The `Test_Radial_div` Instrument

Test of the contributed Radial_div monitor

Identification

Site: Tests_monitors
Author: P. Willendrup
Origin: DTU
Date: 20. October 2026

Description

A small, weakly divergent beam is recorded by a PSD_monitor and by a Radial_div
monitor of the same size. With the beam divergence well within maxdiv_r and
all wavelengths within [Lmin, Lmax], both monitors record the same intensity.
Narrowing [Lmin, Lmax] makes Radial_div count only part of the beam.

Examples

(Test cases in bold)

Test: Test_Radial_div.instr Lmin=0.5 Lmax=10 Detector: PSD_I=0.000100531
Test: Test_Radial_div.instr Lmin=0.5 Lmax=10 Detector: RadDiv_I=0.000100531
Test: Test_Radial_div.instr Lmin=4 Lmax=6 Detector: RadDiv_I=2.51059e-05

Input parameters

Parameters in boldface are required; the others are optional.
