moments_output command on Win system
Hi, I am running elegant(Version 2020.4) on Win10 system, the output file of moments_output is empty, the script I tested was in the path :elegantExamples\examples\PAR\moments, which I download from the elegant manual website. When I run the script in the terminal, the output message is like the att...

Re: beam-ion effect
Hi, Have spend a lot of time to debug the code (during the last several weeks), and suddenly I have realized the problem in the beam-ion effect simulation with the "quesi-strong-strong' model. It is discussed by several researchers that the ions distribution will not with a Gaussian type, where as i...

ion Effects Simulation
Hi, I used the ion_effect command and IONEFFECTS element to simulated the effect of residual gas on beam quality.I used the earlier version(I forgot the version number,maybe elegant 34.3.1),I could get some information,like the ion number increase as the increase of tracking turns.But when I update ...

beam-ion effect
Hi Recently, I am trying to make a C++ programme for for beam-ion effect simulation. As the first step, I actually follow the approaches used in Elegant. The main steps can be descried as follows (take the weak-strong mode for example). The index k is used to specify the interaction point and the in...

Re: Bend with misalignment
Hi Michael, I set the E1 and E2 in CSBEND (E1=E2=ANGLE/2),I upload the files I use!The command used like this: elegant bend.ele -macro=L=1.0972538663939300,ANGLE=0.0238688451731700,E1=0.0119344225865850,E2=0.0119344225865850,DX_B1=0.0003000000000000,DY_B1=0.0,DZ_B1=0.0,TILT_B1=0.0,DX=0.0,DY=0.0,DP=0...

Bend with misalignment
Hi Michael, I confirmed the transmission model of bend with single particle tracking,when I set the DX of CSBEND with different values,the output as show in the uploading attachment。The particle initial coordinate at entrance is [0 0 0 0 0 0],the coordinate at exit is plot in the attachment.The intu...

Re: How to calculate the real survey coordinate after a mis-aligned quadrupole
Hi, Michael Thanks a lot for your prompt reply. I almost understand your method but still one question. For getting the survey coordinate \Delta_y and setting Dy , what is the role of the column Y from the floor_coordinate option? I am afraid my previous description is no so clear. In my case, the s...

How to calculate the real survey coordinate after a mis-aligned quadrupole
Dear All, I am designing a fast kicker-septum system for the beam switchyard of a CW X-FEL. Electron beams are distributed by a series of fast-kickers in vertical direction and then pass though a DC Lamberson septum. Between the kicker and septum there are several quadrupoles for beam matching. Howe...

Re: Momentum Aperture without sextupole
Hi,Michael I follow your advice to check all the settings,I found there is one point where the settings is different.In one particle tracking model,I set the MALIGN element with dx=0,dy=0 and dp=0.013,but in the momentum_aperture model,I set x_initial=1e-6,y_initial=1e-6.I think in the momentum_aper...

Momentum Aperture without sextupole
Dear All: I want to tracking the Momentum Aperture for a lattice without sextupole to simulate the machine beam-tuning process.Without the sextupole,the chromaticity【dnux/dp (1/(2$gp$r)) = -2.159890e+02】and 【dnuy/dp (1/(2$gp$r)) = -2.921960e+02】 are so big!I used one particle tracking(by using the M...
