Open for Collaboration

Short Description

The research infrastructure can be divided into two areas.

1. Luminescence measurement laboratory for measuring optically or thermally stimulated luminescence signals (OSL/TL):
For this purpose, a Lexsyg Smart Luminescence Meter from Freiberg Instruments is available, which is used for routine measurement of OSL and TL signals.

2. Preparation laboratory for physical and chemical reparation of the measurement samples:
In the red-dimmed dark laboratory, the light-sensitive samples are routinely prepared and prepared for luminescence measurement.
•Table drill rig with diamond-studded hollow drill • Precision cutting cutter with diamond-set cutting blade
• RF-compatible filter extractor
• Other laboratory equipment for physical and chemical sample preparation

Contact Person

Prof. Dr. Andreas Lang

Research Services

• OSL and TL measurement (e.g. age determination of sediments, rocks and artifacts, luminescence characterization of various materials for scientific questions (dosimetry)
• Physical sample preparation: drill core drawing by means of diamond-encrusted hollow drill, cutting by means of diamond-studded precision cutting device, sieving and gravity separation
• Chemical sample preparation: Cleaning and etching of samples, incl. hydrofluoric acid etching of quartz samples
