摘要：PURPOSE:To prevent the condary electron multiplication from being lowered, and narrow energy distribution width and electron beam diameter by forming a conductive layer on the outer wall of a tube only for the desired length of the input end direction from the output end and a layer consisting of the material with a large condary electron discharge width on the inner wall. CONSTITUTION:The tube wall 12 of the channel type condary electron multiplier 11 has the electrode 13 at the opening end over which the primary charged particles are incident and the electrode 14 at the output end. A conductive layer is formed on the outer wall of the channel type condary electron multiplier only for the desired length toward the input end from the opening and output ends. The layer 15 consisting of the materials with the large condary electron discharge ratio, for example, potassium chloride, cesium iodide or lithium floride is formed on the inner wall of the electron multiplier only for the same length as the electrode 14 toward the input end from the output end. This permits the multiplication of the condary electrons which are discharged from the output end to be prevented from being reduced and the energy distribution and electron beams to be narrowed.
