CSRDRIFT

A follow-on element for CSRCSBEND that applies the CSR wake over a drift.
Parameter Name Units Type Default Description
L $M$ double 0.0 length
ATTENUATION_LENGTH $M$ double 0.0 exponential attenuation length for wake
DZ   double 0.0 interval between kicks
N_KICKS   long 1 number of kicks (if DZ is zero)
SPREAD   long 0 use spreading function?
USE_OVERTAKING_LENGTH   long 0 use overtaking length for ATTENUATION_LENGTH?
USE_SALDIN54   long 0 Use Saldin et al eq. 54 (NIM A 398 (1997) 373-394 for decay vs z?
SALDIN54POINTS   long 20 Number of values of position inside bunch to average for Saldin eq 54.

SPREAD_MODE   STRING full full, simple, or radiation-only
WAVELENGTH_MODE   STRING sigmaz sigmaz or peak-to-peak
BUNCHLENGTH_MODE   STRING 68-percentile rms, 68-percentile, or 90-percentile
SALDIN54_OUTPUT   STRING NULL Filename for output of CSR intensity vs. z as computed using Saldin eq 54.
OL_MULTIPLIER   double 1 factor by which to multiply the overtaking length to get the attenuation length
