Abstract

1,271,284. Electron multipliers. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 29 July, 1969 [9 Aug., 1968], No. 37903/69. Heading H1D. An electron multiplier comprises a cylinder 45, Fig. 5A, made of or coated internally with a secondary emissive resistive material and a coaxial repeller electrode 47 made of or coated with resistive material and adapted to produce an electric field with equipotential lines extending at an acute angle of preferably between 55 and 75 degrees to the secondary emissive electrode. In the arrangement shown, a potential gradient is established along the cylinder 45, and a similar gradient lower at each point is established along the repeller electrode 47 with the aid of auxiliary potential sources 36, 37. The secondary emissive material may be magnesium oxide or potassium chloride.
