The Airp_scannerII Instrument

Example instrument to display how to use the absorption multiobject component

Identification

• Site: DTU
• Author: E. B. Knudsen (erkn@fysik.dtu.dk)
• Origin: DTU Physics
• Date: Jan '21

Description

This instrument simply has a lab source, a few monitors and a multi-off object scene
by means of the Abs_objects component. By supliying a control file and a set of
off/ply-files a scene is put together which may be used for tomography style
simulations. The default input file contains a single object: a mechanical socket.

Examples

(Test cases in bold)

• Test: Airport_scannerII.instr -n1e5 Ncount=1e4 posX=-0.25 posY=-0.3 Detector: psd2_I=0.000629398

Input parameters

Parameters in boldface are required; the others are optional.
