Description

technical field [0001] The invention relates to a solenoid magnetic field measurement system and a using method thereof, belonging to the field of accelerator magnetic field measurement. Background technique [0002] Since the electron cooling method was proposed by the former Soviet scientist Budeker in 1966, it has achieved remarkable development in the field of heavy ion accelerator engineering, and has been widely used in some large-scale accelerator experimental devices. The principle of electron cooling is to inject a certain required electron beam into the heavy ion beam. When the electron beam moves parallel to the heavy ion beam at the same speed, the Betatron oscillation of the ion beam will be reduced through the Coulomb interaction (that is, the particles in the circular accelerator The lateral motion in is a constrained oscillation about the design orbit). This is because the light electrons take away a large part of the ion energy through the Coulomb scatterin...

Problems solved by technology

[0004] Measuring the deviation data between the solenoid magnetic axis and the mechanical axis is essential in the installation and use of electronic cooling solenoids. Traditional solenoid magnetic field measurement methods such as Hall plate point measurement can only obtain the data in the solenoid aperture. The magnetic field distribution of the solenoid cannot be measured to obtain the deflection angle between the magnetic axis and the mechanical axis; and the new test method such as the tension line measurement method can measure and calibrate the magnetic axis of the solenoid, but the equipment is complex, expensive and the measurement process is cumbersome.
