Abstract
Comparisons of trapped anti-hydrogen atoms and hydrogen atoms promise to test nature’s fundamental symmetries such as the charge conjugation parity time reversal (CPT) theorem. To be able to form and trap (anti-)hydrogen particles, nested Penning-Ioffe traps are used, which is a superposition of a Penning trap, responsible for trapping charged particles, and a magnetic Ioffe trap, responsible for confining neutral (anti-)hydrogen particles. Conventional, Ioffe traps, used at facilities such as ALPHA and ATRAP, constitute of superconducting wires and need to be cryogenically cooled. The aim of this research was to investigate whether it is possible to design an Ioffe trap, exclusively out of N52 (sintered NdFeB) magnets, which can trap (anti-)hydrogen particles. Using Comsol Multiphysics 6.0 software, magnetic flux density studies were conducted on three potential design models. It was found that for all models, it is possible to create a three-dimensional static magnetic minimum inside the traps with trap depth values ranging from 0.04K up to 0.21K. The research conducted in this paper is yet to be experimentally verified but suggests the possibility of constructing a cost-friendly alternative to conventional neutral traps.
