Store ended at 11:00am.  CDF had an efficiency of 73% for the store.  We had two separate level 2 problems.  These are NOT pulsar problems but rather hardware problems that feed the L2 decision crate.  The first was a problem with the ISLCLK/ISOLIST board.  (we still have not fully isolated the problem).  The second was a bad SMXR card in CCAL02.  We had to request an access to swap it (which we did).  Minor silicon work was also done on the access. 
 
We are now doing calibrations and detector checkout before the next store.  The current stack is about 180ma. 
 
There may be some 150 GeV octopole work prior to shot setup.

Monday Night 
 
Well, shot setup had an adventure.  Took a while to recover from access,then they had problems with t:clock and I believe spent some time looking at the octopoles at 150.  Finally shot went in around 9:30pm -- initial lum at CDF of 96e30.  CDF had a smooth startup and are already 70% efficient after the first hour of the store.  EXCELLENT! 
 
We had silicon cooling troubles this afternoon -- 3 separate and unrelated failures gave us headaches.  Luckily they all occurred during no beam and thus we suffered no down time as a result.  Silicon guys did a nice job checking things out prior to the shot.

Store went in late yest evening with an initial lum of 95e30.  CDF is on top of its game.  We are some 15hours into the store and we are on the first run and we are &gt;90% efficient.  No problems worth reporting at the moment. 
 
GREAT job by everyone on the last few accesses to make the repairs and to NOT create new problems.</pre>

<pre>Wednesday Status 
 
Continues to be a model store.  Ran smoothly with two runs for the entire store.  We are at 92% efficiency with all systems participating and operating well. 
 
Store to be dropped shortly.  Shot setup to immediately follow.  Total pbars available is 200ma. 
 
Pulsar guys were able to reduce the done timeouts by "wiggling" a fibre optic cable...</pre>

<pre>here is a bit more details: the optical cable (which was wiggled) was between IsoClique and IsoPick boards in the L2CAL system, not in the Pulsar crate(L2CAL feeds data into Pulsar L2 decision crate)... that has reduced the L2 decision timeouts from ~8 per hour to a few per store (what's left has been identified as due to SVT timeouts).</pre>

<pre>Friday 
 
WE have had a tough day.  Thursday -- we were running well until we shot ourselves in the foot.  We were doing maintenance on the ISL chiller system -- fallout from problems the day before when we made a mistake abd brought the entire system to atmosphere.  Once that happened, we could not power 1/3 of the silicon port cards. 
 
Today we made a 6 hour access and fixed the problem.  I won't go into the details 
 
now struggling with a solenoid problem</pre>

<pre>Friday -- the real fridya 
 
MAnaged to get solenoid powered.  We have 4 redundant quench protection circuits.  One side of one circuit was noisy and caused us to pull the abort.  The problem is in the cabling and is NOT in the solenoid because we don't see this noise everywhere.  For the time being, I just took this protection out and we have 3 redundant systems.  Will trouble shoot it later. 
 
Shot had an initial lum of 72e30. 
 
We had a few startup problems but not bad --- All systems back and running well.  Team silicon rejoined team luminosity.  Welcome back! 
 
Store will end this evening.  Problem with C2 wet engine so store may end even sooner....  We will see.</pre>

I will be in texas Saturday-Thursday turkey hunting.  I can be reached in early AM and late PM on cell phone if there is a problem.  399-2609.   Mike Lindgren will be available to Willis if he needs a hand.  Hopefully it will be smooth sailing.</pre>

Weekend Summary: 
<ul> 
<li> 
CDF ran fairly well over the weekend, with no major problems 
and an average efficiency of about 91% 
</li> 
<li> 
Store 4108, with an efficiency of 79%, ended about 0400 hrs on 
Saturday. 
</li> 
<li> 
Store 4109 started right away, had an initial luminoity of 93e30, 
and ended with an average efficiency of 93%. Run 196902 (2.5pb-1) 
had a problem at the end: TL2D bank corruption. D0 took a 2 hour 
controlled access at the end of the store, we stayed out. Problem: 
the SMX-QIE calibrations failed, but with no follow-up action. 
</li> 
<li> 
 
Store 4111 started about 1500 hrs on Sunday. Three pbar transfers 
were lost, leading to a 36x24 store with an initial luminosity of 
60e30. About 1.5 hours of data at the start are bad: a big chunk 
of the west central SMX/XCES had bad calibrations. The SMX-QIE 
calibrations taken after store 4109 termination were bad and seem 
to be related to new SunOS compiled calorimetry front end code. 
The new code was backed out, and the retaken SMX-QIE calibrations 
are OK. Other than this, good efficiency so far: about 90%. 
</li> 
</ul>
