Description
Technical Field
The invention relates to the technical field of accelerators, in particular to a transverse and longitudinal beam Schottky signal detector.
Background
Schottky (Schottky) diagnosis is a very important non-interception beam diagnosis means in the ion ring accelerator. When the particle beam passes through the Schottky probe, the Schottky probe can sense fluctuation statistical signals generated by the rotation of a limited number of particles, namely beam Schottky signals, and the signals mainly have the following three important applications: (1) measuring beam current intensity, energy, convolution frequency, frequency distribution width, momentum distribution width, a machine tune value and chromaticity parameters by using the Schottky signal, and carrying out machine research; (2) calculating a Schottky signal power spectrum, obtaining the proportional relation between Schottky power and ion number in the power spectrum, and carrying out measurement research on the mass and the service life of the atomic nucleus; (3) the Schottky signal is used as a pickup signal of a random Cooling (Stochastic Cooling) system and fed back to a bucker probe of the system, so that the particle orbit is synchronously corrected, the beam current is rapidly cooled, and the beam current quality is effectively improved.
At present, Schottky probes with different forms are arranged in each existing heavy ion and proton annular accelerator. For example, the german heavy ion research center GSI SIS18 schottky probes of the electrostatic induction capacitance (capacitance), ESR strip (strip) and quasi-resonant cavity (pill-box) types; the european nuclear center CERN large hadron collider LHC and RHIC of the us brugkian marine national laboratory BNL use slotted slow wave (slotted wave) type schottky probes. Capacitance type and cavity-like type Schottky probes are respectively arranged on a main ring CSRm and an experimental ring CSRe of a heavy ion accelerator cooling storage ring (HIRFL-CSR) in Lanzhou, China, and machine parameter research and nuclear life quality measurement are mainly carried out.
However, when the number of ions in the ring is small and the flow intensity is extremely low (such as low to micro-nano ampere level), the conventional signal detector has low sensitivity, is easily interfered by noise background and has poor signal-to-noise ratio, so that transverse and longitudinal signals of weak ion beams of the ring accelerator cannot be observed, and corresponding machine parameter research and nuclear life quality measurement experiments cannot be carried out.
