Hello, I am studying a line for looking the effect on bunch length with CSR and without CSR. In this line, R56 is set to -0.25m and a chirped beam (chirping 0.4 is used). The initial bunch length is 8 ps. Bunch is tracked once with CSR is ON (Bins=500, Particles=500000) through lattice file "TL2_pr5...

Dear Sir,

Thanks for help...

Dear Sir, I am thankfull for your reply. It worked well..... When I increase the N_KICKS, does programme generates bunch length and wake field in *.wke files after each kick i.e. I think magnet is simulated like ---DRIFT-KICK1-DRIFT-KICK2-DRIFT-KICK3-......KICKn-DRIFT and on each kick (for N_KICKS=n...

Dear Sir, I am attaching .ele and .lte file and also .fin file generated by programme. All the .wke files are bigger in size ( more than 100 kB), so I did not attache those files. Perhaps at somewhere I am making some mistake but could not pin point it......... (I am running programme on Windows-7)....

Hello, I am trying to track a beam in a ~40 m long transfer line for a certain tuning of R56. Beam is generated through bunched_beam command (~8 ps). I defined drifts as CSRDRIFT in lattice file with "CSR_ON" option. Chirping is set to 1/R56 for compression. I am getting a message during run as " in...

Thanks Michael for reply and clarifying the things......

Hello, I am trying to use Elegant for tracking beam from a single magnet (later on to see the effects of CSR). But perhaps, I am not able to provide the correct beam energy in input file. I want to provide the beam (electron) with 300MeV as an input (from other file using SDDS_BEAM command in 6-D). ...

Thanks Michael!!!

In conversion from MAD to Elegant, the edge effects were not converted correctly by me in file for rectangular bends.... Now results are matching....

Hello, I am computing R56 for a transfer line using Elegant (without CSR) and the result obtained is -0.539m for a particular optics. For same optics MAD8 provides R56=0.30m. Sign is anyway different due to MAD conventions (-ct). The electron beam energy is 300MeV, so beta (relativistic) can not bri...

Thanks Bob & Michael......It worked nicely.......
