53. Keynote: High-Z requirements and developments with Timepix4

David Pennicard (DESY)

Timepix4 is a versatile readout chip developed by the Medipix4 collaboration led by CERN. It can operate both in a photon-counting mode, and in an event-driven mode which provides timestamping and energy information from each hit. We present on potential applications combining Timepix4's distinctive capabilities with high-Z sensors, the resulting sensor requirements, and characterisation results.

54. In-laboratory protocol for the quantitative assessment of the time-dependent response of detectors equipped with high-Z sensors under high-energy X-ray irradiation

SPring-8 is a large-scale 3rd-generation synchrotron facility, exploiting several high-energy beamlines up to 115 keV. Direct photon-counting detectors, equipped with Cadmium Telluride sensors, are widely used in this context. However, some limitations have been identified during beamline tests, such as a non-uniform time-dependent response during irradiation and a persistent signal after...

55. Development of Multi-Energy Hard X-ray Cameras for Thermal and Non-Thermal Plasmas

Luis F. Delgado-Aparicio (Princeton Plasma Physics Laboratory (PPPL))

Soft and hard x-ray diagnostics are foundational tools in high-temperature plasma and fusion research, enabling measurements of magnetohydrodynamic (MHD) stability, energy confinement, impurity transport, runaway electron dynamics, radiated power, plasma–wall interactions, and disruptions. To significantly expand diagnostic capability, a novel multi-energy hard x-ray camera has been developed...
