Effect of oxygen and nanoparticles on human skin and colon cells exposed to synchrotron-based X-ray FLASH beams

Most cancer patients will be treated by radiotherapy, and recent findings suggest that delivering radiation at `FLASH' ultra-high dose rates reduces damage to healthy tissues while still damaging the tumour. This project experimentally validates the reduced healthy tissue damage of FLASH radiotherapy on cells using synchrotron-based beams, which will support future clinical trials and ultimately leading to its application in cancer treatment.

For adaptive X-ray optics on high-performance beamline optical systems, we describe an approach to mirror figure and slope control using patterned, shaped electrodes to control the local curvature on a lithium niobate substrate from a single applied voltage. Longitudinally continuous electrode patterns achieve target shapes without discontinuities, and compound electrodes enable multiple target shapes to be achieved on a single substrate.

Gepta-EX: a multi-channel germanium detector for X-ray absorption fine structure

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.

Full-field X-ray fluorescence imaging using a Fresnel zone plate as a coded aperture: optimized reconstruction algorithm and first trial of hyperspectral XANES mapping

The full-field X-ray fluorescence imaging method, where a Fresnel zone plate is employed as a coded aperture, was tested for the first time at a beamline, and its corresponding reconstruction code was optimized. It was also employed to perform, also for the first time using full-field and fluorescence modes, hyperspectral XANES mapping.
