<p>Store 4745 ended for us about 0600 hrs, 10Jun06, and we 
   recorded 0.038 pb-1 at 86% efficiency. This store provided 
   good exercise in getting back to data taking mode. We also took 
   calibrations and cosmics. 
</p> 
<p>The AD plan is to get a standard HEP 36x36 store in this 
   evening: Take as much of the stack in the Accumulator (82e10 
   at 1715 hrs) and put it into the Recycler, cool it, and then 
   shoot them into a collider store. We will probably need 
   several 50e30 or so "usual" luminosity stores to fully 
   shake down the CDF detector and get back into standard 
   data taking mode. It is important to get stable beam  
   experience and get the silicon in to provide beam line 
   measurement feedback for the TeV group. We have several low 
   priority access requests, but it is better to hold off and 
   get in a few stores before going in. D0 has indicated they 
   will want another 2 shift access to address the noise 
   their A-layer muon chamber readout induces into their  
   calorimeter (which involves opening their detector and 
   firmware reprogramming). However, they also want to get a 
   few stores in before doing so.

<p>Store 4759 starts at 2347 hrs, 12Jun06, with an initial luminosity of 
   29e30. This may not have the identical luminosity calibration as before the    Mar06 shutdown as the  CLC PMTs were replaced during the shutdown. The 
   D0 initial luminosity is 21e30. The silicon was not in. 
   There were problems at the start of the store due to COT SL3 HV trips 
   and L3 farm problems. We also did XFT upgrade runs for the middle part    of the store with readout lists disabled. We ended data taking about    1351 hrs. We recorded 1.0 pb-1 at 60% efficiency. We continue in our 
   startup -- find and fix problems as they arise, and re-learn how to 
   run CDF in data-taking mode. Tevatron studies 
   doing separator scans started at 1400 hrs and ended at 1703 hrs. It 
   did not appear that our A48 collimator alignment was done. This store 
   was quite stable, and the abort clean. 
</p> 
<p>Setup for the next shot began at 1815 hrs. It will most likely be a 
   40e30 store. The silicon group watched over store 4759, and believe 
   conditions are safe to include the CDF silicon. They will include the 
   silicon for 3-4 hours in the next store -- 3 hrs or so after the start 
   if before 2300 hrs, or early in the morning of 14Jun06. The SVT group 
   has preloaded patterns based on the COT based beamline, and should 
   get a

<p>Store 4760 started at 2021 hrs, with a low luminosity 
   of 20e30 because the D17V separator was at the wrong 
   polarity. After reversing and rescraping, the luminosity
   is 54e30.

<p>Store 4760 had a shaky start, we ran rather smoothly over the 
   owl shift and into the morning shift: A single run (but without 
   the silicon) until 0900 hrs, with an efficiency of 94%. We 
   had some problems in the morning with L2 decision timeouts. 
   The TeV abort gap current, AGIGI2, increased steadily from 
   the start of the store to a problem level of 14e9. It     
   was due to the TEL1 electron beam being too far away from the 
   p/pbar beams being too far <a href= 
'http://www-bd.fnal.gov/cgi-mach/machlog.pl?nb=tev06&action=view&page=98&anchor=10:51:42'> 
   away.</a> When it was fixed, AGIGI2, went down to acceptable 
   levels. The silicon was included in running at  1318 hrs. 
   We ran with the silicon for about 15 minutes or so before 
   TeV beam was aborted. It was a clean abort due to some 
   <a href= 
'http://www-bd.fnal.gov/cgi-mach/machlog.pl?nb=runco&action=view&page=641&anchor=14:51:51'> 
   unintentional interference.</a> We got about a two hour 
   access from 1447. We replaced TOF ADMEM in b0wcal07 slot 9 
   and this fixed the problem, and checked wedge 21 of CMX for 
   damage but found none. Other work done during this access 
   period:  b0htdc00 slot 5 TDC, which has been causing 
   readout problems, was replaced;  the hot west PHA trigger 
   tower problem was diagmosed (corrupt ET lookup table in 
   ADMEM) and fixed by recalibration and downloading.

<p>Pro-Store 4767 was being accelerated about 2020 hrs when
   there was a quench at B2. The silicon was on standby, and 
   there were no problems on our end.

<p>The L3 farms group got the Scientific Linux version of the L3 filter 
   to work with run control, and we should now be able to test it in a 
   store. Store 4772 starts at 1307 hrs, with an initial luminosity of 
   67e30. The CLC calibration is now closer to its final value, but one 
   more iteration is needed. Data taking started without silicon, but 
   the silicon joined in about 45 minutes later. We are running quite well: 
   At 1946 hrs, we have recorded 1.0 pb-1 at 86% efficiency.

<p>Store 4772 datataking ends at 1500 hrs, at which time TeV 
   studies commence. We recorded 2.2 pb-1 at 78% efficiency. 
   We ran fairly well, and silicon was included when the DC beam 
   in the abort gap was small. From 2124 hrs, 15Jun06 to 
   1047 hrs, 
   16Jun06, the silicon was excluded when TEL1 did not keep 
   AGIGI2 within the silicon "safe" level. The silicon AGIGI2 
   alarm level is now at the MCR "problem" level of 7e9. TeV 
   experts had to work on it to bring it down. 
   Several other 
   tests were done during this store. The SL L3 filter was 
   tested and it ran for several hours without problems. 
   Offline validation against runs taken with the RH L3 
   filter need 
   to be done before we switch over for good. 
   TOH HV scan runs with min-bias triggers were also taken.

<p>Weekend Summary: 17-18 June 2006 
<ul> 
<li>Saturday, 17Jun06: Store 4774 starts at 2119 hrs, 16Jun06, with an 
    initial luminosity of 104e30. Unfortunately, it ends at 0122 hrs with 
    a TeV abort due a ramp dump at A2 -- no quench and no problems with 
    the silicon. We recorded 0.3 pb-1 at 28% efficiency. There were lots 
    of problems with L2/SVT: b0svt05 had an AMSRW board problem, which 
    was fixed when it was <a href= 
'/cgi/elog/elog.pl?nb=2006&action=view&page=408&frame=2&anchor=05:59:31.242'> 
    replaced.</a> We took calibrations and cosmic rays until TeV studies 
    began and which lasted most of Saturday. Store 4778 begins at 1735 hrs, 
    with an initial luminosity of 58e30. We start a bit slowly, but not 
    that bad. We had significant deadtime from L2/SVT - b0svt06 which was 
    related to the <a href= 
'/cgi/elog/elog.pl?nb=2006&action=view&page=410&frame=2&anchor=23:34:31.450'> 
    poking around</a> 
    done to b0svt05 and it was fixed about 4 hours into the store.</li> 
<li>Sunday, 18Jun06: Store 4778 continues. At about 0155 hrs, we were down 
    about an hour for silicon ladder trip and CAEN crate Hockerization. 
    We ran fairly smoothly after that for about 5 hours until about 0820 hrs 
    when we had a bunch of little problems: CMX trip, COT TDC DTOs and 
    silicon resonances, which appear to be <a href= 
'/cgi/elog/det-system-elog.pl?nb=silicon&action=view&page=306&frame=2&anchor=15:10:41'> 
    more frequent now.</a> Store 4778 was terminated normally at 1609 hrs. 
    We recorded 1.6 pb-1 at 77% efficiency.</li> 
</ul>
