> Faraday cup readout at the end of our chamber should change based on whether or not the target is in and also the 59Cu 
beam energy.
> 
> The effect could be as much as 10 to 20%.  At some point, we should check the Faraday cup reading with the CH2 target 
and with the empty target.

For comparison, csd predicts 5.00MeV/u 59Cu?+ -> 4.66MeV/u 59Cu24+ following the 0.5mg/cm2 (CH2)n target
