January 2006

January 3, 2006 (J. Dobbins, C. Strohman, M. Palmer, E. Tanke): New FLMA with accumulator board installed in CESR

  • The new FLMA with accumulator board has been installed in CESR.
  • Note that the problem with the channel mapping (see 31-Dec-2005) has been fixed.

February 2006

February 14, 2006 (C. Strohman): FLMA now has ethernet card

  • A ColdFire ethernet module was installed in the FLMA box: CBI_CF02, address 192.168.1.146
  • Added a dual Xbus/RS232 cable (the RS232 side is currently not connected)

February 21, 2006 (C. Strohman): Two more accumulator boards installed in the FLMA module

Accumulator boards were installed on the two horizontal ADC boards (Analog Card #1 and #2). Please refer to the programming manual for the addresses used to access these additional cards. Each card has a pair of jumpers that set the BOARD_ID. The jumpers are set to correspond to the analog card numbers. If a board needs to be replaced, be sure to install one that has the jumpers set properly. There are 3 spare boards in Charlie's office; one for each of the 3 BOARD_IDs. The boards are clearly labeled.

Unlike the original accumulator board on the vertical channel, these two new accumulator boards are only intended for "Geo Global Rate Data" and "Geo Channel Rate Data". Don't try to use the lookup table for "Bunch Rate Data", "Fast Global Rate Data", nor "Slow Global Rate Data". The lookup table will not use "ADC 0" nor "ADC 7". A major restructuring of the Xilinx code is required before the lookup table can be used.

The front panel 8-pin miniDIN connector used to program the Xilinx chip on the accumulator boards is NOT connected internally. If a Xilinx code change is required, the box must be opened and the cable must be connected to the appropriate accumulator board. It might be possible to daisy-chain the configuration EEPROMs, but that will be left for a future project.

  • The measured power used by the FLMA module (3 ADC boards and 3 accumulator boards) when it is not doing anything useful:
    • 0.90 amps @ 2 volts (1.8 watts)
    • 7.5 amps @ 4 volts (30 watts)
    • 0.8 amps @ 5.5 volts (4.4 watts)
    • 0.32 amps @ 12 volts (3.8 watts)
    • 0.70 amps @ -5 volts (3.5 watts)
    • Total = 43.5 watts

  • The ColdFire ethernet module that was previously installed in the FLMA box has been taken out and re-installed in the BSM23E box

March 16, 2006 (E. Tanke, M. Palmer): FLM Calibration Checks

  • MS Plan
    1. Run MCA digital analysis to verify channel-by-channel gains/HV settings
    2. Analog readout pedestal calibration
    3. Take a full load of e+ to HEP conditions to check gas bremsstrahlung background
    4. Optimizer checkout using FLM accumulator signals
    5. Install new database node(s) for raw FLM accumulator data if time permits (otherwise Tuesday)
  • MCA data taken with FLM_V1 (24 channels), Tglob=1400, bunch selection file=mca_bunches.dat, 250 bins, data stored in subdirectories of tanke/cesr/ts101/flm03w/test_24c_mca/2006_03_16 :
    • /0804 500 loops, MCAMIN=-20000, MCAMAX=1000 (data taking took ~22 minutes)
    • /0835 100 loops, MCAMIN=-41000, MCAMAX=1000

March 29, 2006 (E. Tanke): Units for the FLM ACC nodes

  • The data in the FLM ACCx CHy nodes correspond to individual bunch rates (in Hz) for individual channels, whereby:
    • x=0 => vertical accumulator board
    • x=1 => first horizontal accumulator board
    • x=2 => second horizontal accumulator board
    • y=0..7 => channel number (NOT geometric)
    • The size of these nodes is 183
    • The bunch rates are in order of accumulator board bunch number
  • The units in the FLM ACC HORZ and FLM ACC VERT nodes are now Hz and Hz/mA. Note that "fff getall" will give format errors for numbers equal to or larger than 1000000.
  • FLM ACC HORZ 1-16 reflect the channel by channel rates, in Hz. They are NOT in geometrical order

June 2006

June 15, 2006 (E.Tanke): FLM Installed at 3W in view of the upcoming CLEO run

  • The FLM has been installed at 3W in view of the upcoming CLEO run; see the CESR Elog page

July 2006

July 05, 2006 (E.Tanke): FLM Up and running

  • Following the 15-Jun-2006 installation, the FLM was taken out again because CESR had to be run at high energy to rinse the machine following a vacuum intervention. Today the FLM was re-installed and tested.
  • A timing scan was made on the vertical channels; the optimal timing was found to be around 1400. The FLM now operates with this timing.

July 12, 2006 (M.Palmer, E.Tanke): FLM MCA data taken

  • MCA data taken with FLM_V1 (24 channels), Tglob=1400, bunch selection 9x3, 250 bins, data stored in tanke/cesr/ts101/flm03w/test_24c_mca/2006_07_12/0810 :
    • 500 loops, MCAMIN=-20000, MCAMAX=1000
  • Subsequently also new analog pedestals were taken.

July 19, 2006 (E. Tanke): Units for the FLM BUN VERT node

September 17, 2006 (M.Palmer): FLM Calibration

Installed a new set of FLM high voltage values (version 7) based on last week's calibration data (taken 9/11). As expected, this has resulted in a shift in the analog output values but only slight adjustments to the digital (threshold-based) readout. For this calibration, the operating voltages for all channels had to be raised to maintain the target pulseheight for minimum ionizing particles. This suggests that we are now seeing the effects of radiation damage to the detector.
