what is the exit velocity?
I would think there would be quite a spread of speeds, partly from the thermal Maxwellian speed distribution of the ions, but also their orientation to the E & B fields. But the peak would still be around the peak of the thermal distribution. So at 100keV the speed is ~2000km/s or 0.007% of c. Rising to 5400km/s at 600keV
