    Abstract: An ion feedback electron multiplier has an envelope containing an ionizable gas. Within the envelope is a chain of multiplier dynodes divided into two planar groups spaced from and parallel to one another. At one end of the multiplier chain is an electron source capable of emitting electrons upon ion bombardment. An electron lens which is between the multiplier chain and the electron source, focuses the electrons from the source onto one of the dynodes of the multiplier.

    Abstract: A chain of planar dynodes is divided into two groups which are spaced from and substantially parallel to each other. A cathode which is capable of emitting electrons upon ion bombardment is at one end of the dynode chain. An envelope encloses the dynodes and the cathode. Also enclosed by the envelope are a plurality of shields. Each shield is located so as to prevent gas ions, present within the envelope, from striking the dynodes, while allowing the ions to strike the cathode.

    Abstract translation: 平面倍增电极的链条被分成与彼此间隔开并且基本上彼此平行的两组。 能够在离子轰击时发射电子的阴极位于倍增极链的一端。 信封包围倍增极和阴极。 也由封套包围的是多个屏蔽。 每个护罩的位置是为了防止存在于外壳内的气体离子撞击倍增极,同时允许离子撞击阴极。
