Here is the rest of the proton ring beam and maxwellian proton background for the case of particle injection of the ring beam:

values in input.h:
ntimes= 400 dtwci= 0.1 nx=256 xmax=256 wpiwci=10000. nsp = 2 nspec(1)=5120 nspec(2)= 10240 vbspec(1)=-0.15 vbspec(2)=9.85 dnspec(1)=1.0 dnspec(2)=0.02 btspec(1)=1.0 btspec(2)=1.0 anspec(1)=1. anspec(2)=1. wspec(1)=1.0D0 wspec(2)=1.0D0 add_no(1) = 0. add_no(2) = 2.0e-5*nspec(1)*1200 bete=1. resis=0. theta=0. iemod=0

The add_no(k) parameter species the loading rate. So no ions are added for the background species, but for the beam, the loading rate given is equivalent to ~12 ions/timestep or about 5000 ions over the course of the run. 20 ions/cell are loaded in the beam and background at t=0, so the beam density is almost doubled at the end of the run.

Here are the results:

1) Phase Space (red = background fixed, black = beam injected)
2a) Velocity Space	2b) Velocity Space
3a) By	3b) Bz
3c) Phi
4) B field energy
5) Fourier modes
