<p>Summary for 26-28 December 2005 
<ul> 
<li>26 December 2005: Store 4564 is terminated normally at 0605 hrs. 
    We recorded 2.3 pb-1 at 93% efficiency. Store 4567 starts at 1406 hrs, 
    with an initial luminosity of 141e30. We start running quickly, but 
    about 2.5 hrs into the store, we were down for about 0.7 hrs due to 
    a <a href= 
'/cgi/elog/elog.pl?nb=2005&action=view&page=1080&frame=2&anchor=16:33:28.939'> 
    run control/partition</a> problem. Other than that, relatively smooth 
    running.</li> 
<li>27 December 2005: Store 4567 is terminated normally at 1201 hrs. We 
    record 3.8 pb-1 at 85% efficiency. Store 4569 starts at 1638 hrs, with 
    an initial luminosity of 168e30. We are now back into the 
    pre-shutdown high luminosity territory. However, we get a silicon 
    integrated dose alarm during the squeeze (from svrad0 and 1) and in 
    addition, the silicon CAEN 1 shut itself off. We start running 
    smoothly with the high luminosity trigger table. When we switch to 
    the default trigger table, we got a series of small problems:  
    silicon L00/ISL crate 7 trip, b0tsi00/02 hangs, and an RTserver 
    problem linked to b0dasvx02. Overall, not too bad.</li> 
<li>28 December 2005: Store 4569 ends at 1523 hrs with a TeV quench at F4. 
    No problems for the CDF silicon due to this quench. We recorded 
    4.4 pb-1 at 90% efficiency.   
    Store 4571 starts at 2129 hrs, with an initial luminosity of 168e30. 
    However, the silicon radiation system issues two integrated dose alarms 
    within a span of 3 minutes. Both CDF and D0 see high pbar losses. 
    The Accelerator TeV group is <a href= 
"http://www-bd.fnal.gov/cgi-mach/machlog.pl?nb=tev05&action=view&page=459&anchor=100414">aware of this</a> 
    and are working to improve the tunes during the squeeze. There is about 
    15 min of down time at the start of this store -- it seems to be a    
    wait for losses to subside. After that, the startup was quick and the 
    running smooth.</li> 
</ul>

<p>Store 4571 continues, and the running is relatively smooth. 
   The current efficiency is 88%. We continue to try out <a href= 
'/cgi/elog/elog.pl?nb=2005&action=view&page=1088&frame=2&anchor=13:13:03.012'> 
   remote CO shifts</a> 
   from WH11. Store 4571 will be kept until the mid- to late 
   owl shift.

<p>Store 4571 is terminated normally at 0308 hrs. We recorded 4.5 pb-1 at 
   90% efficiency. Store 4573 starts at 0627 hrs with an initial luminosity 
   of 139e30. There is no silicon integrated dose alarm during the squeeze. 
   We start off reasonably well, but about 15 minutes into the store, we 
   went down for about 20 minutes due to a silicon L00/ISL HV trip that 
   also required Hockerization of CAEN crate 7. Running after that is 
   fairly smooth, but there are a bunch of little problems. 
   Store 4573 should be in until the 31Dec05 day shift.

<p>New Year Weekend Summary: 31 December 2005 - 02 January 2006 
<ul> 
<li>31 December 2005: Store 4573 is terminated normally at 1712 hrs. 
    We recorded 4.8 pb-1 at 84% efficiency. The significant down times 
    are: PEM 05W ADMEM (pcal01/slot18) configuration FRAM corruption - 
    40 minutes, and EVB proxy problem - 20 minutes. We also did a series 
    of trigger table tests from 0800-1050 hrs. Store 4574 starts at 
    1939 hrs with an initial luminosity of 156e30. We start running without 
    problems, but at about an hour into the store, we went down for 
    15 minutes due to a silicon L00/ISL trip (CAEN crate 7 again).</li> 
<li>01 January 2006: Store 4574 continues, and running is very smooth 
    during the first 12 hours of this new year. Then, we get a series of 
    down times starting from 1206 hrs which totaled to about 2.2 hrs. 
    There were beam loss problems: 
    TeV abort gap losses, AGIGI2, and a TeV RF6 trip. We also had a series 
    of SVX problems when bringing back the silicon after the TeV abort 
    gap losses, and an EVB problem in b0evme23.</li> 
<li>02 January 2006: Store 4574 is terminated normally at 0306 hrs. 
    We recorded 5.0 pb-1 at 86% efficiency. Store 4575 goes in at 1950 hrs 
    with an initial luminosity of 175e30. The TeV is now back to its 
    pre-Dec05 shutdown initial luminosities. We did not start up quickly - 
    the CLC HV glitched at the start. Then there was a series of 10 min 
    or so problems that reduced the data taking efficiency: L3, plug HV, 
    and AGIGI2.</li> 
</ul>
