William Bertsche

I am a Reader with the Accelerator Physics group of the University of Manchester Department of Physics and Astronomy and the Cockcroft Institute. I work on plasma physics and accelerator topics, as well as measuring fundamental properties of antimatter through atomic physics experiments using Antihydrogen atoms. I am a Deputy Spokesperson for the ALPHA experiment.

The ALPHA experiment at CERN routinely synthesizes and traps antihydrogen atoms. With this unique source of pure antimatter systems, we are able to perform precise measurements of its properties, from its spectral signature in various energies ranges to its behaviour in a gravitational field. This research aims to address the question of observed baryon asymmetry in the universe today: why is antimatter so much more rare than matter.
