Cyclotron terminology
1 Scope
This document specifies terms and definitions related to cyclotron classification, physics, and engineering.
This document applies to cyclotrons, and other types of accelerators can also be used as a reference.
2 Normative references
There are no normative references in this document.
3 Cyclotron classification
3.1 General concepts
3.1.1
Cyclotron
A device that uses a magnetic field to make charged particles in a cyclotron motion and is accelerated by a radio frequency electric field in motion.
[Source. GB/T 34127-2017, 3.1, with modification]
3.2 Classification by beam focusing method
3.2.1
Classic cyclotron
The first type of cyclotron that has cylindrical magnetic poles, the magnetic induction intensity decreases slowly in the radial direction.
3.2.2
Synchrocyclotron
It has the magnetic induction intensity that decreases in the radial direction, and the frequency of the radio frequency electric field gradually decreases during the ion acceleration process to make the ion and the accelerating electric
A cyclotron with a stable phase relationship between them.
[Source. GB/T 4960.1-2010, 8.25, with modification]
3.2.3
Isochronouscyclotron
The magnetic induction intensity grows synchronously with the energy of the accelerated ion along the radius, so that the cyclotron frequency of the ion is always maintained during the acceleration process
Constant cyclotron.
3.2.4
Sector-focused cyclotron
A cyclotron whose magnetic field intensity varies with azimuth angle; azimuthaly varying field cyclotron; AVF
A fan-shaped magnetic pole is used to generate an azimuth-modulated magnetic field, which maintains strict resonance acceleration to increase the energy of accelerated particles.
Speed device.
Note. Sector-focused cyclotron is the main form of isochronous cyclotron. According to different fan-shaped magnetic poles, fan-shaped focus cyclotrons can be divided into
Thomas cyclotron (3.2.5), spiral cyclotron (3.2.6), split fan cyclotron (3.2.7).
