|ON_PASS||long||-1||pass on which to apply|
||modify the matrix even if on_pass=0|
|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|
The default value of the
PASS parameter (-1) means that the misalignment is
imposed on the beam every pass. This is appropriate for static misalignments.
When using the
MALIGN element to kick the beam for beam dynamics studies in rings,
PASS=0, closed orbit computation and correction will include the effect of
the kick; however, matrix-based computations by default will not (set
change this). If
PASS>0, then closed orbit computation and correction do not include
the kick, which is probably what is desired in beam dynamics studies in rings.
