CryoGenX - A High-resolution Spectrometer for Advanced Nuclide Analysis — •Kevin Phelan^1,4, Andreas Fleischmann¹, Matthias Bühler², Theo Hertrich², and Michael Huber³ — ¹Kirchhoff Institut für Physik, Universität Heidelberg — ²Low Temperature Solutions UG — ³PAYR Engineering GmbH — ⁴Kaon GmbH

The EuroStars CryoGenX project is developing a complete, cryogenic detector system for x- and gamma-rays up to 200 keV. Target markets are non-destructive analysis for nuclear forensics, materials analysis and nuclear metrology for medical applications.

Cryogenic detectors can resolve energies where nuclear forensics communities have difficulty identifying the content and origin of nuclear active materials. A commercially available system could prove to be very useful for nuclear metrology, non-proliferation inspection and medical radiology.

There are currently two approaches for quantifying radioactive samples. Mass spectrometry with wet-chemistry is accurate but costly and complicated. Semiconductor detectors are easy but inaccurate. CryoGenX combines the advantages of both, ensuring fast, accurate results without destroying the samples, and with no radioactive waste.

The cryogenics is based on a very small ADR. The detectors are based on the MMC / MPT concept and will be tailored for a combination of energies and working temperatures. The SQUID read-out, cryostat automation and extensive data analysis including spectral information, peak identification and high-level analytics and file handling are all highly integrated.
