The Chopper_simple Component

Written by; Erik Knudsen Ideal chopper

Identification

Description

Ideal model of a chopper situated at Z=0. If a photon arrives at the chopper plane
at a time of t = [t0 +-n*T: t0 +-n*T +tau], where T is the period of the chopper, t0 the initial delay
and tau the opening time of the chopper, it is left untouched - otherwise it is ABSORBed. 
If on a continous source the isfirst parameter may be used. In this case the photon time is _defined_
by the chopper.
Limitations: this component does not take chopper geometry into account.

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
t0 s initial delay of the opening time 0
T s period of the chopper 1
tau s opening time of the chopper 0.1
xwidth m height of the chopper opening 0.1
yheight m width of the chopeper opening 0.1
isfirst 0
