Description
We present the development of a novel Penning ion trap for precision spectroscopy of symmetry-violating electroweak properties using single trapped molecular ions [1]. The high magnetic field of the Penning trap can be used to Zeeman shift two molecular states of opposite parity to near degeneracy, enhancing the sensitivity of parity-violating nuclear properties by more than 11 orders of magnitude [2]. Hence, our proposed experimental setup is expected to provide highly sensitive measurements of symmetry violating nuclear properties across the nuclear chart. This contribution will describe the status of a cryogenic Penning trap for performing measurements in SiO+ and TlF+ molecules, as well as discuss future prospects of this technique.
