Towards Antihydrogen Confinement with the ALPHA Anithydrogen Trap

James Storey (TRIUMF, Canada)


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.
