Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to an optical system for transfer of timing reference signal and radio frequency synchronisation of multiple events with femtosecond precision on multiple remote locations such as within a particle accelerator, where synchronisation scheme with a low phase jitter and a long term stability is required using standard telecommunications single-mode optical fibre. Said system comprises a transmitter (1), a low jitter oscillator (2) and a receiver (3), said transmitter (1) and said receiver (3) being connected by means of a transmission optical line (4) and a return optical line (5).

Abstract: The present invention refers to a method for compensating the non-linear distortions of high-frequency signals, especially when observing the amplitude modulated signals with narrow band receiver. The invention refers also to a device to carry out the said method. In the invention it is supposed that the ratio between the frequency fIN of the input signal SA and the sampling frequency fS that dictates the operation of the analogue-digital converter (3) is an arbitrary irrational number.
