<p>Store 4499 is still colliding, and as of 1705 hrs, the data 
   taking efficiency is 90%. About 2 hours into the store, CMX 
    SE wedge 15 started having HV problems, but it did not cause 
    significant down time. At 1051 hrs, there was large 
    enough TeV 
    beam losses in AGIG2 and B0PACG so that the silicon was put 
    into standby for about 15 minutes. This was some unintended 
    consequence of <a href= 
'http://www-bd.fnal.gov/cgi-mach/machlog.pl?nb=tev05&action=view&page=422&anchor=103146'> 
   TeV work</a> to address the SVX integrated dose alarm we got 
   at the start of this store. Other than that, running has 
    been very smooth. This store is scheduled for termination 
    at 0100 hrs, 15Nov05. D0 will go in for a 1.5 hour 
    access, but it is not yet clear if we will do CMX access 
    work then. 
    There is lots of <a href= 
'http://www-bd.fnal.gov/cgi-mach/machlog.pl?nb=runco&action=view&page=523&anchor=131321'> 
    accelerator work</a> going on today and tomorrow, with no 
    pbar stacking. There should be a store in by 0600 hrs, 
    15Nov05.

<p>Store 4499 is terminated normally at 0102 hrs. We recorded  
   4.9 pb-1 at 90% efficiency. Running was smooth. There was a 
   0.6 hr down time at the end when the abort gap electronics 
   crate power supply tripped. It was recovered by power cycling. 
   We did not go in on an access. 
</p> 
<p>Store 4501 starts at 0647 with an initial luminosity of 
   134e30. The TeV group fixed the problem of the larger 
   than expected SVX radiation dose during the squeeze. However, 
   beam losses were again very high at the start, and remained 
   a problem until about 0845 hrs. The proton losses were 
   problematic because both its horizontal and vertical tunes  
   were off. The silicon was off for most of the time and the 
   CMP and CMX tripped during this period. After the beam 
   losses were under control, we turned everything on, and are 
   running smoothly. MI safety testing was done for most of the 
   day. An AP-2 vaccuum problem required an access to fix it, and 
   a consequence is that the stack and stash pbars had to be 
   dumped. Store 4501 is scheduled for termination at 0700 hrs, 
   16Nov05. The TeV will be down on Wednesday for <a href= 
'http://www-bd.fnal.gov/cgi-mach/machlog.pl?nb=runco&action=view&page=524&anchor=085752'> 
   safety testing.</a> 
   We will get collision hall and TeV tunnel access.

<p>Store 4501 is terminated normally at 0725 hrs. We recorded 2.9 pb-1 
   at 83% efficiency. We had lots of problems with TeV beam loss during 
   this store, another 2 hours down time during the second half. 
   There were two beam loss incidents: a) both the TeV orbit stablilization 
   program stopping and the D0 quad moving, and b) TeV RF TRF4 tripping 
   off. 
   TeV safety interlock testing began after the store was terminated. 
   This along with MI safety testing was completed about 1355 hrs. 
   There have been a series of accelerator problems that prevented 
   pbar production (along with not having any pbars). Stacking finally 
   resumed about 1730 hrs. There will be TeV studies during the evening 
   shift while pbars are being built up. There could be shot 
   setup sometime during the owl shift. 
</p> 
<p> 
We were in controlled access from 0855-1437 hrs, and TeV 
sector A-E access from 1236 hrs for about 3 hours. 
Access jobs: 
<ul> 
<li>Run IIb XFT upgrade: A set of optical fiber cables strung to 
    a COT crate. Not sure which one.</li> 
<li>CMX: SE wedge 15 HV distribution <a href= 
'/cgi/elog/elog.pl?nb=2005&action=view&page=959&frame=2&anchor=10:52:27.934'> 
    resegmented.</a></li> 
<li>Miniplug: Checked ADMEM trigger cable on east side to see if it is loose 
    and causing always on trigger bits. It was not loose. The problem was 
    finally traced to a <a href= 
'/cgi/elog/elog.pl?nb=2005&action=view&page=960&frame=2&anchor=17:45:00.228'> 
    bad connection</a> in the trigger cable upstairs. 
    </li> 
<li>TeV tunnel: Jim Volk recovered some HLS monitors near the CDF halo 
    counters, with help from Rick Tesarek.</li> 
<li>Silicon cooling: Replaced an air dryer in the pneumatic control system 
    in the chiller area (outside of hall). 
    This should fix some of the flakey behavior of the Si cooling system 
    when work is done on the chiller controls.</li> 
<li>Lots of other DAQ stuff: online database maintenance, DAQ PC and online 
    file server reboots for another part of the online file system move. 
    The CSL was the unfortunate victim this time.</li> 
</ul> 
EVB2 news: the L2A rate is now <a href= 
'/cgi/elog/elog.pl?nb=2005&action=view&page=957&frame=2&anchor=18:04:32.574'> 
850 Hz.</a>

Tevatron update: The B11 separator has a vaccuum leak. The
   optimistic scenario is 1 shift before beam. It could be much
   longer...


<!-- Date: Thu Nov 17 16:36:10 2005 -->
<p>No beam due to a series of problems with the Tevatron. The 
   B11 separator vaccuum problem was quickly fixed. After that, 
   there was a ground fault in the D0 Q2-4 power supply. This 
   was followed by a new B11 separator vaccuum leak. A TeV 
   tunnel access is in progress to find and fix this leak. 
   We are not making an access.  
   Meanwhile, pbar stacking and stashing continues, so when the 
   TeV is back, there should be a good store.

<p>Store 4506 starts at 0653 hrs, with an initial luminosity of 
   69e30. This is lower than expectations because of a MI RF 
   problem. Our startup was quick. However we took data for the 
   first 1.25 hrs with a "dead" b0ccal00 SMXR for wedge 2W CPR, 
   CES, and probably CCR. This was fixed by powercycing the 
   crate and recalibrating. After that, smooth running. This 
   store will be terminated at 2200 hrs, followed by 2 hours of 
   TeV studied, then shot setup.

<p>Weekend Report: 19-20 November 2005 
<ul> 
<li>Saturday: 19Nov05: Store 4506 was terminated normally at 2205 hrs, 18Nov05. 
   We recorded 1.5 pb-1 at 87% efficiency, with overall smooth running for most 
   of the store. Store 4508 starts at 0312 hrs, with an initial luminosity 
   of 140e30. This store was lost at 0930 hrs, due to a TeV B11H separator spark 
   that induced a TeV quench at D4, E1, F4, and D0 low betas. 
   No big operational problems for store 4508, however the data is bad: 
   the PEM 5W ADMEM broke -- 15V problem. We took a 2 hour access from 1152 hrs 
   and fixed the PEM 5W problem by replacing the ADMEM. Another D0 access and 
   TeV studies followed. 
   </li> 
<li>Sunday: 20Nov05: Store 4514 starts at 0259 hrs, with an initial luminosity 
    of 135e30. We had a decent startup. There was only one short 15 minute 
    down time at 0424 hrs: SVX crate 10 required Hockerization. Some trigger 
    table tests were also done at the end of the store. The store was normally 
    terminated at 0512 hrs, 21Nov05. We recorded 3.9 pb-1 at 92% efficiency: 
    a very good store!</li> 
</ul>
