no momentum-spread increase in several CSRDRIFTs with LSC on
Posted: 18 Jun 2020, 22:55
In my Linac tracking simulation, momentum spread does not increase in many parts
having several consecutive CSRDRIFTs with LSC on.
This is an example for case of no momentum-spread(s6) increase.

Drift space elements such as L200, L186 and L5 are defined as
L200: CSRDRIFT,L=0.2,DZ=0.05,USE_STUPAKOV=1,LSC_BINS=100
Is this result reasonable?
The Elegant versions I used are both 2020.2.0 and 35.1.0. The result is not changed.
Thank you in advance.
