still saw same problem 
We rebooted the TS, Trigger Cross point crate, this seemed to 
fix the problem. 
 
Noticed that the COT HV back on, stopping run with 27k events 
and starting again with COT HV on. </pre>

<pre>b0cot04 gave a done timeout. 
No error message though. 
Log into crate and see many FISIONslave tasks.... 
Accidentally click HALT from a PAUSED state, 
this causes Level 3 to go into an ERROR state.... 
Reboot b0cot04 and try again</pre>

<pre>Counted the truncation errors on the COT:

cot13:3
cot17:6
cot18:2</pre>
<!-- Comment: Tue Oct 31 10;48;21 comment by...Arnd -->
<pre>'9 errors' means in reality '9 or more errors'. The readout code
will then stop reporting these errors, and only send back one in
500 to run control from that point on.

myron level1 early mode, for Steve Nahn

<pre>forgot to hit enter when running cotdac script!!!
Also we are running to 80k events since it's myron mode
Steve also requested that we not end, but halt so
he can check some things.</pre>

<pre>Steve seemed happy, but then again, he always seems happy.
We stopped run. Waiting for further instructions...</pre>

We are going to begin SVX timing studies...


<!-- Date: Tue Oct 31 10:25:41 2000 -->
<pre>timing scan for SVX: the default timing on the  
SRC clock fanout is: setting 0A=5, 1A=8, 2A=8, 3A=8, 
0B=7, in units of 1ns). 
 
We moved 0A-3A and 0B (but not 1B!) by 7ns, and nothing 
worked.  Stephen Bailey (who was watching the SRC's LA) says 
that we were missing clocks. 
 
 
 
     38 ns + 7ns  no events so do a halt and adjust  
                  the timing back. to 5 8 8 7</pre>

Since it did not work, we reverted to defaults.
<!-- Date: Tue Oct 31 10:34:51 2000 -->
<pre>We changed the RF_Delay to 3*19ns. 
</pre>
<!-- Author: Petar :: (run 102868) -->
<!-- Comment: Tue Oct 31 10;38;05 comment by...Petar -->
This means that we changed the "Shifted BX" box
on the SRC to 11-10-100 binary = 116 decimal. 


<!-- Date: Tue Oct 31 10:47:52 2000 -->
<p>CMX HV trip, wedge 21. Reset. 
<p>
<!-- Author: Steve T -->
<!-- Comment: Tue Oct 31 11;29;27 comment by...Steve T -->
At about 11 we released the SVX readout so that stand-alone SOC tests could go ahead.

<!-- Date: Tue Oct 31 11:12:17 2000 -->
<pre>I calibrated the signal going to the visual scalar by comparing to C:B0TLUM.  The answer is 42.8.  That is the effective total cross section of the CLC trigger (in mb).  (Take this number with a grain of salt.)  I reset the NIM prescaler module in 1RR27D to 43, so the scaler is now reading approximately mb^{-1}.  However, this calibration may not be good for luminosities very different from the current value 2e29.</pre>

about 36k myron mode l1 early events

<!-- Author: Greg V. :: (run 102878) -->
<!-- Comment: Tue Oct 31 13;46;47 comment by...Petar -->
Prior to run 102878, the SRC maintenance crew were again
playing with the B0 fanout.  Previously, we were moving all
lines except 1B line, but that turned out to be our BC',
and no wonder that did not work.

First thing we checked (using the standalone svxdaq) that
aligning all six lines (0A-1B) is not a problem.  Then
we moved them from all six being 8, to all six being 0.

Run 102878 was taken with all six fanout lines being set to 0!



<!-- Comment: Fri Nov 17 20;05;04 comment by...Petar -->
<pre>According to our latest convention, this means that 
this run has been taken with the RF_Delay = 31 ns.
(38 - 7 by moving RF clock from 0x7 to 0x0).

(I apologize for not removing the default text first!)

This run was taken with:

- all six SRC clock fanout set to 0 (delay of -5 ns wrt usual)
- RF_Delay = 2*19ns
- BW = 4, Th = 5, DPS on and everything else as usual
<!-- Date: Tue Oct 31 14:08:59 2000 -->

<pre>Silicon-wise, this run was taken with:

- RF_Delay = 1*19ns (this changed)
- all six SRC clock fanout knobs still set to 0
- BW = 4,  Th = 5, DPS on and everything else as usual

<p>HV trip for CMX (wedge 21 again). Reset.<p>
<!-- Author: Steve T -->
<!-- Comment: Tue Oct 31 14;36;33 comment by...Steve T -->
Could not ramp CMX HV; it trips again. Tried three times, no good. Paging expert...
<!-- Comment: Tue Oct 31 15;01;44 comment by...Steve T -->
Abe Gallas put wedge 21 HV of the CMX on standby and ramped up all the rest.
<!-- Date: Tue Oct 31 14:29:49 2000 -->
<pre>Jean, Matt H. and I (Petar) decided that RF_Delay=38ns is 
more optimal than 19ns, and that indeed a small shift further 
might be in order. 
 
So I moved all six SRC clock fanout knobs to F (!!!) and 
we will keep using the default of 38ns, but with the addition 
of 8-10ns (since the previous default did not have all knobs 
on the same position). 
 
We will keep this as a new default, so from now all runs 
will use this until further notice! 
</pre>

<!-- Comment: Tue Oct 31 14;46;11 comment by...Petar -->
For some reason, FFFF+FF did not work -- none of the FIBs
initialized!  (We've to check with Steve Chappa about Fs)

Switched everything to DDDD+DD, and that work.  So we'll
use that, in conjunction with RF_Delay = 38ns.




<!-- Comment: Fri Nov 17 20;07;23 comment by...Petar -->
Actually, DDDD+DD did not work either, so for safety
we put it at BBBB+BB.  So, according to the latest
protocol, RF_Delay = 38 ns + (0xB-0x7) = 42 ns.

<!-- Date: Tue Oct 31 15:06:50 2000 -->
<pre>CMX NW21 Sense tripped at about 14:45.  A. Gallas came over.  Cannot reset.  Set this wedge off.  Rest of detector is up.  Note that NW02,03 ramps at 20V/sec instead of nominal 50V/sec.  Don't know why.  Abraham will investigate the problem with 21W. 
 
Today's note of CDF history is that 21W was the first CMX wedge we installed. </pre>

Restarted CSL. There were 16 connections to the CSL, which is
