This work focuses on optimizing the properties of photon counting imaging detectors of Timepix family with Silicon, CdTe and GaAs sensors.
Go to contribution page
The optimization addresses two distinct goals:
a) Achieving the best energy resolution for specific target applications such as X-ray diffraction, X-ray fluorescence imaging or absorption K-edge imaging. The energy resolution of 130 eV (Gaussian fit... -

Resonant Inelastic X-ray Scattering (RIXS) is a powerful spectroscopic technique that can probe complex electronic-structural information. Due to the wealth of possible science cases (ranging from quantum-correlated materials to photochemistry and catalysis), RIXS spectrometers have become integral parts of the scientific landscape at most synchrotron facilities and X-ray Free Electron Lasers...

Spectral and phase contrast X-ray imaging techniques have recently emerged as fundamental tools for the improvement of image quality. X-ray spectral imaging (XSI) involves the acquisition of X-ray images at multiple energies, exploiting the energy-dependent nature of X-ray attenuation to provide material composition information. This technique offers an optimal solution for visualizing and...

The High Luminosity LHC upgrade mandates a comprehensive overhaul of the CMS Drift Tubes (DT) electronics due to trigger rates surpassing current capabilities. By leveraging advancements in optical and bandwidth technologies, this upgrade presents an opportunity to redefine the architecture of DT electronics. On-detector functions undergo streamlining to facilitate the relocation of data...
