Thank you!

Maybe the command "Select particles outside ellipse" is also necessary?

For example, how to select particles inside ellipse both in xx' and yy' planes?

Didier,

Thank you!

About the ellipse selection, how about cutting it according to the edge defined in "Charts - Output - Options - Emittance ellipses"?

Thank you very much for the DIAG_PHASE_ADV command. It helps me a lot in beam physics design. And another function is useful to me: the same size or beta function for X and Y. For example, I need a beam waist at a position, which could be set by "DIAG_WAIST" or "DIAG_TWISS". At the same time, I need...

Hi Didier, For beam distribution, right-clicking for "select particles" is a powerful function. I think some improvement could be added if possible. 1. Rescale the coordinate range to a required region, e.g. from 10 to 100, and "select particles", the selected region is a little larger than what we ...

Hi Didior,

How about the command "DIAG_PHASE_ADVANCE"？

Something wrong with the attachment. I just put the code here: DRIFT 0 50 DRIFT 0 50 DRIFT 0 50 DRIFT 1000 50 ADJUST 1001 2 0 -18 18 QUAD 200 15 50 0 0 0 0 0 0 DRIFT 100 50 ADJUST 1001 2 0 -18 18 QUAD 300 -15 50 0 0 0 0 0 0 DRIFT 100 50 ADJUST 1001 2 0 -18 18 QUAD 200 15 50 0 0 0 0 0 0 DRIFT 1000 50...

Dear Didier,

Seems it doesn't work correctly. Could you help to check it?

Attached the project file.

I noticed the upgradation. Thank you very much!

Dear Didier, Thanks for the reply. In beam transport line design, generally, more than one type of beam parameters should be considered, including bean size, achromat, twiss parameters, phase advance, matrix elements, etc., so "DIAG_SIZE_MAX" is important to me. Is it possible to add that? Kinds, sh...

Dear Didier, I'm wondering if it is possible to add some commands about beam parameters' matching: 1. Boundary limit about command "MATCH_FAM_GRAD". 2. "SET_SIZE_MAX" is a quite useful command in beam transport line design. If "DIAG_SIZE_MAX" is added, it would be much more convenient. 3. "DIAG_WAIS...
