本文比较了在镍衬底上采用不同工艺制备的多碱发射体材料,发现其碱金属的相对比例有很大的不同。据此作者提出侧窗光电倍增管的高增益性能在相当大程度上取决于钾、钠、铯组分的恰当比例,而良性配合可由多种途径达到。 This article compares polybase emitter materials prepared on different nickel substrates using different processes and found that the relative proportions of alkali metals are quite different. Accordingly, the authors propose that the high gain performance of the side-window photomultiplier tubes depends to a large extent on the appropriate proportions of potassium, sodium and cesium components, and that benign complexes can be achieved in a number of ways.
