The development of LGAD technology for charged particle detection is currently experiencing significant growth and demonstrating great performance in applications such as reaction time measurement, beam monitoring and ion CT thanks to its excellent timing properties. Preliminary measurements conducted with He and C ions have shown very promising results and great potential for heavy ion applications.

This presentation will focus on the results achieved using LGAD detectors for measuring the time-of-flight of protons as well as He and C ions conducted at the MedAustron institute, and will also showcase an example of using these sensors to diagnose radiation damage in a pcCVD diamond sensor.

Keywords: Low Gain Avalanche Diode; Ion Computed Tomography; Time-of-flight
