Bug #1030

Loop 3 gives us more yields 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 fam 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. ===== Loop 2 comparison to DIS simulation (see attached plot) x_60_2 Beginning of December 2023 (no dummy target data for PS4) x_60_4 Beginning of February 2024 (dummy target data for PS4 data) ====== Loop2 target cell wall: data taken during vaporisation https://logbooks.jlab.org/entry/4293900 vaporisationhttps://logbooks.jlab.org/entry/4293900
