A Beam Horizontal and Longitudinal Detector Device Based on Ceramic Vacuum Tube

Abstract

The present invention relates to a horizontal and vertical detector device based on a ceramic vacuum pipeline beam current, comprising: a ceramic vacuum pipeline, a periodic annular slotting unit, a 16-way broadband combiner unit, and a detector bracket for supporting the above-mentioned components; The two ends of the ceramic vacuum pipeline are respectively connected with the existing annular accelerator, which is used to provide a channel for the beam; the periodic annular slotting unit is sleeved on the outer surface of the ceramic vacuum pipeline, and there is a device for adjusting the ceramic vacuum pipeline inside. A plurality of electrodes for induction by the beam passing through the vacuum pipeline; the 16-way broadband combiner unit is arranged outside the periodic annular slotting unit, and is connected with each of the described periodic annular slotting units. The electrodes are connected, and are used to add and synthesize the sensing signals of the electrodes to obtain a correction signal and output it to a subsequent particle correction system. The invention can be widely used in the field of beam current cooling or beam current feedback of heavy ion beams (including proton beams) circular accelerators.

Description

technical field [0001] The invention relates to a beam flow transverse and longitudinal detector device based on a ceramic vacuum tube, which belongs to the beam cooling or beam feedback field of heavy ion beams (including proton beams) circular accelerators. Background technique [0002] The beam random cooling technology uses a broadband microwave feedback system to cool the beam. The beam detector located upstream of the beam detects a radio frequency signal proportional to the particle deviation. This output signal is filtered, delayed, phase-shifted and After the amplification system is added to the downstream impactor, the particles are corrected proportional to the deviation on the impactor, so as to achieve the purpose of cooling. Of course this requires that the correction signal arrives at the impactor synchronously with the particle. The stochastic cooling system is mainly composed of beam horizontal and vertical detectors, low noise amplifiers, microwave bridges...

Problems solved by technology

Most of the beam detectors of the stochastic cooling system currently in operation have the disadvantages of complex structure and low shunt impedance. For example, the beam detector of the random cooling system of the Antiproton Decelerator (AD) The super-electrode (super-electrode) quarter-wavelength microstrip line structure, the total longitudinal shunt impedance of the two-meter-long structure is only 1600Ω, that is, 800Ω / m
