Permanent Magnet Quadrupole for the Final Focus
https://doi.org/10.25205/2541-9447-2024-19-3-72-80
Abstract
The paper presents the general theory of permanent multipole magnets and describes the design of a Halbach-2 type quadrupole magnet as a final focus lens for colliders and similar projects. Optimal positions of permanent magnet segments and conditions for quadrupole field generation are investigated. Characteristics of the quadrupole such as aperture, gradient, gradient integral, length and number of segments are given. The results of measurements and calculations as well as the possibilities for gradient adjustment are discussed.
