Start of Shift Notes:  

 
* --- shot setup to start at about 1730 
	- special COT/trigger runs 
	- page cheng-ju, mary and kaori

COT HV for SL1 and SL2 set to zero.  HV for SL3 and 5 lowered 
to 96%.  SL4 still at 100% for XFT Tests. 

Note that the left bar in the HV bar graph display will not come 
up now since two SL are set to zero.  Trigger inhibits for SL1,2 
have been disconnected so it should work correctly.

MCR called.  They are about to inject protons.

Forgot to mention that about 15 minutes ago the CEM CHA WHA 
boxes on global alarms went red then grey.  Nikolai says there's 
a problem w/ slow controls software.  Paged Steve Hahn.  He's 
here working on it.

Steve's first try didn't recover.  He's paged Irina and JC.
Irina here and working w/ him. Haven't yet gotten a hold of JC.

Doug called me in for problems rebooting PISABOX. Nikolay showed me that the program which reads out PMT HVs (C:\pbhvout\pb_hv6.exe) would not start. It would report some error about LSR_ONOFF tags on VNODE1 and VNODE2, and then exit. I called Irina in, and then she found the configuration files (C:\pbhvconf\*) were not there. We found them in pbhvout; maybe Nikolay accidentally dragged the first folder into the second?

However, we still were getting these same errors after putting the configuration folder in the correct place. Irina found that reading out LSR and WHA could be done individually (with "pb_hv6 read wha", for example), but CEM and CHA failed. After resetting the SY127 CAMAC controller front panels, these worked also. Finally, the normal readout ("pb_hv6 auto_read") started up normally.

Still not clear why the complaint is about LSR_ONOFF tags on VNODE1 and VNODE2. I checked the iFIX databases on PISABOX, VNODE1, and VNODE2, and this tag appears on none of them. A clearer error message would have made this go much faster. Will ask J.C. Yun when I get a chance.

MCR calls.  They had trouble w/ a sequencer, which delayed things 
a bit.  Resolved, so starting shot setup.  Expect to begin 
loading of final protons in about an hour.

Prompted by the unexpected erasure of the ADMEM in one of the CCAL_00 crate and heap corruptions errors in b0pcal02, we put a memory usage monitor on crate b0pcal02 for a five day period. No evidence for a memory leak, per se, but there is some strange behaviour when the memory usage drops suddently at the beginning of a SMXQIE calibration (and to a lesser degree, the QIE ADMEM calibration). See the Plug e-log here for more details

MCR message tells us that they're starting to load "final" 
protons for store #3231

paged rob, kaori, mary and cheng-ju.  all are on their way in.

pbars loaded and TeV at Flattop.

Scraping complete. 

	- protons = 8710E9 
	- pbars   = 1000E9 

	- Lumi = 50.0E30 

waiting for HV ramps to complete.

Track trigger rates look okay even with the entire XFT SL2
masked on!!!

COT LS2 top-lest graph is empty.

Actually the top left graph is not empty (~27000 entries per
bin) .  That plot diplays the XFT segment occupancy as a function
of phi for SL2.  Since we masked on all the SL2 wires in the XFT
(over 2000 wires), the segment occupancy for SL2 is uniform and
very high. 

Marked Bad, explanation:
L1T Tests for XFT w/ COT HV OFF on SL1,2. No silicon in run.

Marked Bad, explanation:
L1T tests for xft w/ COT S1,2 OFF and S4 at reduced voltage.
No silicon in run either.

  * while waiting for shot setup to begin: 

        - Nikolay found problem w/ slow control software for Pisa 	 
          Boxes, Steve Hahn and Irina called-in to fix it 

        - MCR gave us some quiet time, so did full set of calibs 

        - myriad set of pulsar test runs 

  * store 3231 loads final protons at ~22:00 

        - initial lumi = 50E30 

        - begin w/ COT/xft test runs 
                179096 - SL1,2 OFF, SL4 at 100% HV 
                179097 - SL1,2 OFF, SL4 at  98% HV (70% gain) 
                179099 - SL1,2 OFF, SL4 at  96% HV (50% gain) 

          csl notified to flush 179096, when they call back, tell 
          them about the others.
