CEA Codes forum

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?

Dear didier:

how did the phase advance data in tracewin.out or partran.out file calculated? i find the value is in deg/mm instead of deg/m, and seems not the same with phase advance in charts-phase advance-beam. And what the difference between kz and kr?

Dear didier,

thank you for reply, and may i ask , is the traceWIN's match arithmatic genetic algorithm?

dear Didier: I got two questions when i try to rematch the cavity failure situation. First, i couldn't find out how to isolate constraint the energy spread or phase spread. i already find DIAG_SIZE can set wanted rms phase spread, but this commend also need to set X and Y size. My second question is...
