Bug #1030
Updated by Julie Roche 7 months ago
Loop 3 yields at 25 and 30 psia: https://logbooks.jlab.org/entry/4296639 and https://logbooks.jlab.org/entry/4296687
Loop 3 gives us more yields than Loop 2 at 11 uA for 58 and 42 Hz: https://logbooks.jlab.org/entry/4294810
No beam current dependence for Loop2 and Loop3 at 58 Hz: https://logbooks.jlab.org/entry/4295103. This feature is also seen in the target boiling data we took back in Sept 2023: https://redmine.jlab.org/issues/845#change-2067
Loop 2 - The issue is not an effect of the controller - https://logbooks.jlab.org/entry/4294867
Loop 2 - The issue subsides some when the fan is reversed, but running the fan reversed is unsustainable https://logbooks.jlab.org/entry/4292236
Loop2 yield decreases when fan speed increases https://logbooks.jlab.org/entry/4289172.
======
There might be a constant ztarget shape difference between LH2 and LD2 throughout the NPS data taking: https://logbooks.jlab.org/entry/4293600.
