Date | Detector | Gain mode | Photon source | Photon energy | Gain HDF5 |
---|---|---|---|---|---|
2016-02-16 | DsaCsPad | high | Iron K-alpha (6.8keV4keV) | 7.2keV | |
Note: CsPad has high and log gain modes. A factor of 7 is used to recalibrate the high gain to low gain, e.g. 28 ADU at high gain results in 4 ADU at low gain.
Calculation note: At 8keV, we expect around 30 ADUs per photon in high gain mode. At 6.4keV, we are seeing around 23 ADU per photon. currentADU/currentEnergy*8keV=23/6.4*8=28.75 ADU per photon which is close to 30 ADUs.
