ZLONGIT

A simulation of a single-pass broad-band or functionally specified longitudinal impedance.
Parameter Name Units Type Default Description
CHARGE $C$ double 0.0 beam charge (or use CHARGE element)
BROAD_BAND   long 0 broad-band impedance?
RA $Ohm$ double 0.0 shunt impedance
RS $Ohm$ double 0.0 shunt impedance (Ra=2*Rs)
Q   double 0.0 cavity Q
FREQ $Hz$ double 0.0 frequency (BROAD_BAND=1)
ZREAL   STRING NULL $<$filename$>$=$<$x$>$+$<$y$>$ form specification of input file giving real part of impedance vs f (BROAD_BAND=0)
ZIMAG   STRING NULL $<$filename$>$=$<$x$>$+$<$y$>$ form specification of input file giving imaginary part of impedance vs f (BROAD_BAND=0)
BIN_SIZE $S$ double 0.0 bin size for current histogram (use 0 for autosize)
N_BINS   long 128 number of bins for current histogram
WAKES   STRING NULL filename for output of wake
WAKE_INTERVAL   long 1 interval in passes at which to output wake
AREA_WEIGHT   long 0 use area-weighting in assigning charge to histogram?
INTERPOLATE   long 0 interpolate wake?
SMOOTHING   long 0 smooth current histogram?
SG_ORDER   long 1 Savitzky-Golay filter order for smoothing
SG_HALFWIDTH   long 4 Savitzky-Golay filter halfwidth for smoothing
