Description
The ALPHA Collaboration recently determined the antihydrogen ground-state hyperfine splitting to a relative precision of 4 ppm, an improvement of two orders of magnitude.
Achieving this leap required advanced in situ diagnostic and magnetic field characterization methodologies to mitigate the extreme sensitivities of driving resonant microwave transitions within a deep magnetic minimum trap. The talk will focus on the critical in situ diagnostic strategies and real-time magnetic field characterization techniques developed to track environmental drifts and map the trap's landscape.
