Towards Antihydrogen Confinement with the ALPHA Anithydrogen Trap
James Storey (TRIUMF, Canada)
Abstract
Antihydrogen is the simplest atomic system composed entirely of
antiparticles. Antihydrogen can be used to test CPT invariance
by comparing the spectra of hydrogen and antihydrogen atoms.
The ALPHA (Antihydrogen Laser PHysics Apparatus) project at
the CERN Antiproton Decelerator (AD) aims to confine antihydrogen atoms
and perform spectroscopy on the trapped antiatoms. The trapping
of antihydrogen is the principal goal of the first phase of the experiment.
This talk will present progress towards this goal.
