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： The present invention refers to a method for the precise measurement of dependency on amplitude and phase of a plurality of high frequency signals, preferably in the synchrotron accelerator of elementary particles. The essence of the solution according to the invention lies in that with a single measuring device and without any aliasing it is achieved a resolution of 0.2 micron and repeatability of measurements of 1 micron down to the lower frequency limit of a few MHz. A method according to the invention includes alternately directing, with a radio frequency (RF) switch, each analogue input signal to each of a plurality of RF processing units; amplifying each analogue input signal in each RF processing unit in order to adjust signals to the measuring range of a plurality of analog-digital (A/D) converters; directing each amplified analogue input signal to each of a plurality of A/D converters; converting the analogue signals to digital signals; directing the digital signals to a digital corrector; correcting the digital signals by means of correcting signals from the inverse models of evaluated systematic errors; collecting corrected digital signals in a digital switch and directing the ordered recombined number of digital signals to each of a plurality of digital receivers; and filtering the recombined number of digital signals in a plurality of low-pass filters.
