I forget to mention that it is plot for RFQ only. Thanks to pointed reply, Can we also say that there is fast crossing of four lattice periods with tune depression more than 0.7 and therefore no significant effect on beam dynamics. I am counting yellow dots for Kz/Kxy = 1. What is the reason for it?...

In tracewin, if we wish to design extraction system using field maps, what is input energy of beam which can be taken ? For example, Can we take beam at plasma potential such as 100 eV energy?

Thanks, I shall try this command

I request you explanation of this Hoffmann Chart of the RFQ model. Can we say also that it is plot of σT/σ0T versus σz/σT? Can you please corelate the X and Y axis in this way. What is conclusion of yellow dots which is data from multiparticle simulations. I enabled all 4,3,2 order while plotting th...

Cannot find matching element commands
From->[PROCESS_MATCHING] : Family matching

This is the error coming if we use MATCH_FAM_FIELD

As per my experience, I have used MATCH_FAM_GRAD for electrostatic quadrupole also and it works very well.

I tried using command MATCH_FAM_GRAD, its not working here, not able to change Electric field intensity factor..It works for solenoids to vary magnetic field intensity factor. But here, I am using electric field map from POISSON code for einzel lens. Please suggest how to vary it to match next stage...

Can you elaborate what is delta s (mm) mentioned on 138 page no. what is its value when manually verifying the transfer matrix of one electrostatic acceleration line. It will be helpful if you can make a drawing depicting the various dimension mentioned for it?

ok thanks, so it is Energy of incoming beam (eV)/Aperture(mm2) = Transverse defocal ?

Please explain little more about TRANSVERSE defocal for electrostatic acceleration, There are two units mentioned eV/mm2 and eV/m2 on page 55 and 108. I have to use this option to define an einzel lens.

Please see the attached figure. If mismatch factor is 1% -> βx are multiplied by 1.01² means that transverse size is 1% bigger, Please suggest me if its correct or not ?
