Ramsey Technique to Measure Ground-state Hyperfine Structure of Antihydrogen

Trainee: Amit Nanda
Supervisor: Eberhard Widmann

A Ramsey technique to measure the Ground-state Hyperfine Structure of Antihydrogen was integrated into an existing setup at the AD by Amit Nanda who was based at SMI in Vienna. He used this approach to measure the ground-state hyperfine structure of antihydrogen.

It is predicted that this will improve the precision of this measurement by a factor of 10 and thus provide one of the most sensitive tests of CPT invariance ever performed. For this purpose, he worked on the optimization of a hyperfine spectrometer line with two cavities through simulations in collaboration with other AVA Fellows.
