Summary
| Configuration | Bias | Trigger source | Radiation source | Shield | Amount | Notes | Rows |
|---|---|---|---|---|---|---|---|
| 2-sided | 0V | SiHV | Am only | Partial | 3.3 hours | Data at three different Am source positions | |
| Side2 | scan 0V up to -238V | SiHV | Am only | Partial | 19 series | ||
| Side2 | 0V | SiHV | Na-22 | Partial | 2 series | NaI coincidence tests | |
| Side2 | 0V | SiHV, NaI | PuBe | Complete except borax | 2 series | Test PuBe paraffin drum at two positions | |
| Side2 | 0V | SiHV, NaI | Am only | Complete | 2 series | Muon test. NaI trigger configured for muons. | |
| Side2 | -197V | NaI | PuBe | Complete | 61 hours | NaI window 7.6-11.2 MeV (before recalibration). But probably changed by accident during this dataset. | |
| In July 2022 we started having He-film problems. After this point we started taking data in ~2-day stretches with pumpouts between. | |||||||
| Also after this point the maximum bias on the detector is around -84V due to increased leakage after HV mishap. | |||||||
| Also the NaI amplitudes were recalibrated at this time. NaI trigger windows should be more reliable for data after this point. | |||||||
| Side2 | 0V to -84V | SiHV | PuBe | Complete | 5 series | “Ladder calibration” data. | 95-99 |
| Side2 | -84V | NaI | PuBe | Complete | 21 hours | NaI window 7.6-11.2 MeV | 101-108 |
| Side2 | various | NaI | PuBe | Complete | 5 biases | NaI window 7.6-11.2 MeV | 116-128 |
| Side2 | -81V | NaI | PuBe | Complete | 57 hours | NaI window 7.6-11.2 MeV | 129-147 |
| Side2 | various | NaI | Am only | Complete | 4 biases | NaI window 7.6-11.2 MeV | 148-158 |
| Side2 | -83V | SiHV | Am-only | Complete | 17 hours | Low trigger threshold (R68-style) | 159 |
| Side2 | -83V | SiHV | PuBe | Complete | 69 hours | Low trigger threshold (R68-style) | 160 |
| Side2 | -83V | NaI | PuBe | Complete | 41 hours | NaI window adjusted (7.6-11.0 MeV) to avoid saturation peak | 163-171 |
| Side2 | -82V | SiHV | Am-only | Complete | 43 hours | Low trigger threshold (R68-style) | 172-173 |
| Side2 | -83V | NaI | PuBe | Complete | 41 hours | NaI window 7.0-11.0 MeV | 174-181 |
| Side2 | -82V | NaI | PuBe | Complete | 70 hours | NaI window 4.73-5.93 MeV (may have been reset by mistake at some point) | 192-206 |
| Side2 | -82V | SiHV | PuBe | Complete | 23 hours | Low trigger threshold (R68-style). NaI coincidence data taken too, not sure if we did that with previous R68-style data | 211-213 |
| Side2 | various lower biases | SiHV | PuBe | Complete | 10 biases | Low trigger threshold (R68-style). | 215-233 |
| Side2 | -82V | NaI | Am only | Complete | 14 hours | NaI window 4.73-5.93, or 4.73-5.13? not sure | 234-236 |
Processing notes
All data has been processed with an initial processing configuration. Calculated templates are used with risetime/falltime chosen empirically to match lowest-amplitude phonon pulses (targeting lowest part of energy spectrum). Default phonon start-time chosen, which does not quite match phonon t0 in the case of NaI-triggered data.
