The annihilation counter observed 1 e+ for every nA of electrons beam.  I was not sure what the compton polarimeter is observing given the large background.
Use the above to predict our rate if we run the HRRL at 80 mA peak current with 50 nsec wide pulses and a rep rate of 300 HZ.


In PEPPo: <math>1~nA = 10^{-9}~C/s<math> -> 1 nC e- makes 1 e+

In HRRL: 80 mA, 50 ns pulse width, 300 Hz reprate:
