Process and current progress:
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 |
| FM | 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 |
| AML-L |
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 |
