High losses ( > 30kHz). Pausing run, Vladimir has paged the general silicon pager and is putting the silicon HV on standby.

     Having the Silicon on STBY we got a trip alarm. "Software 
     protection trip High DVDD Current SVX B1 W10 L2.</pre>

<pre>Directed over phone by Auke Pieter we  reset trips,
ran ./cratematch.pl script, put SB1W5 on STBY, ran 
./cratematch.pl again, until sillicon was ready again.
Peaks in losses still high, every 5-10 sec around 40 KHz.
Unitl we get stable beam condintion, silicon will stay on stby,
and out of the run.</pre>

MCR not very optimistic about losses -> run without silicon

Now running stabily without silicon.

<pre>Should the hot stripe along the bottom half of the top 
two plots be in these Dirac Trigger Occupancy plots from 
TrigMon?  </pre>

Henry Frisch claims this is an XTRP problem...

<pre>This is the second time we have PHA crate 10 HV trip. 
It self-clears.</pre>

<pre>One  more PHA HV alarm THis time it is crate 6.</pre>

MCR reports they're done adjusting the tuning, and have pushed the collimators back. Losses now look stable, but are still slightly high ( ~25kHz ). We're going to watch the losses for a while. When we're comfortable, we'll bring up the silicon HV and start a new run with the complete system.

b0fib04 failed coldstart. Vladimir paged silicon general pager. We're coldstarting again, as per expert advice.

all of COT tripped during last flying wire.
<!-- Author: Nate -->


<!-- Date: Sun Sep 30 19:14:00 2001 -->
We were able to coldstart. However MCR called and reported that losses are growing ( they are now approching 40kHz ). They're going to try a new tack to reduce losses. In the meantime, we're removing silicon from the run config. Argh.

Paged SVT to let them know of the lack of prospect.

<pre>Tried to iclude silicon, but svx04 failed to ColdStart. 
Directed over phne by Auke Pieter, we turned off, STBY  svx wedge 4, and when we were ready to ColdStart again we got a call from MCR about the losses that started having peaks over 40KHz, sometimes over 60KHz.  Decided to put off silicon again. 
Partitioning w/o silicon.</pre>

Tried to start a new run, got repeated DTO's from b0l1cl00. Resetting this crate did not resolve the problem. Reset entire system, now running smoothly. 
 
We noticed in the error display, the message strongly reccomending we powercycle one of the event builder crates. Normally, this message comes in one of the orange pop-up windows. Since there were no EVB errors in the error display, we ignored this... 
 
...till we started to get error messages for b0eb15. We've powercycled this crate, are cleaning up EVB and will try to run again. 
 
We are bothered by the fact that there was no orange pop up window for this error.

    PEM trip crate6 trip, short afterwards COT superlayer 7 
    trip. Easy to recover. </pre>

(As in don't use [43,207])</pre>

<pre>Larry killed the "Icicle" program running on  
Solenoid2 for me.    This Slow Control recording  
program had been running over the weekend, and filled  
up the development MCS database files.</pre>

<font color=red>Shift Summary: </font><pre>Executive Psychotic Summary: 
 
Not bad for efficiency if you don't mind silicon being off due 
to high losses ("We're working on it"). Perhaps we need to 
give up on shooting straight.  Two track trigger board 
still problems. Usual litany of PEM/PHA self clearing complaints, 
mostly crate 6, some crate 10. And a TOF one. COT SL7 tripped a 
few times.  Heather might come in eventually.</pre>
