| gain | charge injection | current default | measured (ADU / keV) |
|---|---|---|---|
| L | 0.46 | 0.01 | 0.139 |
| M | 15. | 0.3(3) | 4.5 |
| H | 46.7 | 1 | 13.9 |
Gain factors default vs charge injection
- Detector/examples/ex_epix10ka_images.py
- XcsEndstation.0:Epix10ka2M.0
- charge injection gain factors were generated from exp=xcsx35617:run=544
- data with water ring for comparison exp=xcsx35617:run=528
- account relative factor 46.7
- selected rect [6, 120:170, 200:250]
gain default: H / M / L = 1 / 0.33333 / 0.01
gain from charge injection:
| constants | Mean | RMS | RMS / MEAN |
|---|---|---|---|
| default | 1117.7 | 62.72 | 0.05618 |
| charge injection | 1177.5 | 66.79 | 0.05672 |
Conclusion: in this test charge injection gainci constants do not improve gain factors comparing to default
