摘要： The invention relates to a particle beam therapy system (2) comprising an accelerator (4) for making a beam of charged particles available, a beam guiding unit (10, 10a, 10b; 10b*) which supplies the beam to a treatment location (18) starting from the accelerator (4), at least one beam property monitor (28; 28*) arranged along the beam path (6), and a control unit which communicates with the beam property monitor (28; 28*) and the beam guiding unit (10, 10a, 10b; 10b*) and which determines deviations of the actual properties from the desired properties of the beam and transmits control signals for adapting the beam properties to the beam guiding unit (10, 10a, 10b; 10b*), using said deviations. The aim of the invention is to devise a particle beam therapy system which allows a precise guidance of the beam even during a treatment, especially during a particle beam therapy method. This aim is achieved in that the beam property monitor (28; 28*) is arranged on the periphery of the beam perpendicular to the beam path (6) in such a manner that the beam properties are detected due to their direct interaction with particles of the beam in the halo region (36) and/or indirectly by electromagnetic interaction. The invention also relates to a method for guiding a beam of charged particles in a particle beam therapy system.

摘要： A radiometric measuring device is described for measurement of a physical parameter of a fill material (1) located in a container, and for output of a measured signal which corresponds to a measured value of the physical parameter. Said measuring device has a single line pair (17) via which power is supplied to the entire measuring device and via which the transmission of the measured signal occurs, and has a radioactive emitter (5) which, during operation, sends radioactive radiation through the container (3), and has a detector (7) with a scintillator (9) and a photomultiplier (11) which is used to detect a radiation intensity penetrating through the container (3)as a function of the physical parameter to be measured, and to convert said parameter into an electric output signal (N), with measuring device electronics (15) which are used to create the measured signal (M) based on the electric output signal (N) of the detector (7) and to make available said measured signal via the line pair (17), with an energy accumulator (27) powered via the line pair (17), with a controller (45) which triggers measurement phases as a function of the energy available via the line pair (17) and the energy accumulator (27), during which the measuring device measures the physical parameters, and which puts in operation the photomultiplier (11) exclusively during the measurement phases, wherein the large voltages needed for operation of the photomultiplier (11) are created during the measurement phases by means of a high voltage cascade (31).

摘要： An insulating tube (9) has one end and the other end. An avalanche photodiode (APD) (15) is disposed outside the one end of the insulating tube (9). The other end of the insulating tube (9) is hermetically connected to an outside flange through a stem inner wall (61). Capacitors (C1, C2) electrically connected to the APD (15) are provided inside the insulating tube (9) and serve to remove the DC current from the signal generated by the APD (15) when it detects electrons. Since the capacitors (C1, C2) are provided inside the insulating tube (9), the response of the output signal is prevented from degrading.

摘要： A method and apparatus for radiography, and especially for planar beam radiography, and also a detector for detecting incident radiation. In the method and apparatus, wherein X-rays (9) are emitted from an X-ray source (60), the X-rays are formed into a planar beam and are transmitted through an object to be imaged (62), and the X-rays transmitted through said object (62) are detected in a detector (64). The detector (64), which detects incident radiation is a gaseous parallel plate 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 ionization electrons released by incident radiation. The detector (64) is oriented, in relation to the incident radiation (9), so that the radiation enters sideways between a first and a second parallel plate, between which the electrical field is created. Electrical signals induced by said electron-ion avalanches are detected in at least one detector electrode arrangement, including a plurality of detector electrode elements arranged adjacent to each other, each along a direction being essentially parallel to the incident radiation. Pulses from each detector electrode element are processed in processing electronics, for obtaining values for each pixel corresponding to the respective detector electrode element.

摘要： In a method for optimizing an ion detector a control voltage, such as in a mass spectrometry system, an array of mass scan data is acquired. Based on the size of the largest peak in the array or part of the array, a determination is made as to whether the current detector gain should be changed to a new detector gain. If the current detector gain should be changed, the control voltage for the subsequent mass scan is adjusted to a new control voltage corresponding to the new detector gain. The data are scaled based on the current detector gain. In another method, a gain versus control voltage curve is generated for calibration. These methods may be implemented by hardware, software, analog or digital circuitry, and/or computer-readable or signal-bearing media.

摘要： An apparatus and method for detecting ionizing radiation are presented. The apparatus includes a scintillator adapted to convert incident ionizing radiation into light; a photocathode adapted to release photoelectrons in dependence on the light; an electron avalanche amplifier adapted to avalanche amplify the photoelectrons; and a readout arrangement adapted to detect the avalanche amplified electrons. The electron avalanche amplifier in one implementation is a gaseous avalanche amplifier including an array of amplification regions. A protective layer is provided to prevent the avalanche gas from coming into contact with the photocathode.
