本文介绍一种空腔谐振器,可用作电子速度过滤装置。这种装置可以分析、计算加速电压离散谐振值。因此,该仪器可以用来建立不确定度很小的高压定标。实验研究表明,实验值与理论值的一致性很好。电子经过空腔谐振器所产生的五个电流峰值,在40至100KV电压范围内可以进行检测。这五个值表示能计算出加速电压的电子速度过滤器的平衡条件。这些离散电压值的相隔距离是不相等的,所以测量结果是单值性的。为了大大减少不确定度,有必要进一步研究和观察。目的是要研制出一种采用超导铌谐振腔的测量仪器。使用这种量仪,能实现高达100KV的绝对直流电压的定标,其相对不确定度优于±10~(-5)。
This article describes a cavity resonator that can be used as an electronic velocity filter. This device can analyze and calculate accelerating voltage discrete resonance values. Therefore, the instrument can be used to establish high-pressure calibration with little uncertainty. Experimental studies show that the experimental values and theoretical values of good consistency. The electrons pass the five current peaks generated by the cavity resonator and can be detected over a voltage range of 40 to 100KV. These five values indicate the equilibrium conditions for the electronic speed filter at which the accelerating voltage can be calculated. The distance between these discrete voltage values is unequal, so the measurement is unambiguous. In order to greatly reduce the uncertainty, it is necessary to further study and observation. The purpose is to develop a measuring instrument using superconducting niobium resonator. The use of this meter, can achieve up to 100KV absolute DC voltage scaling, the relative uncertainty is better than ± 10 ~ (-5).
