Abstract

The invention discloses a receiving end of a synchronizing system, the synchronizing system and a particle accelerator. A receiving end of the synchronization system comprises a synchronization terminal which is arranged between a sending end used for sending a reference signal and a phase processing device and comprises a sending end phase change obtaining device and a receiving end phase changeobtaining device; the phase processing device which is arranged between the synchronization terminal and the load, wherein the sending end phase change obtaining device obtains the phase change of thereference signal transmitted from the sending end to the synchronization terminal and transmits the phase change to the phase processing device; the receiving end phase change obtaining device whichswitches the conduction of the reference signal and the feedback signal from the load to the phase processing device according to a time sequence, so that the phase processing device obtains the phaseof the driving signal to be sent to the load based on the phase difference of the reference signal and the feedback signal at the receiving end phase change obtaining device and the phase change of the reference signal. Therefore, the phase locking precision of the sending end and the receiving end can be improved, and the precision of the synchronization system is improved.

Description

technical field [0001] The invention relates to synchronization technology, in particular to a receiving end of a synchronization system, a synchronization system and a particle accelerator. Background technique [0002] Today's large-scale particle accelerators require the index of the synchronization system to be on the sub-picosecond level, that is, two points separated by hundreds of meters or even kilometers in physical space are required to start an operation at the same time within an absolute time difference of sub-picoseconds , while it is well known that the time for light to travel one meter is about 3.3 nanoseconds, or about 3333 picoseconds. [0003] Usually, the method to achieve sub-picosecond synchronization is to divide a microwave radio frequency signal as a reference signal into two or more channels at the transmitting end, and transmit them to two or more receiving ends respectively. The phase-locking technology is then used to make the microwave signal ...
