The Template_DCM Instrument

Template for a vertically defleting DCM

Identification

• Site: Tests_optics
• Author: Erik B Knudsen
• Origin: DTU Physics
• Date: Jan '21

Description

Simple skeleton instrument showing a vertically deflecting
double crystal monochromator. To instead make it horizontally deflecting
simply add Arms before and after the crystal assembly that rotate by
90 and -90 deg. respectively around the z-axis.
The crystal is illuminated by a model point source.

Examples

(Test cases in bold)

• Test: theta=9.17 Detector: emon_dcm1_I=6.14859e-10

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
E0	keV	Central energy to be emitted by the source. 0=set from theta.	0
dE	keV	Half width to be emitted by the source	0.2
theta	deg	Rotation angle of the crystals. 0=set from E0.	9.17
