Generation of Ultrashort Electromagnetic Radiation Pulses with a Repetition Rate of ~100 MHz by a Vacuum Photoemission Element with an Antimony Cesium Photocathode

摘要

We studied the generation of ultrashort electromagnetic radiation pulses with the maximal repetition rate by a vacuum photoemission element with an antimony cesium photocathode. Photoelectrons are emitted as a result of supplying four nanosecond initiating laser radiation pulses with a wavelength of 527 nm and an interval from 3.65 to 6.7 ns between the pulses. The voltage between the anode and the photocathode (from 5 to 60 kV) is measured in experiments.
