pyccapt.calibration.mc.mc_tools module

pyccapt.calibration.mc.mc_tools.tof2mc(t: int, t0: int, V: float, xDet: int, yDet: int, flightPathLength: int, V_pulse: float, mode: str = 'voltage') → None

Calculate m/c based on idealized geometry and electrostatics using the formula: m/c = 2eα(V + βV_pulse)(t/L)^2

Parameters:

• t – Time (unit: ns)

• t0 – Initial time (unit: ns)

• V – Voltage (unit: volts)

• V_pulse – Voltage pulse (unit: volts)

• xDet – Distance along the x-axis (unit: mm)

• yDet – Distance along the y-axis (unit: mm)

• flightPathLength – Length of the flight path (unit: mm)

• mode – Type of mode (‘voltage’ or ‘laser’).

Returns:

Mass-to-charge ratio (unit: Dalton)

Return type:

mc
