Requirements to meet:
Requirements | Measured result | note | |
---|---|---|---|
Mode of operation | AHL (functional) | Verified | |
AML (functional) | Verified | ||
FH (functional) | Verified | ||
FM (functional) | Verified | ||
FL (functional) | Verified | ||
Pixel size | 100x100 um2 | Verified | |
Range | Autoranging: >40000 keV (transitions 400 keV/1200 keV selectable) | ||
FH >400 keV | |||
FM >1,200 keV | |||
FL > 40,000 keV | |||
Noise r.m.s. | <~400eV (110 e- rms) |
Note that the specifications must meet the requirements at a readout rate that exceeds 5102 Hz or 4644 Hz.
Calibration Routine:
Calibration constants and how we determine them (TBD):
Pedestals:
Gain mode | Measurement | Calculation | Note |
---|---|---|---|
FH | Direct measurement of dark | average of 1000 events? | Takepeds |

FL | Direct measurement of dark | average of 1000 events? | Takepeds |
AHL-H | Direct measurement of dark | average of 1000 events? | Takepeds |
AHL-L | |||
AML-M | Direct measurement of dark | average of 1000 events? | Takepeds |

Gains:
Gain mode | Measurement | Calculation | Note |
---|---|---|---|
FH | Single photon data | Single photon data? | |
FM | FH single photon gain * linearity gain ration(FH/FM)? | ||
FL | FH single photon gain * linearity gain ration(FH/FL)? | ||
AHL-H | FH Gain? | is FH and AHL_H gains the same | |
AHL-L | FH single photon gain * linearity gain ration(FH/FL)? | is FH and AHL_H gains the same | |
AML-M | FH single photon gain * linearity gain ration(FH/FM)? | is FH and AHL_H gains the same | |
AML-L | FH single photon gain * linearity gain ration(FH/FL)? | is FH and AHL_H gains the same |
