Novel diaphragm based Stirling cryocooler [PDF]

AIP Conference Proceedings, 2012
Industrial Research Ltd has developed a unique diaphragm-based pressure wave generator technology for employment in pulse tube and Stirling cryocoolers. The system uses a pair of metal diaphragms to separate the clean cryocooler gas circuit from a conventionally lubricated mechanical driver, thus producing a clean pressure wave with a long-life drive ...

Gepta-EX: a multi-channel germanium detector for X-ray absorption fine structure. [PDF]

J Synchrotron Radiat
Gepta‐EX is a compact seven‐channel high‐purity germanium detector designed to deliver high‐resolution fluorescence X‐ray absorption fine‐structure measurements at photon energies where silicon detectors become effectively transparent. It provides excellent energy resolution across a broad energy range, avoids silicon escape‐peak artifacts, and offers ...

Gaia: segmented germanium detector for high-energy X-ray fluorescence and spectroscopic imaging. [PDF]

J Synchrotron Radiat
We present Gaia, a cryogenically cooled monolithic array of 96 high‐purity germanium pixel detectors integrated with a custom low‐noise application‐specific integrated circuit and a field‐programmable gate array‐based data acquisition system. The system achieves an average energy resolution of 711 eV at 122 keV and 253 eV at 5.89 keV, and serves as the

A Proposal for a Low‐Frequency Axion Search in the 1–2 μ$\umu$ eV Range and Below with the BabyIAXO Magnet

Annalen der Physik, Volume 535, Issue 12, December 2023., 2023
This article describes the implementation of low‐frequency axion haloscope setups inside the future BabyIAXO magnet. The RADES proposal has a potential sensitivity to the axion‐photon coupling down to values corresponding to the KSVZ model, in the mass range between 1 and 2 μ$\umu$eV.
