<pre>Week of 06 March 2006</pre>


<!-- Date: Mon Mar 6 17:03:07 2006 -->
<p>The schedule of the work for this week is <a href=                 
  "http://ncdf67.fnal.gov/~tesarek/shutdown06">bere.</a> 
   We are on schedule. However, the elevation survey of the 
   CDF detector has started late today, and should be completed 
   by tomorrow. This means unrestricted detector access.

<p>The 400 hz motor generator maintenance on MG-1 and MG-2 
   have been completed today. The methology of the elevation 
   survey of the CDF detector has been changed, and so the 
   survey will be finished off next week. The surveyors will 
   bring in the survey tie-point from known points inside the 
   TeV tunnel, both east and west, and then shoot the elevation 
   of the CDF detector.

<p>All 400 hz motor generator work has been completed, so all 
   detector power is back. Work within the central arch regions 
   will soon be allowed, as we now have the JHA that covers the 
   protection of the fragile optical fiber systems in the 
   arches. For all those who wonder why the AD takes electrical 
   feeder maintenance work seriously, look <a href=

<p>The CMX HV work is 75% done, and flammable gas is expected to 
   be off by next week. CMP bottom preamp replacment work is 
   ongoing, and appears to be successful. In addition, the DAQ 
   group has got L2 torture and cosmic ray running going with the 
   software event builder -- this is good news. The CLC, CP2, and 
   plug CAEN SY527 mainframe maintenance is now proceeding at 
   full speed.

<p>The CMX HV work requiring flammable gas is done. Well, sort 
   of -- about 15 minutes of checks is desired on Monday. 
   At that point, we turn off Ar-Ethane. 
   Our low beta quad Kautzky valves were all serviced by the 
   TeV Cryo group. Recall that it was a failed Kautzky valve 
   from the last TeV quench that generated a pressure wave that 
   destroyed the F47-2 dipole. The detector elevation 
   survey will be done on Monday and Tuesday. The big ticket item 
   for us is the start of the NW toroid Hillman roller work.

<p>Friday 9AM Accelerator Shutdown Meeting Summary.  
<ul> 
<li>The D0 L00 silicon project is on schedule.</li> 
<li>About 450 lbs of zebra mussel shells came out of the inital 
    ICW water pipe flush.</li> 
<li>The TeV magnet roll survey has been completed: There are 38 
    magnets whose roll changed by over 1 mrad -- these have now  
    been scheduled for realignment. The F47-2 magnet replacement 
    work found additional collateral damage from the failed 
    Kautzky valve: the TEL-1 device has a large He leak: <a href=

    bad news!</a> 
    The work on installing a new collimator for us 
    at A48 is progressing well: The holes in floor have been 
    filled, and so the new collimator configuration can now be 
    installed.</li> 
<li>The Booster RF guys are really upset: A 15 minute 
    cooling water pressure surge blew out many water hoses 
    in a large fraction of the Booster RF stations. This will  
    cost a lot of time to fix. Evidently, these Booster RF  
    stations have a lots of "old" water hoses that failed.</li> 
</ul>
