APPARATUS FOR RADIAL MOVEMENT OF MAGNETIC MEASUREMENT SENSOR FOR COMPACT SUPERCONDUCTING CYCLOTRON

摘要

Disclosed is an apparatus for the radial movement of a magnetic measurement sensor for a compact superconducting cyclotron. The apparatus comprises a sensor sliding plate (1), an optical scale (2), a Hall sensor (3), a filament (4), a lead screw (10), a slider (11), a fixed pulley (12), a servomotor (13), a data transmission line (6), and a data collector (7). The servomotor (13) drives the slider (11) installed on the lead screw (10) to move up and down in a straight line. One end of the filament (4) is fixed on the slider (11), and the other end thereof is wound around the fixed pulley (12) to reach the middle plane of a magnetic field, then turns to a horizontal direction and is connected to the sensor sliding plate (1), and finally is wound around the fixed pulley (12), forming a closed loop system. The Hall sensor (3) is arranged on the sensor sliding plate (1). The data transmission line (6) is connected to the Hall sensor (3) and the data collector (7). The apparatus has the advantages of a compact structure, accurate positioning, easy operation, accurate measurement, automatic data collection etc., providing important and accurate data for the calculation of magnetic field shimming and ion beam flow dynamics.
