Start of Shift Notes:  

 
Run in progress.  Plan is to continue taking data.

Subfarm 9 is fixed now and may be included in the next run  
after Level3 cleanup 

The problem was in converter 09 

MCR calls back.  they're done playing w/ collimators.  AG losses 
actually a bit worse (13k before they played, now 14k).  They 
wanted to try to reduce these losses a bit before shift change 
(at 20:00) so that they could avoid having to call-in experts. 
We'll keep an eye on it.  It was quite flat for the first 3 hours 
of our shift, they expect it to stay this flat. 

Also, next shot will likely take place when avg lumi=10E30 and 
stack big enough.  MCR guessed around 00:00, but said they'd have 
the next crew chief call once they'd decided on a shift plan

Dr. Pitts calls with a trigger table plan for the start of the 
next store: 

	- start w/ the HIGHLUM table on the whiteboard, 
	  DPS disabled 

	- once lumi < 40 E30, switch to regular table 
	  DPS enabled 

He suggests we take a short run w/ the HIGHLUM table towards the 
end of this store since this table hasn't been used since Jan  
(he's worried that perhaps a tagset has changed). 

AG losses have fallen back to their previous ~13 kHz.

Phoned MCR.  They say they'll keep store until lumi is 10E30, 
which they guess will occur sometime between 0400-0600.  Stack  
is presently 154 mA. 

talked to Mary C (ops manager tonight) and she agreed that  
kevin's plan sounded like a good one. 

we'll pause now to perform this test w/ HIGHLUM table.  that way 
kevin can check the rates before going to sleep.  if it goes well 
then the owl shift can "relax" and ride-out the rest of the 
store.

now the fun begins... 

natasha tries to bring-in L3 subfarm 9 as per arkady's request. 
it doesn't work.  things get worse as aces try to recover. 
L3 paged.  Jeff M here working.

Had the following messages in the error display, when starting the run:

Event Display pictures - yellow circle consists of xft hits.
Picture #1 - stadard COT view with yellow circle
Picture #2 - close-up view of the arc with "SetDisplayCells" on,
one can see number of xft hits.

What I know about coloring scheme for XFT hits is:

 green  : prompt hit
 blue   : delayed hit
 yellow : both

the xft SL2 is masked "on" in order to account for the reduced
COT voltge on the inner SL (in the case of SL2, reduced==off)

From the MCR elog: 


The Plan:   
Terminate store when the stack reaches 190E10 or the average   
luminosity reaches 10E30 (whichever comes first). After store,   
stack to 50E10 and transfer to Recycler. Shot strategy, Protons   
265-275E9 per bunch, pbars per guidelines.

 Level3 failed Partition several times complaining about 
transition failure on the processor node b0l3157. It  
turned out that the node ran out of disk space because of 
enourmous number of core.xxxxx files. I cleaned up  
the disk, now the node is ok, so is level3. I will 
suggest Guillelmo to check why cores accumulate.There is 
no immediate danger for other all nodes, as far as I can see, 
there is plenty of disk space. 

Irina comes-in to update version of pb_hv6 that's monitoring 
pisaboxes.  When she/steve fixed yesterday's problems they  
apparantly downloaded an old version.

AG losses have poked-up just above 15k a couple times.  both 
times they went back below w/i about a minute.  Should keep an 
eye on it.

  * run ;  TeV is planning to squeeze store 3231 for a 
    good while longer. 

        - at ~20:00, ramp silicon+wire chambers to stby for MCR 
          to play w/ collimators 

        - at ~22:00 took a short run (179105) w/ HIGHLUM table 

                > K Pitts said rates looked ok 
                > also got L3 subfarm 9 back 

        - at ~23:00 went back to dflt table 

  * plan: 
        - continue taking data w/ dflt table until end of store 
                > watch abort gap losses 

                > if collimator gynastics required, don't forget 
                  to reduce voltages as per whiteboard 

        - between stores: 
                > checkout, calibrations, L2 torture 

        - run plan for new store: 

                > begin w/ HIGHLUM table, DPS disabled 

                > once lumi < 4E31, switch to dflt table, DPS 		 
                  enabled
