Description

Accelerator based facility for elemental analysis using nuclear and X-ray techniques with applications in e.g. medicine, biology, geology, astro-geology, material analysis, archeology. Sample sizes from cm down to micro-metres. Detection limits from 10 ppm down to sub ppm depending on element and analytical method.

Equipment and resources

3MV single-ended electrostatic accelerator with two active beam lines holding three specialized chambers for elemental analysis and material modification:
1) Macro chamber for routine PIXE elemental analysis of cm-sized samples, typically aerosol filters.
2) Total Ion Beam Analysis (TIBA) chamber combing two large solid angle position sensitive particle detectors, a gamma-ray detector and an X-ray detector for the measurement of most elements.
3) A chamber for micro-PIXE analysis using a large solid angle X-ray detector micro-scale elemental analysis.

Digital and physical collections

Digital raw data, digital evaluated data, result compilations. Data stored locally.

Services provided

Quantitative elemental analysis in a scale from micrometer level up to cm using different or combined methods of ion beam analysis. By nuclear reaction analysis: H, D, Li-7, B-11, O-18, F-19, by PIXE from Na, Mg and heavier. A beam focused down to 5 µm can be obtained scanning over the sample for elemental mapping in TIBA setup and down to 1 µm in the micro-PIXE setup.

Management of the infrastructure

Managed by Charlotta Nilsson with a small steering group.
