THe-Trap is a Penning-trap mass spectrometer that aims to measure
the atomic mass ratio of tritium to helium-3 with a relative uncertainty
of 1 · 10−11 . To test the experiment’s accuracy and precision, we
measured the mass ratio of carbon-12 to oxygen-16, which is one of
the most precisely determined mass ratios [1].
In 2014 we reported a measurement of this mass ratio with a...

Low energetic neutrons are stored inside the apparatus searching for a
permanent electric dipole moment of the neutron at the Paul Scherrer
Institute. Precisely comparing the Larmor precession frequency of the
neutrons spins to that of cohabiting 199Hg atoms spins, allows to
investigate possible exotic short range spin-dependent interactions.
Such an interaction could be mediated by...

There has been for a while a large discrepancy between the values of the proton charge radius measured by the Lamb shift in muonic hydrogen and by
other methods. It has already been clear that theory of muonic hydrogen is
reliable at the level of this discrepancy and an error there cannot be a
reason for the contradiction. Still the status of theory at the level of
the uncertainty of the...
