Re: Qxy calculation in Tracewin
Dear Rajni, First wish you happy new year. Qxy plot is the tune “Footprints” with Space Charge. This chart is calculated by determining analytically the coherent mode frequencies and plotting them on a spectral chart of single particle frequencies of a well-matched beam. An example is provided in Tr...

Re: Emittance blow up in RFQ_1 example
Dear Bruce, Happy new year. By default Toutatis excludes from rms emittance calculations the particles that are detached and far from the core of the beam. This is not the case in TraceWin, so at the end of the RFQ when you arrive in the DRIFT elements these particles are again included in the emitt...

Re: Multi frequency excitation
Dear Wai-Ming,
I also wish you a Happy New Year.
Don't worry about this message. If you save your project, it should not reappear.

Re: SPACE_CHARGE_COMP and field_map
Dear Changqiang_ciae, That's exactly right, in tracking mode, when you use field maps that curve the central trajectory the space charge is not calculated. This is a much more complex development than the usual space charge in rectiligne frame and it has not yet been carried out and implemented. Pro...

Re: Errors study on DTL_CEL element
Dear Michele,
1) DTL_CEL is considered as an element and not as a sequence of these individual parts.
2) Normally, a quadruple error consistently applied to the last quadruple of DTL_CEL(n) and the first half quadruple of DTl_CEL(n+1)
Best Regards,
Didier

Re: Multi frequency excitation
Dear Wai-Ming, First of all, the best way is obviously to use a real rebuncher field map. The field map example given by Jonathan is just a simple way to replace the use of the usual GAP element which could have problems due to too large transverse beam divergences. So seeing a discontinuity, which ...

Re: Multi frequency excitation
Dear Wai-Ming,
I'm not sure to undestand your question. Anyway, in all case field_map Tools from "Charts" tab-sheet allows to visualize the field shape used for computation.
For example the Janathan's map:
FIELD_MAP 100 .1 -90 30 1 1 0 0 test

Didier

Re: Multi frequency excitation
Hi,
Yes, Jonnathan is right, this could work using the GAP element, only if the transverse divergences of the beam are not too big. This problem is caused by the thin gap RF model used in TraceWin.
