Transverse beam emittance measurement of a high current DC electron gun: Simulation and experimental approaches [PDF]
AIP AdvancesHigh-current DC electron guns play a vital role in high-power electromagnetic sources. Accurate determination of essential parameters, such as transverse emittance, is important because this parameter affects the quality of the output radiation.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Gigahertz repetition rate thermionic electron gun concept
Physical Review Accelerators and Beams, 2019 We present a novel concept for the generation of gigahertz repetition rate high brightness electron bunches. A custom design 100 kV thermionic gun provides a continuous electron beam, with the current determined by the filament size and temperature.

Low-emittance radio-frequency electron gun using a gridded thermionic cathode
Physical Review Accelerators and Beams, 2020 We developed an electron gun system capable of delivering high brightness beams to drive soft x-ray free-electron lasers (SXFEL). We modified the conventional radio-frequency (rf) gun concept by using a 50-kV gun with a gridded thermionic cathode ...

Ultrashort electron bunch generation by an energy chirping cell attached rf gun
Physical Review Special Topics. Accelerators and Beams, 2014 We present a new design for a rf electron gun to be used in ultrashort (∼1 ps) electron bunch generation. Using both simulation and measurement we evaluated the principle of this new type rf gun and were able to confirm an ultrashort bunch generation ...
