PMQ_Trace3D_Function#

class orbit.py_linac.overlapping_fields.PMQ_Trace3D_Function(length_param, rad_in, rad_out, cutoff_level=0.01)[source]#

The PMQ Function is a represenatation of the field of permanent quad from Trace3D documantation (p 77): https://inis.iaea.org/records/7awtr-mr708

Methods Summary

`getFuncDerivative`(z)	Returns the derivative of the getFuncValue(z)
`getFuncValue`(z)	Returns the quad's field at the distance z from the center
`getLimitsZ`()	Returns (z_min,z_max) tuple as longitudinal limits of the quad field.
`getPMQ_FuncValue`(z)	Returns the total PMQ quad field distribution
`pmq_func`(z)	This is PMQ function defined at p.
