在5- 50 Pa压力下测量了LiTaO_3单晶产生的X射线能谱。能谱分析表明，在10- 25 Pa压力范围内，X射线量随压力的降低呈指数增长，谱的端点能量随压力的降低呈线性增长。用0.5mm厚的LiTaO_3单晶在10 Pa的压力下获得了约22 keV的最大端点能量。假设钽酸锂单晶形成平行板电容器，估计本实验装置产生的最大能量。估计的能量与获得的能量合理一致。在低压下的击穿电位的端点能量的压力依赖性进行了讨论。
The energy spectra of X-rays produced by an LiTaO3single crystal have been measured at pressures of 5–50Pa. The energy spectra showed that the amount of X-rays increased exponentially and the endpoint energy of the spectra increased linearly with the decrease of pressure at pressures of 10–25Pa. A maximum endpoint energy of about 22keV was obtained using an LiTaO3single crystal with 0.5mm thickness at the pressure of 10Pa. The maximum energy produced by the present experimental setup was estimated assuming that the LiTaO3single crystal forms a parallel-plate capacitor. The estimated energy reasonably agreed with the energy obtained. The pressure dependence of the endpoint energy was discussed in relation to the breakdown potential at low pressures.
