Pyroelectric deflector of relativistic electron beam

Deflection of a relativistic electron beam by means of the pyroelectric deflector is demonstrated experimentally for the first time. The operating principle of the pyroelectric deflector is based on the generation of a strong transverse electric field in a vacuum in the gap between a pair of pyroelectric crystals due to the pyroelectric effect. The experiments on observation of deflection of 7 MeV electron beam for 26 mrad in the transverse electric field with a strength of about 100 kV/cm arising at a variation of the temperature of a pair of pyroelectric crystals in vacuum are described. The possibility for application of the installed sequentially pyroelectric deflectors in pyroelectric undulator for production of undulator radiation by relativistic electron beam without any external high voltage power supply is discussed.

Automated summary

This study experimentally demonstrates for the first time the deflection of a relativistic electron beam using a pyroelectric deflector. The operating principle of the deflector relies on the generation of a strong transverse electric field in a vacuum using the pyroelectric effect. The experiments show that a 7 MeV electron beam can be deflected by 26 mrad in a transverse electric field with a strength of about 100 kV/cm, achieved by varying the temperature of a pair of pyroelectric crystals. The study also discusses the potential application of sequentially installed pyroelectric deflectors in pyroelectric undulators for generating undulator radiation by a relativistic electron beam without the need for an external high voltage power supply.
