Forgot to make an entry last night about my tests.  I came in around 10:30 to work on CLIST sync errors.  The first hour of my work was spent doing really stupid stuff I should know better about (ie the backplane needs to be jumpered in de00 if a board isn't plugged into the front).  The second hour I didn't see any errors - but the rates were very slow; I need upwards of 1M events to reproduce this error.  High deadtimes from TSI.  Consulting with Frank and Jim P about this.

also - I couldn't get L3M to pass ColdStart.  I just ended up removing it from my run.



<!-- Date: Thu Sep 6 09:15:36 2001 -->
<pre>Took several runs with myself, Boris, and Frank, to determine source of high TSI deadtime for the L2 tests I had been running the past few days. 
 
These runs were taken with CCAL, WCAL, PCAL, L1CAL, L1GL, L2CAL, L2GL, TS, HEVB, alpha in cutting mode and tagging mode, Physics_0_01[24,174], changing Jet5 prescale from 20 to 2, L3M removed (takes very long time in coldstart).  The debug messages were NOT turned on for l2.  (ie the deadtime can't be attributed to that) 
 
We see the deadtime accumulate in TSI when we put the alpha into cutting mode.  Found EVB buffers almost full.  Adding more L3 farms gives a higher L1A/L2A rate, but we still see large TSI deadtime.   
 
Frank is going to consult with Jim and Greg, and we'll work on this later when L2 takes the system for tests.</pre>

<pre>First Run : 

3 L3 subfarms (3 outputs)
L3 Input 145 Hz 25 Pending events in EVB 

Total Deadtime 70% 
- Busy 50% 
- Readout 20% 
- TSI 30% 

Level3 is blue. Busy deadtime due to insufficient 
number of converters. 

Second Run: 
6 subfarms (4 outputs) 
L3Input 290 Hz 9 pending events in EVB 

Total Deadtime 50%
- Busy 0% 
- Readout 64%
- TSI 35%


</pre>

<pre>Talked to Ilya about TSI deadtime. 

Wa can have a maximum of 7 events suspended in VRB 
while TM is waiting for SM. If this number is 7 
(corresponds to 27 events pending in EVB) TSI stops 
sending triggers to SM. That cause TSI deadtime. 

This is disagree with the second run. We had 9 pending
events pending in EVB. I had to run it again to be sure that 
my readings is correct.

<pre>J.C. Yun updated database for iFix. 
No heartbeat from CEM, CHA, WHA and GAM.   
Nikolay should be here shortly.   
Meantime, we are having flying wire</pre>

<!-- Date: Thu Sep 6 10:12:47 2001 -->
<pre>As COT HV was coming up after flying wire,  Layer 4 tripped. 
Puting COT HV up, and start runing. 
GAM, CEM, CHA, WHA are coming up, as Nikolay restarted them. 
Nikolay claims that there was nothing wrong with HV of the above detectors, as he could see it from PisaBox, but that there is a bug in the monitoring program that has been know for some time, 
and that it has been worked on. 
Meantime, Boris has started the run.</pre>

<pre>Took short run for Level3. Watching for Pending events and  
TSI deadtime. When we have TSI deadtime, we have 25 pending events. Everything is consistent.  
  
Silicon is back.  
 
Give system to Level2 people. </pre>

We seem to be having a reoccurence of the problems we experienced before with temperatures in the collision hall and losses in the CLC (C:LOSTP and C:LOSTPB).  On a fine scale, there are frequent peaks above the SVX/COT limit of 20K.  Looking at the lumberjack history, it appears we have had to recent occurences of this, one between 10:30 AM and 11:30 AM this morning, and another right now from about 12:30 PM.  These nicely follow the curves for the the AC2 chilled water temperature.  I'll talk to Rob Roser about looking into this.

Due to unstable loss conditions, turned SVX to 
STBY.  SVX is OK to integrate into CDF if losses 
stabilize.

These are xx=UV, DV, UH, DH  for upstream (p), downstream (pbar), horizontal, and  vertical.  We do not see anything in iFIX moving since 0800  except the outside air temp which has been steadily rising since then from about 65 F to 90 F now.</a></td></tr></table>

<pre>COT cooling alarm.  It went off by itself. 
Steve from Cryo System called.  SUVA alarms, level went to 0.8 
that cuased pump to shut off. 
 
Meantime, we are not runing.  The last spike in losses was noted 
2-3 minutes ago.  I am puting all the systems on STBY.  TOF off.</pre>
