Abstract

The invention relates to a beam position detector for a proton and heavy ion synchrotron and a use method. The beam position detector comprises a pole plate assembly, a vacuum feed-through assembly, an isolation ground assembly and a vacuum pipeline, the polar plate assembly is fixedly arranged on the inner wall of the vacuum pipeline through the supporting column assembly and is separated through the isolation ground assembly; the vacuum feed-through assembly is arranged on the outer wall of the vacuum pipeline, and the vacuum feed-through assembly is respectively connected with the polar plate assembly, the amplifier and the corresponding load; two vacuum pump ports are symmetrically formed in the two sides of the vacuum pipeline, and the two vacuum pump ports are connected with a vacuum pump through a vacuum pump pipeline, so that the vacuum pipeline keeps a preset vacuum degree; the polar plate assembly induces a beam to be detected entering from the upstream of the vacuum pipeline, and an induction signal is sent to subsequent processing equipment through the vacuum feed-through assembly and the amplifier to be processed. The method can be widely applied to the field of proton heavy ion beam accelerator beam diagnosis.

Description

technical field [0001] The invention relates to a beam current position detector for a proton heavy ion synchrotron and a using method thereof, belonging to the field of beam current diagnosis of proton heavy ion beam accelerators. Background technique [0002] As the eyes of the accelerator, the beam diagnosis system is one of its important systems. The beam transmission and the determination of the performance and parameters of the accelerator are monitored through the measurement of the beam parameters by the beam diagnosis system. Necessary means of matching. Among them, the beam position detector is a necessary measurement element for the operation and debugging of the accelerator. Accurate circle-by-turn position and closed-track measurement are of great significance for the optimization and research of the accelerator. [0003] High-current annular ion accelerators require beam position detectors with low beam coupling impedance, less resonance, and high position sen...
