SCRAPER

A collimating element that sticks into the beam from one side only. The directions 0, 1, 2, and 3 are from +x, +y, -x, and -y, respectively.
Parallel capable? : yes
Parameter Name Units Type Default Description
L $M$ double 0.0 length
XO $M$ double 0.0 radiation length
ENERGY_DECAY   long 0 If nonzero, then particles will lose energy due to material using a simple exponential model.
ENERGY_STRAGGLE   long 0 Use simple-minded energy straggling model coupled with ENERGY_DECAY=1?
NUCLEAR_BREMSSTRAHLUNG   long 0 Model energy loss to nuclear bremsstrahlung? If enabled, set ENERGY_DECAY=0 to disable simpler model.
ELECTRON_RECOIL   long 0 If non-zero, electron recoil during Coulomb scattering is included (results in energy change).
Z   long 0 Atomic number
A $AMU$ double 0.0 Atomic mass
RHO $KG/M^3$ double 0.0 Density
PLIMIT   double 0.05 Probability cutoff for each slice
POSITION $M$ double 0.0 position of edge
DX $M$ double 0.0 misalignment
DY $M$ double 0.0 misalignment
INSERT_FROM   STRING NULL direction from which inserted (+x, -x, +y, -y)
DIRECTION   long -1 obsolete, use insert_from instead
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
