Gain and time calibrations for waveform. DST3 → DST4: Extract photons. TTree not for channels but for photons. Divide to eXXrYYYYpZZ.dst3 if the size is larger than about 2 GB (maybe larger than 2000 events). eXXrunYYYY.dst4 (photon data, etc.) Divided eXXrYYYYpZZ.dst3 are combined.

Setup

PCs at FNAL PC1 (Hawaii) Rawdata. PC2 (Hawaii) Rawdata, DST1, DST2. PC3’s (Hawaii and Nagoya) Rawdata, DST1, DST2, DST3, DST4.

Waveforms for DST1 and DST2 Input sine wave (80 MHz) to PMT 1 of module 0 and 1. Pedestal subtraction seems to work well: left. If a bias voltage Vdly in the ASIC is different btw sine-wave data and pedestal data: right.

Waveforms for DST1 and DST2 Input sine-wave (80 MHz) to PMT 1 of module 0. Gain dependence on channels. Will be calibrated at DST2 → DST3. ASIC column ID = 3ASIC column ID = 2ASIC column ID = 1ASIC column ID = 0

Waveforms for DST1 and DST2 Input sine-wave (80 MHz) to PMT 2 of module 0, 1, and 2. Time dependence on channels (seen when different feed-back conditions are used?). Will be calibrated at DST2 → DST3. Module 0Module 1 Module 2

Pedestal subtraction for good channel Mean = -1.7 RMS = 3.1 (Single photon > 50) Pedestal subtracted using independent pedestal data. Pedestal distribution.

Pedestal subtraction for bad channel Not stable for some windows of ASIC.

Pedestal subtraction for bad channel 2 Mean = RMS = Similar for many channels for module 0. Will make bad-channel list to remove in the analysis.

pedestal − pedestal (same file) If the same pedestal data is used for the pedestal subtraction of a data, Script itself is working well.

DST2 and DST3 A temporary calibration (only for the time, + 2 for even samples) is applied. At samples around 64, 128, and 192, we see some structures (related to characteristics of ASIC)... Will calibrate or remove these samples. Still need more works for the calibration. Files of DST3 will be updated time by time.

Charge calibration Strategy Use sine-wave data (80 MHz). Integrate absolute ADC values over events for which different phases of the sine-wave are applied. Status Making codes. Still need more works...

Time calibration Strategy Use zero-crossing method for odd and even windows. Need an independent treatment on odd and even samples. Time difference between odd and even samples should be calibrated (need to establish method). Time difference between different channels should be calibrated (need to establish method). Status Making codes. Still need a lot of works...

For obtaining DST4 Threshold-type photon search is applied currently. Example of waveform which has photon hit candidate (threshold is set to −50). Still need more works for the calibration. Files of DST4 will be updated time by time. Hit candidateMultiple-hit candidate exp 0 run 43 (for up to 2000 events)

gif animation exp 0 run 43 (for up to 2000 events)

DST4, NData Some channels (bad channels) always find hits. exp 0 run 43 (for up to 2000 events)

DST4 (HV only for module 0) NData dependent on ID’s and time distribution. Bad channels... exp 0 run 43 (for up to 2000 events)

Link to a temporary server Several (if possible all) DST4 data will be uploaded to u.ac.jp/~yhorii.nagoya/belleii/top/beam_test11/data/dst4/
