Detector Operations for Week of January 29 to February 4


<!-- Date: Mon Jan 29 23:08:35 2007 -->
The week starts with store 5199 spinning and pbar stacking and stashing.   Preparing for access to MI to replace NUMI dipole HV101.   Plan is put shot in on Tuesday owl shift and spin through much of the MI access.   With a stash of almost 400E10 in the recycler this store could start out with luminosity in near record territory.  We are finishing out store 5199 with a new trigger table (PHYSICS_4_01 [3,856,667]) which has additional triggers on luminosity enables for L~250-275E30.

Store 5199 was terminated normally at 1:00 on 1/30 after 7.0pb<sup>-1</sup> had been delivered of which 6.2pb<sup>-1</sup>(90%) were recorded.

Store 5201 was colliding at just after 7:00 on 1/30 with a record initial luminosity of 275E30.   We lost the first 25 minutes of the store to an ISL HV trip that required expert help to recover.   We ran relatively smoothly for the remainder of the store.   There was a TevRF trip during the store with little loss of luminosity.   However, the store was lost at 11:26 on 1/31 when another RF station tripped.  A total of 8.9pb<sup>-1</sup> were delivered of which 7.3pb<sup>-1</sup>(82%) were collected. 
<p> 
After store 5201 was colliding the MI went into access to replace a NUMI dipole which has developed a water leak.  Estimated downtime for the replacemet is 72 hours during which there will be no stacking.   At the end of the store the Tevatron went into access to reconfigure sextapoles.  Unfortunately an Ion pump at A18 was damaged during this work and the Tev A1-3 needs to warm up to 100K to replace the Ion pump connection.  This will hold off beam from the Tev until at least Friday evening.    
<p> 
CDF will go in on access Thursday to complete BMU work started last week and replace fan packs on the upper NE and upper NW COT racks.

Report from 9am meeting:  MI turn-on has gone smoothly and stacking resumed Thursday evening.  Pbar is on a short access this morning and will concentrate on getting stacking and transfer efficiency back.  Recycler has a few problems with Pelletron but should be ready for a shot. 
<p> 
Tevatron vacuum is improving.  A3 is cooling.  A1 vaccum has been slow to recover but is now improving.  Vacuum is expected to be good enough for A1-A2 cooldown starting this afternoon.   The A17 Separators were turned on ovenight and operated without significant problems so bakeout is not needed. 
<p> 
If progress continues as in the last day the schedule has 12 hour Tevatron cooldown into Owl shift Saturday, access to remove equipement followed by Tev turn-on during day shift Saturday.   Shot setup would come evening shift Saturday. 
<p> 
From run coordinator: "The ground hog saw good beam [in MI] which means 6 more weeks of good running" 
<p> 
We will complete elevation survey this afternoon, close the IMUs and search and secure on evening shift.

This long week is coming to a close with the picture looking up on all fronts.  Tevatron is cooling with prospect for shot setup on Saturday afternoon.   At CDF we did a number of jobs during this extended accelerator downtime.   
<ul> 
<li> Plug source calibration runs 
<li> <ul> Many access jobs: 
   <li> BMU HV problems on east side which had accumulated over the past few weeks 
<li> Two flakey Plug CAEN HV modules were swapped 
<li> Swapped bad fan packs on Upper NE and NW COT racks 
<li> Reseated HADASD cable behind south wall (b0ccal11) 
<li> Fixed bad WHA channel on 21E (SHV connector)  
<li> Repaired bad memory on FRED L1 Decision board 
<li> Swapped ISL FIB in attempt to fix some bit errors 
</ul> 
<li> Elevation Survey of the Detector 
</ul>

The week ended with store finally going in at 1:15 on Sunday with an initial luminosity of 145E30.   For the second time in a month the CMU calibration pulser was on during the store.  It took several hours to recognize that there was a problem and almost 12 hours to decide that the the problem was the pulser.  After rebooting all of the ccal crates the pulser was off.   However the store lasted only a few minutes after the rcovery before it was lost due to a spurious vacuum abort at C3.   A total of 3.6pb<sup>-1</sup> was delivered of which 3.1pb<sup>-1</sup>(85%).  There was a short test of PHYSICS_TEST_4_01 [8,859,671] at the end of the store. 
<p> 
The cause of the calibration CMU pulser being on is somewhat mysterious.  During the downtime on Friday a new FER code version was tested which was supposed to ensure that the pulser would never be on during beam data.   The tests were deamed successful and the pulser appeared to be off.  As Bill B said, the FER code may be necessary but not sufficient for turning off the pulser.  Further investigation of how the pulser system works is needed.
