| Abstract |
Single crystals of lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) can be used to accelerate electrons and positive ions to energies of the order of 100 keV and generate X-rays and fast neutrons, as well as to control beams of charged particles. However, this way of particles acceleration and generation is not widely used yet due to an unstable particle flux caused by electric breakdowns or crystal impurities leading to temporal discontinuity of pyroelectric current. A sinusoidal mode of the temperature change demonstrated stable oscillations of the pyroelectric current on the polar surface with typical frequency being of the order of 1-50 mHz and the amplitude being about 1-10 nA for samples with area of several cm². In vacuum it leads to generation of high electric field, which oscillates with the same frequency. Estimated amplitude of electric field is order of 105 V/cm. The possibilities of using such mode of temperature change to obtain a quasi-stable X-ray and electron source are considered. The fundamental properties and further prospects for the application of thermoelectric oscillations are also discussed.
