Dear Didier,

Thank you. I'll try to use BEAM_ROT.

Dear Didier, Thank you for giving me nice information. I mean a kind of misalignmant of the solenoid, not rotation caused by the magnetic field. I would like to rotate the field map around x-axis because there is known misalignment(tilt) in reality. BEAM_ROT is a good way to modify the magnetic fiel...

Dear Didier, Hello, I would like to use 3D solenoid field map and add x, y shifts and θ_x ,θ_y rotations to the map. I think I should use "SUPERPOSE_MAP Z0 X0 Y0 θ Z0 θ X0 θ Y0", but nothing happened when I add x, y shift and rotation with SUPERPOSE_MAP. I have to use SUPERPOSE_MAP_OUT ? However, I ...

Dear Didier, Thank you for your kind reply. It helps me so much. I understand that z-rms must be specified in order to decide z-direction mesh size in PICNIR2D. When you said beta*lambda should be the same order than the transverse one, lambda = [speed of light]/[bunch frequency] is right ? And also...

Dear Didier, Hello, I'm trying to calculate beam transfer at LEBT with space charge effect. The beam is CW(I checked CW beam checkbox), so I thought "bunch frequency" in main tab does not affect the calculation. However, the simulated result completely change when I change bunch frequency (ex. from ...
