Martin COLLET
Scientist
I obtained my PhD in Physics from Université Paris-Saclay in 2017, where my research focused on the design and study of microwave devices for telecommunications applications. I then joined Thales SIX GTS as an RF engineer, working on the design, integration, and qualification of electronic boards for critical systems. Since July 2021, I have been a research engineer at CEA DAM Île-de-France, within the team responsible for the ELSA radio-frequency linear electron accelerator. My role is to develop, modernize, and maintain the accelerator’s RF systems, which are central to the operation of the facility. This responsibility has allowed me to build in-depth expertise on the various subsystems while ensuring the continuity and reliability of beam delivery. I am leading several major modernization projects, including the replacement of the 144 MHz photoinjector tube amplifier with a transistor-based technology, the optimization of the 1.3 GHz RF system in collaboration with other CEA departments, and the development of a new frequency control system for the 144 MHz and 433 MHz RF cavities. In parallel, I actively support numerous experimental campaigns carried out on ELSA for various CEA laboratories, ensuring the operation of the electron beam and measurement systems, from initial setup to end-of-day operations.
