Hi Emmanuel,

As usual, what doesn't work for you works for me, making it difficult to correct what does work.

Dear Li,

This is the length (mm) of the bunch.

Dear shliu,

It's fixed.

Dear Wai-Ming, I agree with everything you wrote, except "the RF phase" does NOT depend on the length of the fieldmap. Whichever option you choose for parameter#10, if you set a synchronous phase value, the RF phase will necessarily depend on the field in the cavity, i.e. minimally on its length. In...

Dear Pedro,

Indeed, I see the problem.
It's been corrected in the latest version available on the site

Dear Pedro,

Please show me your example, because on my side everthing seems ok (see below)

Dear Wai-Ming,

Could you be more specific, as I've compared the latest version with the one from 6 months ago and I can't see any difference, except for the name of the RF phase.

Dear Jeroen, As can be seen from your simulation below, a certain number of particles are detached in energy, making the longitudinal emittance larger and larger, until one of them is lost on the wall of the RFQ, abruptly resetting the emittance to a lower value. To overcome this problem in calculat...

Dear Pedro,

This is obviously not the behaviour that is expected, of course the distribution is not lost and it is only the average energy that is affected. Could you send me your example, because what you're indicating isn't normal and I don't observe that.

Didier
