Abstract

A new type deflector of a charged particle beam based on pyroelectric crystals is proposed and demonstrated experimentally. The transverse electric field arises in the gap between two pyroelectric crystals in vacuum because of the pyroelectric effect appearing when a temperature gradient is applied to both crystals. In a proof-of-principle experiment, we demonstrated deflection of a low-energy electron beam. The application of pyroelectric deflectors as bending elements in the pyroelectric undulator for production of the undulator radiation is proposed.
