摘要： A method for inspecting a metallic component comprises providing an inspection standard having an eddy current signature substantially similar to an eddy current signature of the metallic component, wherein the inspection standard body is fabricated from a non-metallic material. The method also comprises inspecting the metallic component with an eddy current probe with reference to the inspection standard.

摘要： An ultrasonic inspection element and method of fabrication are provided for ultrasonic inspection of curved surface parts. Various points on a transducer are located. These points include the location where a ray starts, to the desired focal point in the material being inspected. The path of the ray is through a water medium and a water-metal boundary. These points are fitted onto a cylindrical surface. The ray is back propagated until it is focused at the desired focal point.

摘要： A method and apparatus for increasing response to low intensity radiation in a radiation detector includes a housing surrounding a chamber, a window adjoining the chamber, and a slot formed in one side of the chamber for admitting a circuit board into the chamber. The board supports an array of elongated detector elements on a surface thereof, an electrically conductive plate within the chamber and substantially parallel with the array of detector elements, sealant means in the slot surrounding the circuit board for providing a gas impervious seal, an ionizable gas contained in the chamber under high pressure, and a collimator mounted in a collimator support and positioned outside the chamber for directing ionizing radiation through the window for detection. The method comprises reducing the window thickness to a value below that required to withstand gas pressure in the chamber without distortion, and also comprises clamping the collimator support to the housing and against the window such that a major portion of the window abuts the collimator support and is externally supported thereby.

摘要： Method for improving signal response of a linear array ionization detector. The detector employs a detector assembly having plural closely-spaced detector elements mounted on a substrate with the assembly positioned in a high pressure, gas-filled chamber. Signal response is improved by cleaning the assembly and coating it with a moisture resistant material before insertion into the chamber.
