Parameters of electron beam generated by RF gun with ferroelectric cathode

Autor: Khodak, I.V., Kushnir, V.A., Romas’ko, V.P., Zakutin, V.V.

RF guns with thermoemission and photoemission cathodes generate an electron beam pulse current and current pulse duration of 10⁻¹…10³ A and 10⁻⁶…10⁻¹² s, respectively. It is proposed to apply a ferroelectric cathode in RF gun. S-band

Emittance measurement of electron beam of RF gun with plasma ferroelectric cathode

Autor: Khodak, I.V., Kushnir, V.A.

An RF gun with a plasma ferroelectric cathode can generate intense electron beams with peak current in a bunch up to 10² A. The space charge forces of the beam increase errors of the beam emittance measurement using a ‘quadrupole’ technique. The

On transversal instability of beam in powerful S-band linear electron accelerators

Autor: Aizatsky, M.I., Kramarenko, E.U., Khodak, I.V., Kushnir, V.A., Mytrochenko, V.V., Perezhogin, S.A.

High pulse current of electrons in a linear resonance accelerator assists the increase of overall efficiency of the facility. At the same time, there is a danger of development of transversal instability of a beam (BBU), especially in linacs consisti

High-current hollow beam dynamics in RF electron guns

Autor: Khodak, I.V., Kushnir, V.A., Mitrochenko, V.V.

RF electron guns with a metal-dielectric cathode are able to generate intense beams with nanosecond current pulse duration. The plasma developed during the dielectric surface flashover in vacuum is the source of particles of the cathode. Results of t
