Description
LSym is a new cryogenic Penning trap experiment that intends to test the
symmetry of matter and antimatter in the lepton sector. By measuring the coherent difference of their spin precession, the experiment will test for differences in mass, charge and g-factor of the positron and electron to achieve the most precise test for a hypothetical CPT violation for leptons so far. In the experiment we detect the particles motional frequencies via image current detectors. To further cool the trapped positron to its ground state of motion, the trap assembly is cooled to about 300 mK, where the trap cavity
is largely depleted from black-body photons around the cyclotron frequency of
140 GHz. In this poster our developments towards setting up our experiment
as well as our recent milestones will be illustrated.
