    摘要: A dynode (8) constituting an electron multiplier or a photomultiplier is provided with eight rows of channels (15) each defined by an outer frame (16) and a partitioning part (17) of the dynode (8). In each channel (15), a plurality of electron multiplying holes (14) are arranged. In specified positions of the outer frame (16) and the partitioning part (17) of the dynode (8), glass receiving parts (21) wider than the outer frame (16) and the partitioning part (17) are provided integrally with the dynode (8). Glass parts (22) are bonded to all the glass receiving parts (21). The glass parts (22) are bonded by applying glass to the glass receiving parts (21) and hardening the glass and each have a generally dome-like convex shape. Each dynode (8) is formed after the dome-like glass part (22) is bonded to the glass receiving part (21).

    摘要: An image intensifier and electron multiplier therefor is disclosed. Photons of an image impinge a photo-cathode that converts the photons to electrons. An electron multiplier multiplies the electrons from the photo-cathode to create an increased number of electrons. A sensor captures the increased number of electrons to produce an intensified image. The electron multiplier is an electron bombarded device (EBD) containing a semiconductor structure. The semiconductor structure has an input surface for receiving electrons and an emission surface for passing an increased number of electrons. The semiconductor structure is doped to direct the flow of electrons through the semiconductor structure to an emission area on the emission surface.

    摘要: A multi-purpose efficient charge particle detector that by switching bias voltages measures either secondary ions, or secondary electrons (SE) from a sample, or secondary electrons that originate from back scattered electrons (SE3), is described. The basic version of the detector structure and two stripped down versions enable its use for the following detection combinations: The major version is for measuring secondary ions, or secondary electrons from the sample, or secondary electrons due to back-scattered electrons that hit parts other than the sample together or without secondary electrons from the sample. Measuring secondary ions or secondary electrons from the sample (no SE3). Measuring secondary electrons from the sample and/or secondary electrons resulting from back-scattered electrons hitting objects other than the sample (no ions).

    摘要: A photomultiplier tube (1) in which electron multiplication holes (8a) are formed by etching through a stack of plate-shaped dynodes (8). In the etching process, a pattern frame (22) is disposed around a plate-shaped dynode substrate (20) to connect the pattern frame (22) to the edges (20a) of the dynode substrate (20) with bridges (23), and a number of electron multiplication holes (8a) are formed by etching using a mask which covers the dynode substrate (20). By cutting off the bridges (23) on the dynode substrate (20) side, a part of each bridge (23) slightly remains along the edge (8b) of the dynode (8). To minimize noise generation due to the remainders of the bridges, the bridges remainders (8c) of neighboring dynodes are arranged so that straight lines passing through the bridge remainders (8c) and parallel to the direction of the stack of the dynodes do not lie on each other, thereby further improving making fundamental characteristics of the photomultiplier tube.
