Title: Electron beam control assembly and method for a scanning electron beam computed tomography scanner
Inventor: RAND ROY EDWARD
IPC: H01J3/40
Filed: 1983-10-13
Granted: 1989-06-29
Abstract: An electron beam production and control assembly especially suitable for use in producing X-rays in a computed tomography (CT) X-ray scanning system is disclosed herein along with its method of operation. This assembly produces its electron beam within a vacuum-sealed housing chamber which is evacuated of internal gases, except inevitably for small amounts of residual gas. The electron beam is produced by suitable means within the chamber and directed along a path therethrough from the chamber's rearwardmost end to its forwardmost end whereby to impinge on a suitable target for producing the necessary X-rays. Since there is residual gas within the chamber, the electrons of the beam will interact with it and thereby produce positive ions which have the effect of neutralizing the space charge of the electron beam. However, there are a number of differentiel arrangements disclosed herein which form part of the overall assembly for acting on these ions and reducing the neutralizing effectthey would otherwise have on the beam.

Abstract: A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample and a first member of a specific binding pair with an end portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The first member of a specific binding pair is capable of binding the analyte. The strip contains a second member of a specific binding pair integral therewith for concentrating and non-diffusively binding the first sbp member at a small situs on the strip separated from the end portion of the strip. The detectible signal is produced in relation to the presence of the analyte in the test solution. The test solution passes through the situs as the test solution traverses the bibulous material. After the test solution has been allowed to traverse at least a portion of the strip, the strip is contacted with a developer solution containing members of a signal producing system in a manner that provides contact of the developer solution with the small situs following its contact with the test solution. The strip is then contacted with any remaining members of the signal producing system. The detectible signal produced at the situs is then compared with the signal detectible at a portion of the strip other than the situs to determine the analyte in the sample. In one embodiment of the invention the signal produced at the small situs has a sharp-edged distinctive pattern that provides a sharp contrast to the signal produced at adjacent sites on the strip when analyte is present in the test solution.
