摘要： The present invention refers to a method for detecting position and arrival time of accelerated particles, particularly in a linear particle accelerator, and to an apparatus for carrying out said method. When a correction is triggered, the apparatus according to the invention digitally processes a triggering signal by means of a programmable digital synthetic system being set in a manner that it is equivalent, referring to the time response, to the analogue correction signal received. The output from said synthetic system is deducted from the measurement, therefore, the correction signal is entirely deleted from the measurement. A special adaptive algorithm takes care for the time response compliance of the synthetic system with alterations in the analogue circuit generated due to the warming of the circuit itself.

摘要： Methods are described wherein the signals from various sensors that monitor parameters such as beam position, beam intensity at each turn, number of turns, extracted current, extracted beam profile in space and energy are used to determine the effect of the variation of different parameters that control the operation of an accelerator. The diagnostic measurements and adjustments may be based upon measuring and evaluating parameters as a function of turn, and are part of an automated feedback loop for achieving the proper automated operation. The methods can be used to establish proper operating values for the accelerator parameters for optimum beam operation. By the use of feedback the operation of the accelerator can be automatically controlled in real time.

摘要： A particle therapy system capable of confirming energy of an accelerated charged particle beam before the charged particle beam is irradiated to an irradiation target. A beam position monitor is disposed in a synchrotron, and a cavity voltage monitor is associated with an RF cavity for acceleration. An ion beam orbiting within the synchrotron is accelerated with application of an RF voltage applied to the RF cavity and is extracted from the synchrotron with application of an RF voltage applied to an RF knockout electrode. Based on a cavity voltage signal detected by the cavity voltage monitor, a frequency counter measures the frequency of the RF voltage applied to the RF cavity. Based on a voltage detected by the beam position monitor, a beam signal processing unit measures the position of a beam orbit. Based on the frequency of the RF voltage and the position of the beam orbit, the energy judgment processing unit determines whether energy of the ion beam after the end of the acceleration is normal or abnormal.

摘要： A first aspect of present invention is related to a method for controlling the extraction of ion beam pulses produced by a synchrocyclotron according to an irradiation plan. The synchrocyclotron comprises electrodes configured to be placed in a magnetic field, wherein an alternating voltage is applied between the electrodes, and wherein the frequency of the alternating voltage is modulated in a cyclic manner. The method comprises the steps of starting an acceleration cycle of the synchrocyclotron (12), generating a reference signal (38) when the modulated frequency reaches a predefined value (42), communicating the time, at which the reference signal (38) is generated, to the one or more beam control elements (20, 22), assessing one or more status parameters of the one or more beam control elements (20, 22), wherein the assessment is synchronised with the generation of the reference signal (38), cancelling or proceeding with the extraction of the beam pulse depending on the results of the assessment. A second aspect of the present invention is related to an ion beam extraction system configured to perform the method according to the first aspect of the present invention.
