McXtrace: JJ_SAXS

[ Identification | Description | Input parameters | Output parameters | Links ]

The JJ_SAXS Instrument

Crude model of a laboratory SAXS-instrument mimicking the type sold by SAXSlab/JJ-Xray Systems.


  • Site: SAXSLAB
  • Author: Erik Knudsen (
  • Origin: Risø DTU.
  • Date: September 24th, 2009


This is a very sketchy model of a SAXS-system, related to the old design of JJ X-ray systems.
It has been superseeded by the SAXS_saxslab model.
Limitations include:
- Focusing only in 1 direction.
- iNo reflectivity coating is implemented.

Input parameters

Parameters in boldface are required; the others are optional.
pin2_posmdistance between 1st and 2nd pinhole in beam tube0.2
pin3_posmdistance between 2nd and 3rd pinhole in beam tube0.4
optic_Lmlength of the focusing optic0.1
sample_posmdistance from 3rd pinhole to sample0.2
detector_posmdistance from 3rd pinhole to detector2
