The TOF_PSDmonitor_toQ Component

Position-sensitive, linear Q monitor.

Identification

Description

One-dimensional Q-monitor. Calculates Q from "measured" time-of-flight,
i.e. not from particle velocity parameters.

Adapted from Kim Lefmann's TOF_cylPSDmonitor and PSD_monitors
An n pixel Q-monitor based on measured Time of Flight detection.
This component may also be used as a beam
detector.

Example: TOF_PSDmonitor_toQ(xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
ny=90, nqbin=100, TOFmin=0.0, TOFmax=20000.0, filename="Output.psd")
