The pulse pyroelectric source is equipped with an additional electron emitter in the form of a filament. In this work, we propose a three-electrode configuration of the pyroelectric accelerator with an additional grid electrode located between the pyroelectric crystal and the electron emitter. Thus, it becomes possible to control the duration of generation and the magnitude of the X-ray flux in the pulsed pyroelectric source. The prospects for development of the pulse miniature sources are discussed. ER -
