BUMPER

A time-dependent uniform-field rectangular kicker magnet with no fringe effects. The waveform is in SDDS format, with time in seconds and amplitude normalized to 1.
Parameter Name Units Type Default Description
L $M$ double 0.0 length
ANGLE $RAD$ double 0.0 kick angle
TILT $RAD$ double 0.0 rotation about longitudinal axis
B2 $1/M^2$ double 0.0 Sextupole term: By=Bo*(1+b2*x2)
TIME_OFFSET $S$ double 0.0 time offset of waveform
PERIODIC   long 0 is waveform periodic?
PHASE_REFERENCE   long 0 phase reference number (to link with other time-dependent elements)
FIRE_ON_PASS   long 0 pass number to fire on
N_KICKS   long 0 Number of kicks to use for simulation. 0 uses an exact result but ignores b2.
WAVEFORM   STRING NULL $<$filename$>$=$<$x$>$+$<$y$>$ form specification of input file giving kick factor vs time
