Operations activitites for March 19-25


<!-- Date: Tue Mar 20 21:47:21 2007 -->
The week started with Store 5290 colliding at 0:01 on Monday with an initial luminosity of 194&micro;b<sup>-1</sup>/s.  However, losses were high and a beam was rescraped.   data taking started with silicon at 0:26.   Most signiifcant problem in the store was an unexplained trip in COT SL8 at about 9:30.   There was a repeat trip at about 2:00am on Tuesday.  The store was terminated at 4:40 on Tuesday after 7.4pb<sup>-1</sup> was delivered of which 6.4pb<sup>-1</sup> (86%) was collected.     
<p> 
While kicking pbars out of the Recycler for store 5292 the 5th transfer was off by 80 RF buckets and the tranfer was lost as a reult the store was 36x32.   Luminosity was low at 129&micro;b<sup>-1</sup>/s whe the store was collinding at 9:28 on Tuesday.   Lost about 30 minutes of datataking to a problem with L2 control node.   There was a problem on the owl shift during the previous store.  maybe they are related.

Store was terminated at 7:21 on Wednesday after 4.8pb<sup>-1</sup> delivered of which  4.0pb<sup>-1</sup> (85%) was collected.

Store 5293 was in on Wednesday at 10:54 with an initial luminosity of 239&micro;b<sup>-1</sup>/s.   There were lots of problems causing significant downtimes during the store including CMX HV trips, a CSL node with memory filling up, and problems with SVX readout.   In addtion, to all the downtimes there was a test of SVT running on all events to measure the timing performance and obtain a sample of Jet events with SVT tracking.    
<p> 
At the end of the store the Tev moved the IP at CDF.   The vertical position was raised by 0.1mm and the vertical angle (dy/dz) was decreased by 100&micro;rad.   The move was successful and will be retained for the next store.   Since we are still off by 1mm vertically and over 200&micro;rad in dy/dz, there will be additional moves in the near future. 
<p> 
The store was terminated at 12:47 on Wednesday after 8.2pb<sup>-1</sup> was delivered of which 6.4pb<sup>-1</sup> (79%) was collected.  Follwoing the store there was a 2hour access opportunity while a wet engine flywheel was swapped at E2.  We went in for a few minor jobs: CMX HV work, miniplug ADMEM, Si Caen module.

During the access on Thursday Dale Stentz looked at the NE CMX HV tripping problem, inspection of CSP geometry and work on a silicon L00 PS which was flakey.    
<p> 
Store 5296 was colliding at 21:11 on Thursday with an initial luminosity of 261&micro;b<sup>-1</sup>/s.   Datataking was very smooth with no significant downtimes.   At the end of the store we took a set of silicon bias scans.   The store was terminated at 23:49 on Friday after 9.0pb<sup>-1</sup> was delivered of which  7.9pb<sup>-1</sup> (88%) was collected.    
<p> 
Store 5297 was colliding at 2:07 on Saturday with an initial luminosity of 237&micro;b<sup>-1</sup>/s.   The beginning of the store was quite rocky with CMX HV trips, PCAL HV problems and silicon DAQ problems.  At 16:30 a power supply for one of the Si VRB crates went into alram for fan failure.  Silicon was removed for the run for 30mins while the supply was swapped.  The store was teminated at 20:26 on Saturday after 6.9pb<sup>-1</sup> was delivered of which  5.7pb<sup>-1</sup> (82%) was collected.    
<p> 
Following the store we went in on a brief controlled access (requested by D0) and furhter isolated the problem NE CMX HV.

Failed to note that Store 5297 was terminated by a quench at E1.

Store 5299 was colliding at 4:22 on Sunday with an initial luminosity of 207&micro;b<sup>-1</sup>/s.  Datataking was very smooth.  After 18 hours the efficiency is 91%.

Store was terminated at 3:46 on Monday after 6.6pb<sup>-1M/sup> was delivered of which we collected 6.0pb<sup>-1</sup> (90.5%).   No significant downtimes.

<B> Summer 2007 Shutdown </B><br> 
On Thursday there was a Proton Plan PMG during which the schedule for the summer shutdown was discussed.   The start of the shutdown is driven by the having new corrector magnets ready for the Booster.   They should be ready to start by August 1.  Other jobs such as power pole replacement are expected to be ready by early July.   Duration of the shutdown will be at least 9 weeks (power poles and magnet replacement).  Installation of new collimator in MI could take significantly longer. 
<p> 
<font color=green> Official start date was set: Monday Aug 6 </font><br> 
Duration to be discussed further at PMG next month
