Checklist for remote analysis shifts


Step 2/3

Please check the following parameters and values:




General information:

First run
Last run



Checks on Adei:

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)?



Checks on brew:

Parameter What to look for good (green)
or bad (red)
Comment if bad
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).
