Abstract

<p>A high temperature-type compact device for pyroelectric high electric field generation was assembled with 8 pieces of thin-type LiTaO3 or LiNbO3 single crystals (10 × 10 × 0.5 mm) stacked and a ceramic heater. Pyroelectricity-induced X-ray emission behavior from the crystals was investigated as a function of ambient temperature in the range 300 through 650 K. End-point energy of continuous X-ray was 28 keV upon heating of stacked thin LiTaO3 crystals from 473 to 650 K. Discharge behaviors at the side of stacked pyroelectric crystals accompanied with X-ray emission were also discussed.</p>
