The ACE called us because fib06 failed config. He did the usual procedure but the fib did not seem to come back fine. While trying to see the state of the fib, crate 13 had a communication failure. We recovered the crate by power by crate, but one of the wedges failed and had to be recovered after.

The L2Cal people were messing again with their tests at the end of the store. Because of the several changes in the configuration at some point the run configuration in RC seemed to be SHOT_SETUP with the silicon crates in, looking to the run looks a normal AAA_CURRENT. The SHOT_SETUP was picked but never applied <a href=http://www-cdfonline.fnal.gov/java/cdfdb/servlet/RunSummary?RUN_NUMBER=239974> 239974</a>.

ago </a>, DS 2293. I have looked at the currents from the ladders attached to the line  (f304, f310, f311, f312, f303) to exclude chip currents going crazy as a cause of this effect  and to prioritize what ladders to exclude in case of a trip. All AVDD and DVDD currents looks flat and stable. The bias currents of f310, f311, f312 are completely insensitive but the bias curents of  f304 and f303 show a ~ 10 % increase during the fluctuating period. I think this is an effect of the cooling flow dropping, not a cause. So it seems that the bubble/blocking theory is favoured. The best candidates to exclude from the database in case of a cooling trip are f304 first and f303 second.</td></tr></table>

<h3>Jennifer's Cooling Saga</h3> 
So, as requested by Del and Bill Noe, they wanted a sample of the ISL coolant to do a resin test to see what the affect of adding more resin could be. KC went ahead and removed ~5 gallons from ISL with *no* problems. Problems occurred when he tried to add back 5 gallons of water to replace what he removed, tripping off both East and West of ISL. Pooey. 
<p> 
Boy was that a mess. For some reason, each and every time I tried to re-establish flow I ended up tripping off both East and West. Wonderful. It must have been something for the PC lines (pressures?) but I couldn't even see it in our nifty FTrend plotter. So, it took me *quite a bit* of time in the freezer trying to re-establish flows. Jose had a good idea about adjusting the bypass EV valve to lower the chiller outlet pressure. This helped and I was only a few tries away from re-establishing flows so that we could make it into the store just at the nick of time. Thanks to Jose, Ignacio and our new Sebastian for the moral support and for sharing my pain. 
<p> 
To illustrate my disaster this evening, I've included a screen-shot of the real time plotter below...

<h3>Note to self...</h3> 
We should *not* mess around with anything cooling related if there will not be TeV studies. If there are any problems, we end up cutting it way too close. I am putting my pink foot down.

<h3> 5 ladders down</h3>
So we tried to keep ladders in the line but to no avail. The relevant entries the PS log are below.
When we saw the slope  we switch off  f304,f303 and wedge f31 (first peak). Then switch on wedge f31 and excluded f304 from database. At this point we started taking data. At  19:42 the iterlock tripped the bulkhead (second dip). We recover the wedge and excluded f303 in parallel. When we went above 23 C we excluded f311 and f312 hoping to leave at least one ladder in the line. However we had to exclude tha last ladder in the line f310 when we fluctuated to 23.5 C at 20:28. Now we are stable at 20.3 C. This must be room temperature in the ISL (that is the temperature for the other blocked line, C1.1).  We still have the hope of recovering some of this ladders since the flow in CE2.2 is slightly smaller (2.85 => 2.5). We'll give it a try when the store is dropped.

<h3> Svxinter and TevMon </h3> 
Before cooling trip, we tested with Dean the new version of the TevMon permit (silicon to standby automatically if TevMon is in alarm).  
<p>Dean fixed a problem with the CAENET and now code works without major complains. By doing on svxinter "BadBeamAllToStandby", the program checks the permit and the status of the ladders sending to standby the ones that are on. The automatic check is still not working but the only thing to do to have it working is to change the configuration file of the svxinter boot and reboot svxinter. 
 
<pre> 
/cdf/onln/code/cdfprod/caencontrol/v5b/examples/startup_rtlm 
</pre> 
 
<p>Dean still has to set the time between checks of the Permit and fix a bug (it has problems when you have a mixing of ladders on and standby). A test with the full silicon ON must be done at the end of the next store. 
<p>In case this version of the code has problems, to go back to a working version follow the instructions in <a href=https://www-cdfonline.fnal.gov/cgi/internal/elog/det-system-elog.pl?nb=silicon&action=copyentry&page=345&time=19:36:24>e-log</a>

<!-- Comment: Thu Apr 26 13;32;32 comment by...Dean -->
<pre>For clarification, "BadBeamAllToStandby" doesn't check the permit signal.  that is checked elsewhere.  The timing and BeamMonitor startup script are done just need to be added to the online version once L00 is fully tested with this.  Should be a 2 minute job.</pre>

I asked the ACEs to have a look to CCE2.2 and they are doing it. They paged me because there has been a sudden jump in the temperature from 20 C to 12 C. If it holds maybe we will be able to reinclude back some ladders.

Last week we noticed that in run number 239256 there were no data for SVX in ADCmon(see  
<a href= '/cgi/elog/det-system-elog.pl?nb=silicon&action=view&page=349&frame=2&anchor=08:50:28'>

We have checked this run and the corresponding SVXmon data and everything seems correct. This suggests that the problem may be related to ADCmon. We will have to work on this.

I tried to reset the VRB, but that confused the reformatter and  we had to restart the run to fix the problem. Some messages continued appearing (we were not even in config) when we tried to restart the run so the ACE cleaned the EVB. But, the cleanup did not finish properly. It took us a while to realize of that, then it was re-done properly and we started running. Now everything looks fine.

<h4>...as if coming in by 6am wasn't enough...</h4> 
...the not-so-friendly svxiicon iFix PC called me in a bit earlier. Apparently, "almost-2-week" reboots aren't good enough and if you're off by a couple of days, iFix gets back at you for your lack of scheduling by crashing to a point of no return. 
<p> 
The PC wasn't completely hung--our 3 processes were still publishing data--only iFix was. Aside from the obnoxious window with the smiling guy, no other windows were open. The workspace (or any other windows for that matter) could not be opened because of lack of memory. I couldn't even log in as I was not permitted "due to security". Whatever. I closed our 3 .exe's and  with some guidance from Dear Post Doc (who's breakfast I interrupted) I rebooted the PC "the Ankush way" by pushing the button.  
<p> 
Everything came back fine. 
<p> 
NOTE TO SELF: reboot the pc in t minus 14 days.

<h3>The Great Interlock Code Change</h3> 
For the most part, we started on time this morning. The detector was switched off and flows were tripped off in accordance to our procedure. Ulrich and I began with a data window with all the words and variables that we would need to fiddle with, and we also had the PLC ladder code open. We began to follow out TWiki procedure, but realized that we were running into problems with the logic. Our new "freeze protection" trip coils were being set incorrectly and we believe that it was a misunderstanding of how the "not" logic works. More details about that to come in Ulrich's addition, and in the <a href="http://b0sili01.fnal.gov/cgi-bin/TWiki/bin/view/Silicon/InterlockCodeChange">Silly Twiki</a>. 
<p> 
Once we established the proper procedure for setting our trip coils the rest of the procedure and validation ran very smoothly. After validation, Ulrich worked on improving our iFix pages and I re-established flows to the detector! <b>Flows were re-established without ANY tripping! Go Me!</b>. 
<p> 
Currently, the detector is coming back up and chiller setpoints will be changed soon.

SVX is now back to it's favorite -10°C.

<!-- Comment: Thu Apr 26 10;49;28 comment by...Ulrich -->
<h3>Freeze Protection Interlock</h3>
Today we have implemented a SVX portcard freeze protection interlock. The logic of this interlock will trip the flows to all SVX bulkheads  if the temperature of any SVX portcard line is below 0.5°C (unless that temperature reading is fake and comes from an open RTD sensor). This change became necessary because we decided to remove the glycol from the ISL cooling circuit, making the SVX portcards lines vulnerable in terms of freezing by the ambient temperature. The details can be found in the above-mentioned TWiki page. The programming and validation went fairly smoothly, except for the following two problems:
<ul>
<li>We could not get Andy's proposal for using the Bit Pick (BITP) command to test the "Open RTD" bits running. As Jennifer already mentioned, the problem seemed to lie in combining several parallel NOT statements. So we fell back to my previous proposal of copying the "Open RTD" bits into coils (with the obvious disadvantage of allocating more coils).</li>
<li>
We tripped the flow to the full detector during the validation. For simplicity we forced the raw temperature readings to 0 (-200°C), which triggered a dew-point trip.
</li>
</ul>
Thanks to everybody for their input to the discussion: Peter, Mary, Jose, Ignacio, Jennifer, and especially Andy!
<!-- Comment: Thu Apr 26 14;53;16 comment by...Ulrich -->
Just walked by the chillers to see how they are doing. My subjective impression was that the SVX chiller was in "cooling" for a longer time than in "hot gas". Could be that the chiller takes a while to get accustomed to the new set point. Could also be that the chiller is low on freon and needs to be re-charged soon Let's keep an eye on it.
<p>
Another remark: during the cooldown, I have changed the e-valve setting for BHW1 from 80% to 75% because the pressure was kind of high.

<pre>Made the test for VRB 159, after 40 millon loops there was no error, then Andrew Ivanov by mitake kicked the power cable of the computer and turned it off, since there were no errors in the  
Fib2Vrb test after 40 000 000 loops will consider VRB159 to be  
good. 
 
I have starter a 40 000 000 loop test for VRB 151 now, 
should take some hours to finish the test.  </pre>

We tried this morning before switching Off the detector the svxinter function <i>BadBeamAllToStandby</i> to put the detector to Standby. The beam was good so we had to force TevMon to be in Alarm. We did so by forcing one of the variables of TevMon to be bad. This worked and the permit went to alarm. We tried the function several times but it did not work. We need further investigation/testing from the programming side.

We had a strange episode today with b0dasvx01 monitor. Suddenly, it went off. We checked the connections and everything was fine and nobody was touching the computer... just by pressing the On button it came back fine again.  
<br>This is the first time that I see a spontaneous switch off in a monitor. Could be that CAEN crates infected our monitor?

They had to restart the run due to insert L2 crates. The new run came with SVX Bank corrupted. I asked the ACE to restart the run. This is starting to be annoying it is becoming more and more frequent.

<h3>PS swap of SB4W4</h3> 
We had the chance of a 2hr access, so we decided to swap one of the SVX supplies with drooping DVDD and AVDD voltages.  We picked SB4W4 since it had several badly drooping channels, and it was on the East side (the COT work on the West side required moving out the steel).  Everything went <i>almost</i> perfectly; we swapped in one of the new SVX supplies from CAEN, but halfway through the loadbox test realized that the high voltage trip limits had not been set; they were at the maximum of 250V.  Also the DVDD and AVDD voltages were set lower than the nominal.  So we pulled the supply, brought it upstairs, quickly changed the limits, then took it back down to complete the loadbox test.  The supply is now hooked up to SB4W4, it's biased and runs fine.<br>

We were testing BadBeamAllToStandby (sends everything to standby) during quiet time today. Dean  removed a function call that was not behaving as expected and checked extensively the behaviour. Because of this we noticed that short communication glitches happened 1 out 10 times we called the function. We decreased the wait time between 
calls  by a factor of 10 (increasing it made things worse), which seems to work somewhat better. With the latest timing we did not get a glitch for  45 calls.  The theory is that BadBeamAllToStandby and  the PSGui collision when reading the data  from the crates through CAENNET. Dean will set a variable to inhibit (or delay) the PSGui to refresh if BadBeamAllToStandby  is reading the voltages. We  left a proccess running in svxinter (BeamPermit) that calls the function every 2 minutes during shot setup. Now is not running.  (BTW PSGUI is back running in b0svx01.)

<h3> VRB swap </h3> 
We have swap the VRB on b0svx07 slot 19 (wedge f32). We tried reseating it but the seemed misalignment with the neighbor VRB did not disappear so we decided trying with another VRB (VRB 150 tested yesterday). The alignment it is still not perfect but looks a little bit better.  
<p>After the swap we tried several cosmics runs, starting and ending. We did not see any problem with that VRB.

 Ladder SB0W7L1 kept tripping on DVDD overcurrent. I thought that this was one of the ladders that was giving some problems last month (<i>same wedge wrong ladder</i>) and I took out the ladder from the DB (remotely). After guiding the ACE to change things in the PSGUI and RC we tried to run without the ladder, but we had some problems running. 
 
<p> I came in and had a look to the PSGUI. Everything was properly done but the ladder was tripping even when OFF. Then I hockerized the crate (6) and put back the ladder. After that we could power back all the ladders and resume data taking with silicon. 
 
<br><b> I should have asked for a hockerization before taking out the ladder of the DB...</b>

<h3> SVX trip </h3> 
The alphanumeric pager went off around 14:20 because a SVX trip. I checked remotely the screens of the silicon monitors and I saw all SVX completely tripped but the DOIMs on, ISL and L00 looked fine.  
<br>I run into the control room and they paged me while driving in. The cooling is fine (not a cooling trip) and all the ladders had tripped for DVDD overcurrent. I put the silicon to standby and changed the set point of SVX to -6 C (some of the PC lines were at 1.4 C but just in case). 
<br> The clock look good and the MCR has made nothing with the LLRF. It seems more likely a problem with b0svx02 (SRC) but in the LA is running and nothing has triggered and error. We have gone to end of store mode (14:45) and we are going to shot setup. 
<br> I put one wedge to standby and it is holding and everything looks fine.

<!-- Comment: Sat Apr 28 15;46;48 comment by...Jose -->
Looking into the log files and LA nothing seems to be bad in the SVX SRC. After a while with one wedge on, I started to power up the detector when the tsi went bad. Could it be related with the previous trip?

<!-- Comment: Sat Apr 28 16;50;29 comment by...Ulrich -->
We had two such incidents in one week early January (<a href="http://www-cdfonline.fnal.gov/cgi/elog/det-system-elog.pl?nb=silicon&action=view&page=334&frame=2&anchor=05:11:23">here</a> and <a href=
'http://www-cdfonline.fnal.gov/cgi/elog/det-system-elog.pl?nb=silicon&action=view&page=335&frame=2&anchor=16:08:23'>
here</a>). The symptoms were exactly the same as today. We suspected a glitch in the SRC, and Mark added new logic to the LA to find gaps in the chip command bit stream. I couldn't locate any TSI problems at that point in time. What does the Old Yale say?

That's interesting. On January 8, there were also COT_18 problems before the Silicon trip, see <a href=
'http://www-cdfonline.fnal.gov/cgi/elog/elog.pl?nb=2007&action=view&page=22&frame=2&anchor=01:28:15.080'>
here</a>. Not sure how they could be related.
<!-- Comment: Sun Apr 29 13;08;10 comment by...Ankush -->
<p>Another theory is this could have been a short clock glitch....this has happened before...the glitch is short and so it is not seen by the CDF clock and none of the other systems are as sensitive. Empirical evidence has shown SVX is little more sensitive compared to ISL/L00 for clock glitches.</p> 

<p>As we now know how to use the VB interface for the logic analyser, one could consider writing a "clock glitch" trigger for the LA.</p>

Was the alignment checked when the detector was warmed to -6C ?

that could be the problem in this case... I do not think the alignment was changed.

<h3> ADC Monitering Summary (Run239900-240115) </h3> 
I have checked ADCMon plots during this week from run239900 to 240115. 
<br> 
I will report the ladders which have a issue and intersting work.  
The other ladders look fine.
