The prototype DynamiX camera system – a high‐frame‐rate high‐dynamic‐range hard X‐ray integrating detector for fourth‐generation synchrotrons

Journal of Synchrotron Radiation, EarlyView.
This paper presents the first results from the DynamiX X‐ray imaging detector developed by the UK's Science and Technology Facilities Council for a new generation of photon light sources. Operating at a continuous frame rate of 534 kHz and with a per‐pixel per‐frame dynamic range of roughly five orders of magnitude, this work is the first step in ...

Performance-limiting Defects in CdZnTe Detectors [PDF]

2006 IEEE Nuclear Science Symposium Conference Record, 2006
We studied the effects of small, < 20 mum, Te inclusions on the energy resolution of CdZnTe gamma-ray detectors using a highly collimated X-ray beam and gamma-rays, and modeled them via a simplified geometrical approach. Previous reports demonstrated that Te inclusions of about a few microns in diameter degraded the charge-transport properties and ...

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Shadow‐Free Back‐Contact Perovskite Thin‐Film Detectors for Direct Extreme‐Ultraviolet and Soft X‐Ray Sensing

Advanced Materials Interfaces, Volume 13, Issue 14, 21 July 2026.
A triple‐cation perovskite detector with a quasi‐interdigitated back‐contact architecture enables highly sensitive and linear EUV/soft x‐ray detection by minimizing electrode shadowing and enhancing charge extraction. Efficient interfacial carrier collection and rapid temporal response highlight the potential of back‐contact‐engineered perovskites for ...
