When changing flux for FSEE, you'll want to first use the MHB and attenuators to make adjustments.

If you are going to change to a low flux around 1E3 pps/cm2, then you'll want to follow the steps below:

  -  Switch FC_1102 cup to tetram reading on the FC Overview page.
  -  Calculate the amount of flux needed on FC_2596 by using the calculator on the FSEE GUI. 
  -  Measure current on FC_2596 and record the current reading. Do the same on FC_1102.
  -  Calculate the ratio between the FC_1102/FC_2596. Multiply this ratio and the desired up reading on FC_2596. This will be the reading you'll want to attain on FC_1102.
  -  Put the beam back onto FC_1102 and adjust attenuators/the MHB to achieve the calculated value from the step before.
  -  Insert the viewer to perform another uniformity measurement. 
  -  Send flux to the users /calibrate the jaws.
  -  Beam is ready.
