<pre>Took 70k _COSMICS, ~100 Hz after dropping (corrupt) silicon. 
Stopped to add back svt, not their fault.</pre>

<pre>Much work done behind the scenes on this.  Greg Veremendi
rebuilt development YMON with the CMU distributions back
in.  That let Yoshi and Justin run YMON offline on 
fcdfsgi2 and feed me the plots.  I looked at the plots
and, so far as I can tell, everything looks exactly as it
should.  (Although there is one noisy wedge again)

<pre>Had daq freeze up with no error message, ace consults Arnd, gets 
things to check if it happens again. 
Took 100k, l1 rate 110, l3 70? Investigating.</pre>

a couple notes: Arnd suggested a problem with either Fred
or b0tsi00. We will keep an eye on these crates in case
problem occurs again.

Also, we saw the rate out of the EVB/ into L3 vary drastically
during the run. Seems to be correlated with activity 
in the tevatron.
<!-- Comment: Sun Oct 29 18;42;55 comment by...Bill -->
uh oh, there seems to be some confusion. It was runs
102751 and 102752 which ended due to the mysterious 
freeze-up in DAQ. Run 102753 ended due to a DONE
timeout in L2 decision crate 00.
<!-- Comment: Sun Oct 29 21;32;17 comment by...Stephen Miller -->
<pre>Another possibility is the L2 processor. If event taking just
stops and HRR doesn't recover, then the L2 processor may have
crashed. Reset the L2 Alpha processor (top button on the board)
and then try HRR again. Keep track of the frequency of this
kind of error.</pre>

<pre>run 102754: 100K events, COMMISSIONING_COSMIC(1,67) 
 
 from the "fred prescale" page: 
   L12_Jet_2: 120 Hz 
   L1_Min_bias: 82 Hz 
   L1_zero_bias: 18 Hz 
   dimuons: 0.3 Hz

  L1A rate: 100Hz 
  L2A rate: 100 Hz

 from "EVB" display 
  rate out of EVB/(into L3): 80Hz 
 
 from L3 display 
  rate out of L3: 80 Hz 
 
We end this run so that Ivan can investigate why not all the 
L3 nodes are alive.</pre>

<pre>Ivan brought back all the L3 nodes that were not responding. 
Started run 102755, but it ended after only 4k events 
due to the mysterious DAQ problem. I power cycled 
b0tsi00 to see if that will help.</pre>

<pre>The L1cal and L2cal crates all seem to be behaving very  
strangely. None of them will respond at the partition stage. 
Rlogging into the crates reveals that none of the libraries 
are loaded! rebooting the crates does not help. Arnd 
has been called in and will look into the problem. In the 
mean time I am running with a zero bias trigger. Rate  
is about 2 hz at L1,L2,L3, there is no deadtime (if there 
was at 2Hz, then we would all be in a lot of trouble...)</pre>

<pre>MCR reports there will be a couple hours of no beam. If we 
could trigger it might be worth turning on COT but ... 
We can do CLC calibrations perhaps.</pre>
<!-- Author: Larry N. -->


<!-- Date: Sun Oct 29 20:59:19 2000 -->
<pre>run 102758 ended (1k evebts) due to a done timeout from cmu01. An 
investigation of the crateSet finds that we were not 
reading out in localDone mode, even though one of the  
TDC's is skipped in the bankSet. I changed to localDone, 
will try again. 
 
Mary also reports that the wrong half ladder was turned 
off  - preseumabley this happend sometime today (perhaps 
around noon?). She fixed this situation and we are adding 
svx back into the run.</pre>

<pre>ended run 102760 after 2k events. This was another low rate 
run with zero bias trigger (1,67). Saw no problems 
with either silicon or with cmu01.</pre>

<pre>The b0l1clNN and b0l2clNN crates failed to boot up correctly 
since the vxboot table files contained various products in 
private home diractories, and this home directory had been 
cleaned up, i.e. the products had been removed. 
 
I backed up the table files (diractest.table.bak and 
l2caltestb.table.bak), and removed all references to user home 
directories, as well as setup's for boards not present in these 
crates (Admem, testclock, Fred, ...). If any of these are needed, 
they have to be reinserted, but please not from another private 
version ...

<pre>Some quiet time in Tevatron, so we used this opportunity 
to do the CLC calibration (Alexei was paged, and was 
actually the one to do the calibration). So, CLC 
should be calibrated for the shot tomorrow.</pre>

<pre>Since we now have the L1 and L2 calorimeter crates back 
we will take a run with the full system. Run number 
is 102763, running with the COMMISSIONING_COSMIC(1,67) 
trigger table, non-myron. Rate is only 17 hz (L1,L2,L3).  
This is equal to the zero bias rate. We are getting 2 jet 
events at about 120 hz, but for some reason we 
do not get any of these events and they don't count 
in the rate (any speculation on 
why this is?). We still see no problem with silicon. We 
still have L2 processors, see no problem. We end the run after 
4627 events to switch to higher rate trigger.</pre>
<!-- Author: Bill Orejudos :: (run 102763) -->


<!-- Date: Sun Oct 29 23:42:38 2000 -->
<pre>Using COMMISSIONING_HIGH_RATE(1,67). L1A rate = L2 A rate = 
1.7 MHz. Rate out of EVB/into L3 = 140 Hz. Rate out 
of L3 = 140 Hz. Arnd noticed that b0cmx00 is slowing down 
rate due to a lot of noise from the TDC in slot 3. We 
end the run to remove this TDC from the bankSet.</pre>
<!-- Author: Bill Orejudos :: (run 102764) -->


<!-- Date: Sun Oct 29 23:49:29 2000 -->
<pre>With the TDC in slot 3 of b0cmx00 removed from the bankSet, 
the readout rate is 240 Hz. We still have the L2 processors 
in. Here are the stats: 
 
 L1A = 1.7 Mhz 
 L2A = 1.7 Mhz 
 rate out of EVB/into L3 = 240 Hz 
 rate out of L3 = 240 Hz 
 
The deadtime is close to 100% (since we use the high 
rate trigger). The "Readout Deadtime" us about 80%, the 
"Busy Deadtime" is about 20%. None is due to L2 (apart 
from the 1st few seconds of a run when the L2 executable 
is being loaded).</pre>

<pre>Just a note that we have not seen the mysterious DAQ 
freeze up since the TS crate was power cycled (and since 
Arnd fixed the L1/L2 cal crates, for that matter).</pre>
