摘要： An apparatus with an increased efficiency, for ion bombardment machining operations at voltages not exceeding some few thousands of volts, is provided. It comprises an ion source whose plasma is extracted across grids forming cylinders of revolution about one and the same axis, for example a vertical axis. The specimens for machining are arranged in a ring around the ion source. The ion beam, of radial type, is highly uniform within a cylindrical space defined between two parallel planes, for example horizontal planes. It is possible to limit the apertural angle of the beam by the use of a mask arranged against one of the grids.

摘要： A device is provided for adjusting electron-optical apparatus. The specimen to be scanned is equipped with a marker emitting back-scattered electrons. A transducer, in response to these electrons, emits a signal which unblocks the modulating electrode of a cathode ray tube used for the display purpose. The tube screen has long persistance characteristics; the beam and the object holder being displaced in four mutually perpendicular directions by theoretically corresponding quantities, the adjusting errors are visible immediately.

摘要： The invention relates to detectors of ionizing radiation which use a photoconductor as the detecting element. The invention lies in an electrode moving in a direction OX through a photoconductive medium disposed between two grids of electrodes extending parallel to OX. During the irradiation time, the grid electrodes of one grid are raised to a positive potential relative to the electrodes of the other grid and electrons and positive ions are created in the photoconductor. The electrons are removed by maintaining the positive potential on the electrodes of said one grid for a period of time longer than the irradiation. During displacement of said moving electrode, only the positive ions give rise to current in the electrodes. The invention is applicable to radiotherapy and radiography.

摘要： A sample on which pre-established patterns are to be defined is rigidly fixed to a moving object-holder and subjected to bombardment with a beam of charged particles by means of a microlithographic system. This system comprises an array of elements placed in one plane in a predetermined spatial configuration and an imaging system having a magnification which is considerably less than unity, the elements being each capable of assuming two distinct states. A narrow beam of charged particles which emerges from each element is on-off modulated according to the state assumed by the element under the control of logic circuits.The plane of the sample is adapted to correspond to the plane of the elements with respect to the imaging system and the elements are disposed at the intersections of the lines and columns of a matrix. The logic circuits permit the sequential application of a suitable voltage in accordance with a program which is pre-established in relation to the patterns to be drawn and in synchronism with the displacement of the object-holder.

摘要： The invention relates to the alignment of designs in two near planes, whereby one (the mask) carries a design which is to be reproduced on the second (the pattern).The invention relates to a method for the optical alignment of these two planes using a pair of marks formed by a lens (4) having linear Fresnel zones inscribed on the mask (1) and a reflecting grating (3) of appropriate width inscribed on the pattern (2). The illumination by a parallel beam of monochromatic light of the lens with Fresnel zones produces on the pattern a substantially rectangular illumination spot which, when made to coincide with the line inscribed on the pattern is reflected or transmitted, and supplies a detected intensity maximum or minimum depending on whether the lines reflects more or less than the remainder of the pattern. The invention also relates to an optical alignment apparatus for performing this method.The invention applies to the alignment of lithographic X-ray masks or photographic masks with respect to patterns on which reproduction is to take place.

摘要： The disclosure concerns radio-therapy machines and installations. The precise position of a patient is verified by means of a device mounted on the movable arm of a mount with isocentric motion. This device includes a system for scanning by a light beam. The position of the source of this light beam corresponds to the position of radiation source. The device further has a system for the optical detection of the point of impact of the light beam on the patient. These two systems enable the position of the point of impact to be determined by means of a data-processing system.

摘要： Problems related to acquistion time with reconstructed image type tomographs are resolved by causing step by step rotations of the X-ray tube/multiple detector set of this tomograph and, at each step, by causing a translational movement of this set in order to scan the entire region to be examined of a body under examination. It is shown that, by using a multiple row multidetector, it is possible, at equal speeds, to improve the quality of the images produced or, at equal quality, to increase the acquisition speed. Furthermore, this mode of operation is especially well suited to the monitoring of radiotherapy action where the practitioner, when acquiring images, needs to be able to touch the patient.
