After calibration you will return CFT crates to global run and check histograms from ft_examine. Do also ‘Checklist Between Stores’ to save histograms. Read hit map analysis in the Checklist. You should have zero of hot and cold modules and tripts. Also re-start cft_gui at Tracking station

Set parameters and download Take data Transfer calibration results from calibration tables to electronic tables SDAQ run (with ITC option asserted) will put calibration constants into calibration tables cft_gui uses electronic tables, therefore one needs to transfer calibration constants from calibration tables to electronic tables Check the quality of calibration run Calibrate time, not needed for crate 0x53 Align pedestals-this only after you installed new board Calibrate analogue thresholds write peds_zero Thrs to afpga Set run parameters and download Take data Transfer calibration results from calibration tables to electronic tables Check the quality of calibration run thrsToAfpga Download for global bias running Before re-turning crates to global run download all crates (click on download in cft_gui for each crate) Calibration of analog thresholds has to be last step because analog thresholds may depend discriminator thresholds. After installation of new board you have to calibrate discriminator thresholds (except of crate 0x53) and analogue thresholds. Do time calibration and align pedestal as soon as you can. Alignment of pedestals has to be followed by calibration of analogue thresholds.

4. 21 November, 08, jadzia warchol, ext. 8341, phone 357-4232 4 Calibration in Brief When to make calibration You need to make new calibration when: New board was installed Hit maps show “hot” regions and/or depleted regions It usually takes three hrs to make full CFT calibration. Calibration depends on the temperature of AFE boards therefore it should be done when temperature is stable (archiver enables you to check that). Discriminator calibration needs to be done when there is no beam in the accelerator. Time calibration can be done with beam in the accelerator. Calibration of analog thresholds can be done with the beam in the accelerator, however you need to check that beam is not detected by CFT. To check if beam is detected by CFT look at pulse height distributions in layers closest to the beam: for example boards 5A6&A7, 3A2&3. I did often calibrate analog thresholds during proton injection tune-up.

If you swapped board you need to do it, but it does not have to be done before the first store with new board. The values to which pedestals will be aligned in calibration run are hard coded in smt_device_2afe.py in the following lines: AFE2PED=8 (for cps) AFE2PEDFT=45 AFE2PEDFPS=10 (for fps) The procedure for alignment of pedestals is following: 1.Decrease bias by 0.4 V a) Set bias_offset to –0.4 ( reachable via global parameter->SVX Parameter) b) From VRBCR menu: update bias c) From VRBCR menu: On bias 2. From VRBCR menu: zero peds_thrs in afpgas 3.Do analog thresholds calibration run (set SDAQ Parameters for analog thresholds calibration run, download crate, make run with the help of taker) 4.From VRBCR menu: a) check database b) new ft peds if you are calibrating cft : crate 50 c) new ft peds, new cps peds if you are calibrating cps: crate 51, 52 d) new fps peds if you are calibrating fps: crate 53 5.From VRBCR menu: write peds_zeroThrs to afpga 6.Download standard bias, as in 1) but with bias_offset set to 0.0 7.Do analog thresholds calibration run (set SDAQ Parameters for analog thresholds calibration run, download crate, make run with the help of taker) 8.From VRBCR menu: check database, new thresholds 9.From VRBCR menu: write peds_thrs to afpga 10.Restore bias by setting bias_offset to 0.0V, update bias, On bias You can write constant value to cft and fps pedestals in database by clicking on update ft peds to AFE2_pedestal. x7f results in pedestals around 55.

The procedure is following: 1. Decrease bias by 4.0 V a) Set bias_offset to –4.0V (in SVX Parameter menu, reachable from global parameter button) b) From VRBCR menu: update bias c) From VRBCR menu: On bias 2. From VRBCR menu: increase Tript vthresh, do this 7 times (at cts set discriminator thresholds to xdc=220) 3. From VRBCR menu: download Tript vthres 4.With the help of AFE menu (global parameter->AFE Parameter->AFE2_threshold) set AFE2_threshold to xa0 (for cps threshold should be x12) 5.From VRBCR menu: write peds_AFE2thrs to afpga 6.Set parameters for sdaq run as shown on page 30 7.Download crate by clicking on download in cft_gui 8.From VRBCR menu: set EPICS passive 9.Close AFE monitoring script 10.Do sdaq run with the following settings: a)trigger: led/led-0x b)set appropriate registers in trigger framework for triggering on Xing 63.

Quit cft_gui Restart cft_gui Open VRBCR_x menu: Click update bias, On bias. For left handed boards click also on temperature control off, temperature control on.

64. 21 November, 08, jadzia warchol, ext. 8341, phone 357-4232 64 Transferring Calibration To Off-line Database Transfer calibration constants to off-line database from cft_gui. For crates 0x50, 0x51 and 0x52 (Crate 0x53 is fps crate and transfer to off-line is done by Anatoly Evdokimov) click on the following: 1. update thresholds in CFT_PEDESTALS, for crates 0x51,0x52 and 0x53 2. insert offline PED 3. insert PE thresholds 4. insert offline THRS 5. update previous Run number in offline calibration database is the same as run number in SVX_RUN_NUMBER in VRBCR database parameters, as long as run_number in SDAQ Parameter page is smaller than 1000. Otherwise run number in offline data base is set to RUN_NUMBER in SDAQ Parameter page (reachable in cft_gui from global parameter).

65. 21 November, 08, jadzia warchol, ext. 8341, phone 357-4232 65 Transferring Calibration To Off-line Database Transfer to offline for CPS/FPS is done by Anatoly Evdokimov. You need to send e-mail to Anatoly with run number (s). CPS and FPS are readout by crates 0x51, 0x52, and 0x53. Crates 0x51 and 0x52 readout CFT and PS, crate 0x53 reads out FPS. This e-mail needs to be sent after you did item 1 on previous page (update thresholds in CFT_PEDESTALS for crates 0x51, 0x52 and 0x53)

66. 21 November, 08, jadzia warchol, ext. 8341, phone 357-4232 66 Transferring Calibration To Off-line Database You do not need to read this page to do the transfer. The data are transferred for run# that you get by right clicking on VRBCR_x and clicking on calib_run_svx. calib_run_svx is updated after calibration of analog thresholds when you click on new thresholds. So you do not need to do anything. However you could change calib_run_svx by writing New value and clicking on Modify Database.

69. 21 November, 08, jadzia warchol, ext. 8341, phone 357-4232 69 CPS MIP Calibration, 3/27/09 CPS MIP calibration run needs 2 million triggers, if muon system is not working rate of useful tracks decreases buy 3 therefore one needs three times more triggers. Not working calorimeter is okay. CPS MIP calibration is done with collider data after reprogramming CPS tripts to high gain, and reprogramming AFPGAS so that the pedestals are at ~55 ADC count (8 for standard CPS configuration). The whole process consists of 4 following steps: 1. Between stores CPS tript gains are set to maximum by writing 7 to gain register, and CPS pedestals are set to 55 by writing 127 to AFPGAS for the value to be subtracted from ADC counts. SDAQ threshold calibration run is taken with noise of 20%. 2. Return to standard CPS configuration since most probably CPS MIP run will not follow immediately SDAQ run. 3. CPS MIP in store calibration run with settings as in point 1 and CPS thresholds from calibration run in point 1. Here one allows that CFT was re-calibrated after run in step 1, this is non-standard since until now one crate was always calibrated in one run. 4. Return to standard CPS configuration. Effort was made to optimize time needed since setup in points 3 and 4 will waste collider data nevents_noise is set to 2000.0 for 20% noise

The meaning of bits is following: q_inj =xy x is fine time tuning y is charge magnitude y = xf =1111 large charge injected to both tripts y = x5=0101 small charge injected into both tripts y = xa=1010 medium charge injected into both tripts
