Abstract: A device for forming images of ionizing particles through single-dimensional electrophoresis provided with a multi-wire proportional chamber. The chamber filled with a gas is of asymmetric structure and is formed successively by an entry window for the particles, taken to a negative potential, a multi-wire anode electrode, taken to a potential positive with respect to a reference potential, and a cathode electrode which is placed in the vicinity of the anode electrode. The cathode electrode, which is taken to the reference potential, is formed by a network of parallel electrically conducting strips. Detection of the position of impact of the ionizing particle along the pitch of the network is performed by induction of a delayed electric pulse caused by an avalanche of the ionization electrons issuing from the ionizing particle in the region of the strip situated in line with the impact by the particle in the chamber, the reference time being that of the ionization electrons close to the wires.

Abstract: A proportional-type detector for the detection of low levels of radioactivity, such as alpha and beta particles generated by radioactive materials. In the preferred embodiment, this detector has a pancake-shaped cavity with a disk-shaped base and a cylindrical wall, with at least one anode member traversing the cavity. This anode member is maintained at an elevated potential so as to multiply and collect electrons formed within a counting gas within the cavity as a result of interaction between the radioactivity and a counter gas cavity. A perforated grid member, in one embodiment being a spiral coil, is substantially concentric with the anode member to provided a uniform electric field around the anode member. In the preferred embodiment, spacing between turns of the spiral grid is equal to or less than twice the radial distance between the anode member and the inside diameter of the grid. While an opening into the cavity can be covered with a window that is transparent to the radioactivity (the alpha and beta particles) for the retention of the counting gas, improved operation is obtained without a window for most applications.

Abstract: A wide range radiation dose rate meter for civil defense use, including a iger-Mueller tube used in a continuous counting mode and for measuring dose rates from the natural background to about 30. rads/hr., with an ion chamber arranged to measure higher dose rates up to 10,000 rads/hr. The instrument has a sample and record capability in which the selected radiation detector will have its output connected to a selected storage capacitor for a precise interval of time determined by a timing circuit and the storage capacitor will accumulate and hold a voltage proportional to the dose rate, which can be read by means of an electrometer at a later time. The instrument has a self contained hand cranked power supply and all components are selected for long shelf life.

Abstract: Proportional counters for the detection and measurement of radioactive surface contaminations are provided with at least two flat window faces enclosing an angle and being formed by a thin foil spread or stretched by a framework including thin rods arranged along the inner edges of contacting window faces, to which rods the foil may be adhered. A perforated lattice or grid cage serves in particular to protect the thin window against any contact, the cage provides for a spacing of about double rod thickness between the framework and the controlled surface. Preferred is a polygonal and in particular hexagonal lattice whose grid wires or strips do not lie in the main scanning direction. Particularly convenient for checking pipelines are, for example, cylindrical measuring probes comprising window foils extending over and perhaps adhered to a circularly arranged frame of thin rods.

Abstract: A radiation dose-rate monitor is provided which operates in a conventional linear mode for radiation in the 0 to 0.5 R/h range and utilizes a nonlinear mode of operation for sensing radiation from 0.5 R/h to over 500 R/h. The nonlinear mode is achieved by a feedback circuit which adjusts the high voltage bias of the proportional counter, and hence its gas gain, in accordance with the amount of radiation being monitored. This allows compression of readout onto a single scale over the range of 0 to greater than 500 R/h without scale switching operations.

Abstract: A radiation detector has a plurality of detector collection element arrays immersed in a radiation-to-electron conversion medium. Each array contains a multiplicity of coplanar detector elements radially disposed with respect to one of a plurality of positions which at least one radiation source can assume. Each detector collector array is utilized only when a source is operative at the associated source position, negating the necessity for a multi-element detector to be moved with respect to an object to be examined. A novel housing provides the required containment of a high-pressure gas conversion medium.

Abstract: In a method of sensing the position of a neutral particle, the particle is received in one of two spaced parallel cathode arrays, each of which comprises a plurality of metal strips arranged adjacent and edge to edge, the strips in one array being orthogonal to the strips of the other array, and the metal of which the strips are formed being such that a neutral particle is converted to a fast electron which escapes from the cathode. Between the two cathode arrays is an anode array consisting of parallel wires held at a known electrical potential and surrounded by a gas. The fast electron is converted to an avalanche of electrons and positive ions; the presence of the ions induces an electrical charge in at least one strip of each cathode array; and the presence of the charges is sensed to determine an orthogonal position.
