PFILTER

An element for energy and momentum filtration.
Parallel capable? : yes
Parameter Name Units Type Default Description
DELTALIMIT   double -1 maximum fractional momentum deviation
LOWERFRACTION   double 0.0 fraction of lowest-momentum particles to remove
UPPERFRACTION   double 0.0 fraction of highest-momentum particles to remove
FIXPLIMITS   long 0 fix the limits in p from LOWERFRACTION and UPPERFRACTION applied to first beam
BEAMCENTERED   long 0 if nonzero, center for DELTALIMIT is average beam momentum
BINS   long 1024 number of bins
GROUP   string NULL Optionally used to assign an element to a group, with a user-defined name. Group names will appear in the parameter output file in the column ElementGroup
