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 ...

Dear Wai-Ming,

For example the Janathan's map:
FIELD_MAP 100 .1 -90 30 1 1 0 0 test

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.

Firstly, it ...
