Broad-band High-Energy Resolution Hard X-ray Spectroscopy using Transition Edge Sensors at SPring-8

Shinya Yamada, Yuto Ichinohe, Hideyuki Tatsuno +40

We have succeeded in operating a transition-edge sensor (TES) spectrometer and evaluating its performance at the SPring-8 synchrotron X-ray light source. The TES spectrometer consi…

The energy dependence of cluster size and its physical processes in the proton measurement with TimePix3 silicon detector

Naoki Itoh, Hugo Allaire, Tokihiro Ikeda +7

We investigated the energy dependence of the number of triggered pixels, or cluster size, when charged particles are detected using the TimePix3 detector with a silicon sensor. We…

Testing Quantum Electrodynamics with Exotic Atoms

Nancy Paul, Guojie Bian, Toshiyuki Azuma +2

Precision study of few-electron, high- ions is a privileged field for probing high-field, bound-state quantum electrodynamics (BSQED). However, the accuracy of such tests is pla…
