| Subsystem | What to look for | good (green) or bad (red) |
Comment if bad |
|---|---|---|---|
| High Voltage (K65) |
Are there any unexpected spikes in the
K65 readback.
(more details can be found here) |
||
| High Voltage (absolute tank potential) |
Are there any unexpected spikes in the
tank potential readback.
(more details can be found here) |
||
| BIXS | Is the BIXS singal
stable? If not, something is wrong.
Is there a long term trend visible? | ||
| Tritium throughput | Is the tritium throughput
stable to within < 1 sccm? If not, something is wrong.
Is there a long term trend visible? | ||
| FBM | Check for outliers in the FBM rate. Absolute values depending on pixel and KNMx period, keep in mind long term drift. Just check for outliers!. | ||
| RW current and voltage | Were the IU scans performed regularly (visible in the RW current and voltage)? |
| Parameter | What to look for | good (green) or bad (red) |

|---|---|---|---|
| Run Length | Do any runs have shorter run length? Shorter length indicates missing subruns. | ||
| Data Size | Do any runs have a different data size? Smaller size indicates missing subruns. | ||
| FPD Energy Shift | Peaks in BREW plot of this value over time indicate rapid detector gain drifts, likely caused by large temperature changes of the building. |
||
| Grid-Sync Gap | Non-zero values indicate dead-time in DAQ. | ||
| Rate 300eV | Is rate 300 eV comparable to other runs? (necessary for Column Density Calculation). | ||
| Rate 90eV | Is rate 90 eV comparable to other runs? (necessary for Column Density Calculation). | ||
| Tritium Purity | Is tritium purity estimated and around 98.6%? (necessary for Column Density Calculation). |
