摘要： A radiation detector arrangement for imaging of an object comprises multiple line detector units, each being arranged for one-dimensional imaging of the respective ray bundle. The detector units are arranged parallel in a two-dimensional array. The detector units are sited in rows and stacks, the rows being parallel with the detector unit and the stacks being orthogonal thereto, where the one-dimensional detector units in each row are together capable of detecting the object in one dimension. A device is provided for moving the detector units relative the object parallel with the stacks at least a distance corresponding to the distance between two adjacent detector units in the stacks.

摘要： A method and apparatus for radiography and also a detector for detecting incident radiation. In the method and the apparatus X-rays (9) are emitted from an X-ray source (60). Said X-rays which have interfered with an object to be imaged are detected (62) in a detector (64). The detector (64), which detects incident radiation is a gaseous avalanche chamber, including electrode arrangements between which a voltage is applied for creating an electrical field, which causes electron-ion avalanches of primary and secondary ionisation electrons released by incident radiation. The detector detects electrical signals in at least two detector electrode modules, said electrical signals being induced by electron-ion avalanches, in at least one of a plurality of detector electrode elements arranged adjacent to each other, each along a direction being essentially parallel to the incident radiation, and where the at least two independent detector electrode modules are arranged in close proximity to each other, each along a direction being essentially parallel to the incident radiation.

摘要： An apparatus for monitoring an electrically charged particle pulse includes at least one coil defining an opening therethrough. The coil generates a bipolar signal responsive to the electrically charged particle pulse passing through the opening, and the bipolar signal comprises a first portion having a first polarity and a second portion having a second polarity. Unipolar blocking diode connected to the coil passes the first portion of the bipolar signal having a first polarity and blocks the second portion of the bipolar signal having the second polarity. Monitoring Device connected to the unipolar blocking diode generates an output signal representative of a predetermined characteristic of the particle based upon the first portion of the bipolar signal which is passed by the unipolar blocking diode. In a preferred embodiment, the coil has a toroidal shape and comprises a plurality of windings electrically connected in parallel, and each of these windings comprises a plurality of conductive loops. The apparatus may also comprise a series of coils arranged so as to define a predetermined path for passage of the electrically charged particle through each respective opening of each respective coil.

摘要： A gated strip proportional detector includes a gas tight chamber which encloses a solid ground plane, a wire anode plane, a wire gating plane, and a multiconductor cathode plane. The anode plane amplifies the amount of charge deposited in the chamber by a factor of up to 10.sup.6. The gating plane allows only charge within a narrow strip to reach the cathode. The cathode plane collects the charge allowed to pass through the gating plane on a set of conductors perpendicular to the open-gated region. By scanning the open-gated region across the chamber and reading out the charge collected on the cathode conductors after a suitable integration time for each location of the gate, a two-dimensional image of the intensity of the ionizing radiation incident on the detector can be made.

摘要： A radiation detector arrangement for imaging of an object comprises multiple line detector units (41), each being arranged for one-dimensional imaging of the respective ray bundle. The detector units are arranged parallel in a two-dimensional array. The detector units are sited in rows (44; 61) and stacks (45; 63), the rows being parallel with the detector unit and the stacks being orthogonal thereto, where the one-dimensional detector units in each row are together capable of detecting the object in one dimension. A device (87-89, 91) is provided for moving the detector units relative the object parallel with the stacks at least a distance corresponding to the distance (s1~) between two adjacent detector units in the stacks.
