Dear Michael,
thank you for your reply. Right, I have also thought of doing that. I think it will do the trick for my purpose.
Best,
Martin

train of bunches with different charge
Hi Michael and others, I would like to use a train of bunches, each bunch represented by one macro particle but with different charge. Is that possible? I have created sdds files (to be used in sdds_beam), similar as in the example CBI. It has a parameter "Charge" for each page. Does it define the t...

Re: many-turn tracking with time dependent modulations
Dear Michael,
yes you are absolutly right! I misinterpreted the meaning of s. St is the quantity I wanted and it gives comparable results for both change_t=0 and 1. Thank you for your help!

Re: many-turn tracking with time dependent modulations
I attached the input files (it is a modification of the PAR/bunchLengthening example). And a plot of sigma_s of the tracking once with change_t set in the cavity and once without. It seems the black curve is the wrong one, is it not? The thing is, I'd like to look at the bunch length while applying ...

Re: many-turn tracking with time dependent modulations
Thanks for your replies. The problem I have occurs in an electron storage ring with synchroton radiation. The components are basically: a ring with 1st order matrix elements, a cavity (RFCA with change_t=0), and sychroton radiation: sr: sreffects, damping=1, qexcitation=1, losses=1 The result is tha...

many-turn tracking with time dependent modulations
Dear all, I intend to do many-turn ring-tracking with time dependent modulation of some elements. I run into this bug with numerical errors in the longitudinal position. The bug does not occur if I set change_t=1 in one of the cavities (RFCA). However I then have no time depenance and cannot use com...
