| Description | 積層させた薄片状タンタル酸リチウムまたはニオブ酸リチウム単結晶とセラミックヒーターを用いた小型高電場発生デバイスを製作し，これまでの検討より高温領域である室温から 650 K までの間でX 線発生実験を行った．473 K から650 K まで10–4 Pa 下で加熱すると最高28 keV のX 線が発生した．積層させた焦電結晶の側面では温度変化に伴い局所的な放電が繰り返し起こった．焦電結晶の形状と放電発生について議論した．

| Description Alternative | 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.
