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.

• Input sine-wave (80 MHz) to PMT 1 of module 0.

Gain dependence on channels.Will be calibrated at DST2 → DST3.

ASIC column ID = 3 ASIC column ID = 2 ASIC column ID = 1 ASIC column ID = 0










• 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 0 Module 1 Module 2







Pedestal subtraction for good channel



Mean = -1.7RMS = 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 = 14.65RMS = 42.14...

Similar for many channelsfor module 0.

Will make bad-channel listto remove in the analysis.

pedestal − pedestal (same file)

• If the same pedestal data is used for the pedestal subtraction of a data,



Script itself isworking 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.

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.

DST4, NData

• Some channels (bad channels) always find hits.


DST4 (HV only for module 0)

• NData dependent on ID’s and time distribution.

Bad channels...
