Abstract: A monitoring device transparent to ionizing radiation, designed to measure the orientation, intensity and uniformity of an incident beam, comprises a cylindrical housing forming at least one ionization chamber with one or more ion-collecting electrodes transverse to the housing axis, each electrode being subdivided into a plurality of mutually insulated conductive elements connected to respective amplifiers. The elements of at least one electrode include one or more outer elements surrounding or bracketing one or more inner elements to measure the radiation in a central zone and a peripheral zone. The outputs of the respective amplifiers are additively and subtractively combined in an evaluation circuit.

Abstract: An image converter is used to make visible images produced by gamma rays or similar penetrating rays like X-rays, etc., by transforming the distribution of ray density contained in a bundle of rays carrying the image which is to be made visible, by means of a cathode and an anode spaced from the cathode. The space between the electrodes contains a gas and the electrodes are subjected to a voltage which produces electrical discharges during ray penetration at corresponding locations depending upon the rays. The cathode as well as the anode consist of a plurality of parts having large surfaces which extend at least approximately perpendicularly to the ray incoming surface of the converter, so that the electric field extends parallel to this surface. The invention is particularly characterized in that the gas is under pressure in the range of 10 at., that the applied voltage makes certain the operation in the proportional range and that parts of the anode and of the cathode are combined in rows. Rows of the cathode elements and those of the anode extend at an angle to each other, the rows being connected electrically with a device for forming an electronic intensity center which produces representable local signals for orientation of the discharge bundle striking the anode.

Abstract: A long life gas-filled proportional counter radiation detector is provided having a shielded gas reservoir interconnected with the prime detection chamber. The gas fill within the detection chamber is exposed to radiation but the reservoir gas is shielded to thereby minimize dissociation and absorption of the gas upon the chamber wall.

Abstract: A boron nitride core is coated with polytetrafluorethylene (Teflon) or a similar fluorocarbon resin to form a composite gassealant insulator for use at temperatures up to about 370* C., highly resistant to mechanical deformation or chemical attack. A flow proportional counter incorporating the insulator construction is employed as a detector in gas chromatography.

Abstract: A two-dimensional position-sensitive detector has been provided to measure the coordinates of the location and the energy loss of charged particles and ionizing radiation. The device comprises an ordered array of high resistance collector wires strung in parallel. Adjacent wires are interconnected at both ends by a series of resistors so as to form a four output terminal network. A comparison of the rise times of the output pulses from these four terminals gives the coordinates of an ionizing event within the sensitive area of the detector. The amplitude of the sum of the four output pulses gives the energy loss of the event in the detector gas.
