Stripper Efficiency is the amount of beam that passes through the
Lithium Stripper and
Charge Selector in
FS1, if the Stripper is turned off then we would have 100% efficiency as all beam would pass through, if it were tuned incorrectly and didn't allow any beam to pass through, then it would be 0%. Another way to think of it is what percent of the initial beam that makes it to the LINAC is the desired charge, if we want a charge state that's 70% of the beam then we'd want 70% efficiency, if we want an additional charge state that's 15% of teh beam then this goes to 85%.
