STRAY

A stray field element with local and global components. Global components are defined relative to the initial beamline direction.
Parallel capable? : yes
Parameter Name Units Type Default Description
L $M$ double 0.0 length
LBX $T$ double 0.0 local Bx
LBY $T$ double 0.0 local By
GBX $T$ double 0.0 global Bx
GBY $T$ double 0.0 global By
GBZ $T$ double 0.0 global Bz
ORDER   long 0 matrix order
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





This element simulates stray fields. These fields are considered perturbations, in that they change the trajectory (or orbit), but not the floor coordinates. Local stray fields (LBX and LBY) are referenced to the local coordinate system. Global stray fields (GBX, GBY, GBZ) are referenced to the global coordinate system, which coincides with the local coordinate system only at the start of the beamline (unless there is no bending, in which case the two systems are identical).
