Re: rfmode element in a active harmonic cavity
Chao, I'm glad to hear that you are now getting the same results as elegant after finding a problem. I'll look into the KAverage issue. To vary the charge per bunch in elegant, at present you have to vary the number of particles per bunch. The reason is that elegant assigns the same charge to each m...

Re: ~10x Speed up for multi-bunch studies with short+long range impedance
I think this is a perfectly legitimate approach and will see how it can be implemented in the code in a flexible fashion. A very easy way is just to provide START_PID and END_PID parameters for the short-range wake elements. There is an alternative, use of pseudo-multi-bunch mode, but that assumes t...

Re: rfmode element in a active harmonic cavity
Chao, I don't do anything special to control noise. My algorithm is similar to what you describe: I make weighted sums of the quantities for each bin. I do this for real and imaginary components, then compute the phases from the average values. I'm not sure why a discrepancy develops as the simulati...

Re: rfmode element in a active harmonic cavity
Chao,
Yes, that is a good description of what we do.
There's also a "binless" mode that uses the individual particles to do the same thing. It's pretty slow but can be used for checks.

Re: TRWAKE on the beam
Simona, Elegant's method is as follows: 1. Create a position-weight charge histogram. This gives Q *<x > for a series of slices i, where Q is the charge in the slice and <x > is the average position in the slice. 2. Convolve the weighted charge histogram with the Green function, giving the transvers...

Re: sddsanalyzebeam Twiss parameters
Adam, The discrepancy appears to be due to strong chromatic effects. If I convert the entire lattice to use matrix-based tracking (SBEN, QUAD, SEXT), then set default_order=1 in run_setup, the beta functions agree between max4.twi and max4.sig. However, if I set default_order=2, the discrepancy appe...

Adam,
Can you provide the file input/BC2.W-INIT and any other input files I might need to run this?

Re: Optics with AC skew
Zeus,
Inclusion of an MBUMPER element will not affect the computed values of any of those parameters, since it is time-dependent.
