Cryo will be testing the vacuum pumps; Tom is on his way over
<!-- Author: Mark -->
<!-- Comment: Tue Jul 15 10;50;03 comment by...SashaS -->
SVX chiller inlet pressure (SVX_PT_CHRET) is on high waring limit (4.9-5), SVX air separator level (SVX_LT_AIRSEP) is on low warning limit (19-20).

<!-- Comment: Tue Jul 15 11;12;48 comment by...SashaS -->
After test of spare vacuum pumps today, the SVX pump #2 (which we were running as the main pump for few months) came back with 0.4 psi higher pressure than before test. Tom asked cryo tech (Jim L.) to switch to the spare pump (pump #1) Meanwhile, KC will re-build pump #2.

Cooling trip, whole detector went down. Tom is on his way over. MCR just finished loading pbars...
<!-- Author: Mark -->
<!-- Comment: Tue Jul 15 14;16;38 comment by...Mark -->
It seems there is a leak in ISL vacuum pump #1, which just tested OK 4 hours ago. Also, for some reason, the valve to pump #2 kept cycling open and closed, so the pressure stayed high. The cryo guys manually shut down pump 1, so now pump #2 is lowering the pressures. Ace started a AAA_NOSILICON run while we finish recovering this.

Adjusting BIAS limits for ISL, due to higher temps after the cooling trip: BIAS0 - f200, f201, f202, f203, f204, f223, f310, f303, f304, f513, f120, f101, f102, f103, f104, f112, f113, f122, f123, f302, f003, f011, f013, f014, f021, f023; BIAS1 - f303.

<h3> Vacuum Pump test </h2> 
Jim Loskot did the monthly vacuum pump test this morning, at about 10:30 AM.  The ISL spare pump ran fine, but the SVX test showed a problem.  We had been running on SVX vacuum pump #2 as our main pump, which held less than 2 PSI of vacuum, and switched it to pump #1, which also worked well.  Switching back to pump 2 after the test finished however raised the SVX air separator's pressure up to 2.4 PSI.  We switched back to SVX pump #1 and asked Bill to ask KC to swap out SVX pump #2.
<!-- Author: Tom Junk, Jim Loskot -->


<!-- Date: Tue Jul 15 16:54:05 2008 -->
<h2>Cooling Trip</h2> 
At about 1:45 PM, the ISL flows tripped off.  The root cause was a leak in the polyflow tube from the vacuum pump near the vacuum gauge.  The pressure in the ISL air separator got up to 3.5 PSI, and the PLC logic decided to switch on both vacuum pumps and open the valves for both of them to the air separator.  We were better off switching just to the pump without the leak.  We should review this logic in the PLC (possibly if the vacuum is too high in the air separator, to switch pumps, leave it there for a bit, and see if it goes down.  Of course we could have a problem in both pumps..). 
<p> 
We recovered flows, using the  
<a href= 
'/cgi/elog/det-system-elog.pl?nb=silicon&action=view&page=400&frame=2&anchor=05:35:59'>older flows from April as a guide</a>.  The ISL CCE1 flow is a bit lower at the same valve setting (fluctuates around 1.6 lpm) as before, and I was loathe to play with CCE1's flow too much as we had just started a store and wanted to get data taken.  It turns out we had COT HV problems and did not lose any data-taking time due to this.  Flows recovered remarkably easily and temperatures remained stable after power was switched on.  We only tweaked flows a little bit, gingerly adjusting the valves to keep from tripping everything off while running.

<pre>iFIX SIGNS program crashes:  An additional instance of iFIX is running on another computer in order to maintain the solenoid status page (black box with green lettering).  Thanks to Mark Knapp for moving this display from VNODE02 onto another computer -- VNODE02's iFIX works much faster now (it still seizes up, but for much shorter intervals!). 
 
Anyhow, the workspace servicing the SIGNS crashed, with several iFIX internal error dialog boxes.  I acknowledged them, and the workspace disappeared.  Jim Loskot shut down iFIX and we tried to restart it, but the computer had run out of (memory? some kind of quota?) and we rebooted it.  The workspace came up after reboot but crashed again right away, and I rebooted it again, and the workspace crashed again.  I left iFIX running and restarted the workspace from the program icon in C:\Dynamics.  It's now running, and Jim Loskot will let Mark Knapp know about it in the morning.</pre>

Got paged by the SciCo that the COT SL2 is masked off in XFT due 
to more than 8 contiguous dead cells and that we may expect 
high L1 rates due to this. Since the COT data is being marked bad, 
I okeyed to bring silicon to standby. 
<p>The COT problem seems to be a grave one. If the experts figure 
out the offending wire (from analyzing lookarea data) and are able  
to single out a small enough group of wires we have a possibility  
to include silicon later in this store. Otherwise we will have to 
wait till this problem is fixed in an access. 
<p>It's a pity that this could have been a record data taking 
store!

<h3>ISL CCE3 Low flow</h3> 
 
Got some automatic warnings saying ISL CCE3's flow was below the warning threshold (1.7 lpm).  It has been changing slightly over the last day -- we had left it at 2.2 lpm with its valve 50% open yesterday.  It dropped to 2.0 lpm at midnight, and dropped again to 1.75 lpm at 2:45 PM today, and became a bit erratic.  I opened the valve to 59% and restored the flow to 2.5 lpm.  Hopefully this will stay.  The valve is a bit sticky (at 58 percent, we still had 2.7 lpm).

Store was terminated around 0830 this morning
<!-- Date: Thu Jul 17 04:34:00 2008 -->
COT guys weren't able to identify the offending wire in SL2, but they masked off quadrant A of SL2, rather than the entire SL2. So, we put silicon in for this store, but are keeping an eye on L1A rates to make sure they don't go too high. So far everything looks good

<ul>
<li>Known unfixable problem with low bit 6
<li>Very low occupancy and amplitude from Z-side

It took a while for these ladders to return to their normal currents. Since they were close to their limits anyway and the prescale-related current jump was small, I increased the Bias limits for those ladders.

PS #6 autohocker at end of store. SAR says it failed to recover, but everything looks good. And, there was an AVDD pinky in SB1W8L4 after that wedge recovered. I hockerized again (SAR failed again), but the pinky recovered. I then did a COLDSTART to make sure PS#6 recovered successfully, which it did.
<!-- Author: Mark -->
<!-- Comment: Fri Jul 18 10;56;51 comment by...Satyajit -->
If the pinky is due to a jump in current it is usually fixed by an
HRR. Hockerizations are needed if we suspect there is a corrupt
readback.
<!-- Comment: Fri Jul 18 11;13;58 comment by...Mark -->
We were at EOS so there was no harm in hockerizing again
<!-- Date: Fri Jul 18 08:41:57 2008 -->
I hockerized crate #8, due to the pinky last night showing 0 Bias.
<!-- Author: Mark -->
<!-- Comment: Fri Jul 18 08;43;18 comment by...Mark -->
Whoops, that was the wrong crate. Now I hockerized crate #1, which had the pinky (SB2W1L0)

There were some changes to L2, which were updated in a lot of run configurations, but not D-mode calibrations. So, when doing a D-mode, the Aces need to be sure to use the proper run configuration.

The CO 
<a href=
'/cgi/elog/elog.pl?nb=2008&action=view&page=602&frame=2&anchor=10:03:44.493'>
reported a red block</a> in SVXMon cell ID map. On checking I
see that the ladder SB2W4L4 has a long history of stuck cell ID 
and other bit errors. The ADC plot shows clear signs of bit errors. 
We could try power cycling this wedge but it is not likely to 
help.



<!-- Comment: Sat Jul 19 16;51;17 comment by...Satyajit -->
After a power cycle some chips on the phi side seem to have 
recovered from stuck cell ID problem. May be this is all we
can expect to get from this ladder!

to ~ 26.6 kHz (significantly below 35 kHz) before the handbrake  
kicked in. We resumed to receive another immediate handbrake. On 
checking I saw a burst of DPS changes right before RC went to 
halt. The ACE shepherded b0tsi03 and restarted the run. About 15 
mins into the Run the handbrake fired again right after another  
burst of DPS changes. I asked the ACE to take silicon out until  
trigger experts bring L1A rate under control.

Got paged for an AVDD pinky in SB0W3L3, current dropped to 0. Tried HRR and power cycle, no success. Ignored for now, will hockerize crate at EOS

Another pinky ~1 hour ago in SB0W3L2, AVDD jumped above the limit. I talked the SciCo thru hockerizing the PS crate, while they were halted due to a plug HV problem (Ace was busy dealing with that)

One hour into the store there was a

'/cgi/elog/elog.pl?nb=2008&action=view&page=606&frame=2&anchor=20:14:15.335'>
DVDD pinkie in ISL B3W2L3</a>.
A hockerization of PS crate #15 fixed it.

The ISL coolant is at its low warning level (20 inches, which is still plenty of coolant), and is just beginning to send iFIX warnings in e-mail.  We will have more coolant (water) added tomorrow during the access.

I've noticed that the AN pager is getting a bit flaky lately - pages seem to be taking longer to go through (the latest one took ~20 minutes), some pages don't seem to be going through at all, and most of the pages' messages are garbled in some way at least a little bit. Perhaps it just needs new batteries?

Think a new battery was all it needed

<font size="3"> <h3> ADC Monitoring Summary (Run264700-264883) </h3> I have checked ADCMon plots during this week from run264700 to 264883. <BR> 
Ladder f533, suspicios from the last shift (unstable Bit Error) seems to work fine this week. Other issues:

Ladder e004 is losing all the data on the Z side for the last runs, as reported by the MPC.

<pre>Flow rate before flow trip on July 16: 11.64 SCFH/Hr.  O2 fraction: 11.24%.  Flow rate after the trip: 14.41 SCFH/Hr, O2 fraction: 10.45%.</pre>

ISL_DPT CCE3 is a bit higher for the same flow rate compared with our April 13 reference.  We had to increase the CCE3 valve position to restore flows to the April 13 values, but the PCOT on CCE3 is a bit higher than before.  Now: 12.3 PSIA, then:  10.9 PSIA.  The DPT for CCE3 now is 8.3 PSID for a flow of 2.4 LPM, and in April it was 7.4 PSID and a flow of 2.2 LPM.  Since the pressure drop is higher with a similar flow, it could be the extra leak is in this line.

<pre>Warmed up silicon starting at 6:45 AM in anticipation of the plug pull.  Turned off power at 7:40 AM for LOTO work.  Temperatures still slowly rising, but we should be in good shape for the dewpoints.  Bob Wagner says he will take care of the N2 flows.</pre>
