We have observed a deflection of relativistic electrons beam with an energy of 7 MeV in a transverse electric field, which is created by means of a pyroelectric deflector [1]. The experiment was performed on the microtron of the "Pakhra" accelerator complex in Lebedev Physical Institute. The deflection of the beam for angle of 1.43⁰ was observed on a fluorescent screen installed at a distance of 70 cm from the deflector. The transverse electric field strength generated by the pyroelectric deflector was 75 kV / cm when the crystals were heated from room temperature to 50 ⁰C. Experimental data are compared to calculations. The perspectives of creating a pyroelectric undulator are discussed.
