mbtrack2.impedance.tapers module

Module where taper elements are defined.

class StupakovRectangularTaper(frequency: ndarray[tuple[int, ...], dtype[_ScalarType_co]], gap_entrance: float, gap_exit: float, length: float, width: float, m_max: int = 100, n_points: int = 10000)

Bases: WakeField

Rectangular vertical taper WakeField element, using the low frequency approxmiation. Assume constant taper angle. Formulas from [1].

! Valid for low w

Parameters

frequency: frequency points where the impedance will be evaluated in [Hz] gap_entrance : full vertical gap at taper entrance in [m] gap_exit: full vertical gap at taper exit in [m] length: taper length in [m] width : full horizontal width of the taper in [m]

__init__(frequency: ndarray[tuple[int, ...], dtype[_ScalarType_co]], gap_entrance: float, gap_exit: float, length: float, width: float, m_max: int = 100, n_points: int = 10000)
