Abstract: A photomultiplier tube in which a photoelectron beam (42) is divided in N independent paths by means of an electron-optical device. The optical device includes a first cup-shaped focusing electrode (25) having a flat bottom portion of polygonal or circular shape, in which N apertures (30a), (30b) are formed, and having raised side faces (28a), (28b) which extend towards the photocathode (12), viewed in the radial directions corresponding to the elementary photomultipliers, and side faces having V-shaped recesses between these directions. The optical device is completed by a deflection electrode (35) which is brought to approximately the same potential as the photocathode and which is centrally arranged close to the bottom portion of the focusing electrode (25). The assembly is followed by a multiplier (16) of the perforated sheet-type whose focusing electrode (161) has projecting portions (41a), (41b), the multiplier being followed by N anode plates (20a), (20b).

Abstract: A reversible short circuit device in the form of a metal loop. The metal loop has a first base side which forms a first contact. Extending from the base side are second and third generally parallel sides. The second side includes a contact portion for engagement with an external object to provide an electrical connection therewith. The second and their sides are connected by a frangible fourth connection side. One of the second and third sides is subject to a recoiling force, which, when the connection side is interrupted or broken displaces the contact portion of the second side so as to reverse the short circuit. The short circuit device has particular application to photoelectric tubes to provide a means for interconnection of the tube components during manufacture, which may subsequently be reliably disconnected.
