Bug #1030

Updated by Julie Roche 7 months ago

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.
