Quantitative framework for photoemissive materials: From bialkali-antimonide synthesis to performance in superconducting RF electron injectors

Jonas Dube, C. Wang, E. J. Brookes, A. Neumann et autres

Photoemissive materials are central to a wide range of technologies, including ultrafast imaging, low-light detection, and accelerator-based light sources, where they determine the fundamental performance limits of these instruments. Despite their importance, establishing quantitative links between material synthesis, electronic structure, intrinsic photoemission …

Commissioning of ThomX Compton source subsystems and demonstration of 10 10 x-rays/s

Muath Alkadi, M.A. Alves, Manar Amer, Loïc Amoudry et autres

ThomX is a compact x-ray source based on Compton scattering, installed at IJCLab (Laboratoire de physique des 2 infinis-Irène Joliot-Curie) in Orsay. The machine uses a small electron storage ring and an intense laser pulse stored in a high-finesse optical cavity. This …

Injection Feedback for a Storage Ring

Alexandre Moutardier, Nicolas Delerue, C. Bruni, I. Chaikovska et autres

We report on an injection feedback scheme for the ThomX storage ring project. ThomX is a 50-MeV-electron accelerator prototype which will use Compton backscattering in a storage ring to generate a high flux of hard X-rays. Given the slow beam damping (in …

Transverse Impedance Coaxial Wire Measurement in an Extended Frequency Range

Ezgi Ergenlik, C. Bruni, Alexis Gamelin, Damien Le Guidec et autres

The low energy accelerators are tend to have some instabilities especially the beam coupling impedances which comes from the interaction between the beam and accelerator components. As long as the longitudinal impedance are important, transverse impedance determination is crucial for determine the …
