本文描述了一种用于超高真空测量的改进型分离规的设计和特性。栅网的开端结构可防止直接打到离子收集极的ｘ射线，除了那些各电极上反射的少数间接的ｘ射线以外。在相当于残余气体１毫安电子流时，灵敏度系数约为８．３×１０－２Ｐａ－１（１１托－１）。可实现的压强测量范围在 １×１０－６到９×１０－１０Ｐａ（１× １０－８到 ７× １０－ １２托）。业已证实，这种规管的ｘ射线极限低于裸体 Ｂ－Ａ规。文章还叙述了通过把帽电极装在栅网顶部的简化方法，可用于高真空压强测量的改进型规管设计。
This article describes the design and characteristics of an improved splitter gauge for ultra-high vacuum measurements. The grid's beginning structure prevents x-rays from directly striking the ion collector, except for the few indirect x-rays that reflect on each electrode. The sensitivity factor is about 8.3 x 10-2 Pa-1 (11 torr-1) at 1 milliampere electron flow equivalent to the residual gas. The achievable pressure measurement ranges from 1 × 10-6 to 9 × 10-10 Pa (1 × 10-8 to 7 × 10-12 Torr). It has been demonstrated that this regulatory x-ray limit is lower than the nude B-A gauge. The article also describes an improved regulatory design that can be used for high vacuum pressure measurements by a simplified method of mounting the cap electrode on top of the grid.
