Progress towards a sub-ppb measurement of the antiproton magnetic moment. Doctoral dissertation, Harvard University, Graduate School of Arts & Sciences.http://nrs.harvard.edu/urn-3:HUL.InstRepos:42013051The antiproton magnetic moment was measured for the first time using a single antiproton. This allowed a 680-fold improvement in precision, and a resulting value in Bohr magnetons of g/2 =2.792845 (12) . This first direct comparison of the antiproton and proton magnetic moments, resulted in a measured ratio of -1.000 000 (5), a stringent test of CPT. An apparatus that separates the particle excitation and detection was designed, constructed and partly demonstrated. The proposed measurement sequence and result is presented.application/pdfenantiprotonmagnetic momentThesis or Dissertation2019-12-110000-0002-6197-8366
