The electron magnetic moment has since become one of the most precisely measured properties of an elementary particle, providing stringent tests of the standard model of particle physics. The demonstration of an apparatus for measuring the magnetic moment of the electron\u2019s antiparticle\u2014the positron\u2014could enable new and exceptionally precise fundamental tests. Now a team led by Gerald Gabrielse of Northwestern University in Illinois has realized the first one-positron quantum cyclotron, which can store an individual positron while manipulating its quantized cyclotron and spin states [1].
