Abstract: A multiple section photomultiplier tube (10) constructed as a matrix of several independent tubes (14) in one envelope (12). The photocathode (28) to dynode (31-38) spacings are isolated by a separator configuration (20) built with walls which interlock in cooperating slots, and each photocathode operates with its own independent dynode cage (26). The separation configuration (20) are buit-up of a shield structure which is composed of sheets and constitute an array of single chambers. One dynode (35) in each cage (26) is maintained electrically independent, and its connection is brought out of the envelope independently. This permits independent adjustment of the gain for each of the tube's multiple sections (14), so they can be adjusted to the same response for a standard radiation signal in an area. The entire tube can then be used to monitor a large area for radiation, and will yield the same response over its entire cathode area.

Abstract: A multiple section photomultiplier tube. The tube is constructed essentially as a matrix of several independent tubes in one envelope. The photocathode (12,14,16,18) of each individual section of the tube is formed into an independent surface, and the photocathode to dynode spacings are isolated by a configuration built with separator electrodes which connect to photocathode boundary dividers formed in the faceplate. The boundary dividers also isolate the independent photocathode regions. The boundary dividers can be either slots (20,22) into which the separator electrodes fit or ribs with which the separator electrodes are engaged.

Abstract translation: 一个多段光电倍增管（10），其被构造为一个封套（12）中几个独立管（14）的矩阵。 光电阴极（28）到倍增极（31-38）间隔通过隔离构造（20）隔离，所述隔板构造（20）用与在协作槽中互锁的壁互补，并且每个光电阴极利用其自己的独立倍增极保持架（26）进行操作。 每个保持架（26）中的一个倍增极（35）保持电气独立，并且其连接被独立地从信封中取出。 这允许对管的多个部分（14）中的每个部分的增益进行独立调整，因此它们可以被调整为与标准辐射信号相同的响应。 然后，整个管可用于监测大面积的辐射，并且将在整个阴极区域产生相同的响应。
