“…The CW beam was generated by the hot cathode with a grid pulse. In the 1990s, a high-power thermionic electron gun synchronized to a 1 GHz RF was developed [10]. This development provided the basis for high-power, high-repetition thermionic electron guns.…”

In recent years, there has been an increasing demand for high-intensity beams in the field of electron beam irradiation. This includes mass production of nuclear medicine examinations using 99Mo and high-efficiency production through material modification via material irradiation. Although superconducting cavities can achieve high-current beam acceleration, a compact accelerator is desirable for general-purpose irradiation beams. In this paper, we designed a practical 10 MeV, 50 mA high-current beam irradiator using a new Nb3Sn superconducting cavity.

In this paper, the design and simulation of an electron injector based on a thermionic RF modulated electron gun for particle accelerator applications is presented. The electron gun is based on a gridded thermionic cathode with the geometry based on a Pierce-type configuration. Both theory and numerical simulation were used to explore the relationship between the bunch length and charge. The reasons for the pulse widening were also analyzed. The beam dynamics simulations showed that a minimum pulse length of 106 ps could be achieved with a bunch charge of 33 pC when the driving RF frequency was 1.5 GHz. The average transverse emittance was about 17 mm⸱mrad from the particle-in-cell simulations. Operating at a higher RF frequency did not significantly reduce the micro-pulse length.
