CEA Codes forum

Dear Didier,

i notice a bug in energy plot. In energy chart, before i click option bar, the output is wrong, but after click it suddenlly right, as shown in video.

ok i understood now. thank you!

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 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

by this chapter, i can draw pictures like this. but there cannot show input beam. How to add real beam into this acceptance? is copy the beam data into txt file?

Dear Didier:

I see some of the diagrams also depict both acceptance and input beam in longitudinal phase space, and I couldn't find the drawing method in the manual. May i ask how to draw that?

oh, i just find the fault. i set a negative value to betaz by mistake, which make code crashed.

thank you!

dear Didier:

Why is the filename sometimes partran.out and sometimes partran1.out when I use tracewin in batch command?

Thank you!

I was using a spoke cavity by field_map element and the element been seperated into 9 pieces, each phase advance is different. In each piece is the phase advance calculate by the integral of 1/beta function?
