Problems solved by technology
With the emergence of compact accelerators, the longitudinal installation size of the beam measuring device is usually very limited. At present, beam position detectors in linear accelerators or transport lines usually use horizontal / vertical electrode pairs, or oblique 45-degree electrode pairs. Beam position measurement, the longitudinal installation size is relatively large

specific Embodiment
[0029] In electron linear accelerators and transportation lines, beam position measurement is an important core subsystem in the beam measurement system, and it plays an important role in accelerator debugging, operation and experimental research. The most commonly used non-intercepting measurement method for beam position measurement is beam position measurement based on detection electrodes, usually electrostatic detection electrodes, button electrodes, and stripline electrodes. The beam position detection bandwidth of the electrode type is very wide, from several hundred MHz to several GHz, and consists of a pair of electrodes or two pairs of electrodes (when measuring horizontal and vertical positions at the same time).

The invention discloses a button type beam position detector assembly with a compact structure, comprising a vacuum chamber, the side wall of the vacuum chamber is provided with a raised collimation target seat, and the side wall of the vacuum chamber is provided with four circular buttons Button-shaped electrodes, four circular button-shaped electrodes are symmetrically distributed in pairs with the axis that the collimated target seat runs through the center of the vacuum chamber as the axis of symmetry, and two circular button-shaped electrodes on the same side of the symmetrical axis run through the axis of the center of the vacuum chamber The included angle between them is 60 degrees, and the included angle between two axisymmetric circular button-shaped electrodes running through the center of the vacuum chamber is 120 degrees. The two ends of the vacuum chamber are fixed flanges, and six flange installation holes are arranged on the fixed flange, and the flange installation holes are threaded through holes. The round button electrode is located in the middle of the two flange mounting holes. The signal feed-out of the circular button-type electrode adopts the SMA type high-frequency broadband connector. A compact detector component design capable of beam position measurement in a vacuum chamber, the detector component can simultaneously measure the beam position in both horizontal and vertical directions, and the longitudinal structure is very small.
Description
Technical field [0001] The invention relates to a beam position detection technology, in particular to a button type beam position detector assembly with a compact structure. Background technique [0002] The beam position is one of the important parameters of the particle accelerator. The most basic method of measuring the beam position is to use the electromagnetic field coupled out of the beam by the detector. Since the charged particle beam is an electric current, it generates electric and magnetic fields. In the case of high-energy beams, these fields are pure transverse electromagnetic fields (TEM). If the beam deviates from the center of the vacuum chamber, the electromagnetic field coupled out of the beam will be modulated, so that the beam position information can be obtained. [0003] Usually, people use detection electrodes to measure the electromagnetic field of the beam. The induction signal of the detection electrode is a time-domain signal modulated by the beam cu...
