BPM

BPM element

Represents a BPM element Calibration errors are deviation variables (not specified on initialization) Transforms input to BPM or to beam frame (initialization flag) To represent the full transformation (beam-BPM-beam), two elements with the same name can be used (or change the direction switch)

class model.library.bpm.BPM(name: str, direction: Literal['forward', 'inverse'] = 'forward', dp: float = 0.0, output: bool = False, matrix: bool = False)
