single particle track

[fengxinyuan]

Dear Didier:

i want to track a single particle's motion in SC linac lattice in multiparticle calculation, how can i get it's coordinate in .dat file or other source?

sincerly,
Feng XY

Dear Fen XY,

If you only want to simulate a single particle, this is no longer a multi-particle calculation but a simple envelope calculation, where your particle is represented simply by the centre of gravity of the envelope. In this case, you can use the envelope plots to save the displayed trajectory to a file.

Dear Didier:

I want to track one of multiparticle's motion, not a single particle, to draw a Poincare surface. is there any solution?

Dear Feng XY

Ok attahced a video showing how doing that
