Start of Shift Notes:  

Tevatron turnon in progress

what time is it? we don't know - got some "fatal clock errors". talked to some L2 to guys to
see if it was related to what they are doing - they don't know. cleared errors on the advice of bill
badgett. will keep watch as we go into shot setup.

 I borrow the SVT crates to test the data readout with SVDD  
readout since this is needed to read out split real data for 
new GB firmware test. It looks OK. We can directly compare the 
split two data output.  

 We wait for the real data coming.

icicle crashed (2nd time in last hour or so). restarted it.

brief (~3s) cot systems alarm and gas alarm. called cyro, they are working. ignore until
further notice. 


VOLUME FROM SYSTEMS ALARMS IS QUITE LOW. HOW DO WE TURN IT UP?

jj to the rescue! just the standard volume control on a windows pc.

I have finished working on debugging the cable testing  
program using the CCAL_## and LEVEL#_CAL_## crates.  They  
are in their original configuration again. 
Have given them back to DAQ Ace to run tests.

There is something seriously wrong with the ADMEM  
in crate b0ccal05, slot 20: 

(MLE) b0ccal05:Messenger:8:27:59 PM->VISIONread/write failed in slot 20 
MLE) b0ccal05:Messenger:8:28:09 PM->Runtime Error 1, Event 1: Bunch counter mismatch, mismatch
count = 1 

(MLE) b0ccal05:Messenger:8:28:10 PM->Event 2: Bunchcounters in slot 17 (BC=90) and slot 20
(BC=255) disagree (L2B=0)  

L2B 17:  90   3  55   9 
L2B 20: 255 255 255 255 

The VME readout registers simply aren't responding. 
(However, the IDPRom does seem to work.) 

NEed to contact ADMEM experts. 

Larry Nodulman (general cal SPL pager) called back. He suggests
to call people at home:
   - Vivek Tiwari no answer office x2032 and home x4760
   - Mark Mattson no answer office x3596 no listed home number
   - Robin Erbacher no answer office 3442 and home (left message)
Larry also suggested Rick Tesarek, who we reach at home
Mark Mattson (CCAL pager) calles in after about an hour. Bill is
working with Rick on the phone.

Have marked ADMEM in slot 20, crate b0ccal05 as  
offline, so readout of the rest of the crate can continue. 

ADMEM experts should investigate;   is a power-cycle  
warranted in this case? 

Note that to make sure the calibration constants are aligned across the calorimeter, and that ccal05 in particular has new quiet-time constants, Rick requests that a full QIE Calibration be done during the next downtime, with an accompanying CALIB_LOAD supervised by ADMEM experts.

ADMEM problems:
The problem observed with the ADMEM is consistent with the Trigger/Readout FPGA becoming corrupt. We've had 4-5 instances of this type of problem in the last couple of months. No instances of this problem prior to summer 2003. The solution is to reload the FPGA program and recovery seems to be complete. Bill reloaded the entire crate of ADMEMs (not just the offending module). He then took a QIE calibration with just ccal05 and loaded the constants/FRAMS to ensure that everything was ok. The pedestal problems noted below are consistent with beam in the machine.

While this specific problem is fixed, this type of problem seems to be recurrant and does not bode well for the future. Something has corrupted the program in the FPGA. I am suspicious of the software in the crate rather than an external effect (eg, radiation, power, etc).

One more note on the beam-on calibration: 

Did a QIE calibration in crate b0ccal05 under the  
orders of Rick Tesarek.  There were three channels/caps  
with too big RMS, as listed below.   Rick is confident  
that these are due to beam in the Tevatron and should  
not cause problems. 

This can be corrected by taking another QIE Calibration  
during the next quiet-time period.  Please contact ADMEM  
expert (Rick, Mark, or Vivek) when this is possible.

   - final protons are loaded 
   - final antiprotons being loaded 

Plan is to take data with JET_ST3_DECOUPLED[1,433,403] with Silicon 
   - test TEST_MET15_DECOUPLED[1,434,403]
