Electron and Positron beams generated with DEFAULT JPF witr.py beamfile generator, run through lem.py for beam diagnostics, and used with JPF base0.cfg (edited for increased duration and format of outputted results).

A positive q/m is obtained by changing the sign of the bunch charge in witr.py and the sign of Qw (hmmmmmm)

Run Number Driver Description Base Configuration Window Width Window Length q/m Total Weight (pC) LCODE ampl LCODE Beam Current LCODE Beam Length Beam Length (um) Energy (approx) (MeV) Comments
1 electron base0.cfg (JPF) 3.84 10 -1.0 -49.980500 n/a n/a n/a 59.755747 150 Result as expected, but need to run over greater plasma depth.
2 electron base0.cfg (JPF) 3.84 100 -1.0 -49.980500 n/a n/a n/a 59.755747 150 Longer run.
3 positron base0.cfg (JPF) 3.84 100 1.0 49.976500 n/a n/a n/a 60.038280 150 Identical to electrons which isn't right. Just changing bunch charge sign for next run in case of cancelling effect?
4 positron(?) base0.cfg (JPF) 3.84 100 1.0 49.976500 n/a n/a n/a 59.844681 150 test
