我们报告了 LiTaO3 热释电晶体的加速潜力显着增加。使用单个直径 2.5 厘米、长 2.5 厘米的 z 切晶体，没有电场增强纳米尖端，当晶体暴露于 5 毫托氘气时，我们在冷却阶段产生了最大能量在 300 至 310 keV 之间的正离子束。这些值比之前使用单个热释电晶体获得的值大约大 2 倍。
We report on a substantial increase in the acceleration potential achieved with a LiTaO3 pyroelectric crystal. With a single 2.5 cm diameter and 2.5 cm long z-cut crystal without electric field-enhancing nanotip we produced positive ion beams with maximal energies between 300 and 310 keV during the cooling phase when the crystal was exposed to 5 mTorr of deuterium gas. These values are about a factor of 2 larger than previously obtained with single pyroelectric crystals.
