Function to calculate transverse kick by corrugated structure [SLAC-PUB-16881]
ocelot.utils.wake_pws.wake_tables(b=500 * 1e-06, a=0.01, width=0.02, t=0.25 * 0.001, p=0.5 * 0.001, length=1, sigma=3e-05, filename=None)

Function creates two wake tables for horizontal and vertical corrugated plates

Parameters

  • b – distance from the plate in [m]

  • a – half gap between plates in [m]

  • width – width of the corrugated structure in [m]

  • t – longitudinal gap in [m]

  • p – period of corrugation in [m]

  • length – length of the corrugated structure in [m]

  • sigma – characteristic longitudinal beam size in [m]]

  • filename – save to files if filename is not None

Returns

hor_wake_table, vert_wake_table

ocelot.utils.wake_pws.wake_kick(p_array, b=500 * 1e-06, t=0.25 * 0.001, p=0.5 * 0.001)

Function to calculate transverse kick by corrugated structure [SLAC-PUB-16881]

Parameters

  • p_array – ParticleArray

  • b – distance to the dechirper wall

  • t – longitudinal gap

  • p – period

Returns

(wake, current) - wake[:, 0] - s in [m], wake[:, 1] - kick in [V] - current[:, 0] - s in [m], current[:, 1] - current in [A]
