dc.description.abstract© 2021, Pleiades Publishing, Ltd.Abstract: Emission of short electron bunches with high charge in RF guns is considered. The emission mechanism in the case of picosecond laser pulses and the presence of a strong electric field at the cathode is quite different from the traditional one limited by the space charge of emitted particles. In this case, it is necessary to take into account the influence of positive charge dynamically formed on the cathode surface related to the difference of velocities of photoelectrons leaving the semiconductor film of the photocathode and velocities of electrons entering the emission region. The comparison of the numerical results and experimental data obtained at the facility for testing photoinjectors at PITZ (DESY, Zeuthen, Germany) demonstrated good agreement.
