Two-symmetry Penning-Ioffe trap for antihydrogen cooling and spectroscopy
2020
Nuclear Instruments and Methods in Physics Research Section A : Accelerators, Spectrometers, Detectors and Associated Equipment
A B S T R A C T High-accuracy spectroscopic comparisons of trapped antihydrogen atoms (H) and hydrogen atoms (H) promise to stringently test the fundamental CPT symmetry invariance of the standard model of particle physics. ATRAP's nested Penning-Ioffe trap was developed for such studies. The first of its unique features is that its magnetic Ioffe trap for H atoms can be switched between quadrupole and octupole symmetries. The second is that it allows laser and microwave access perpendicular to
