Measuring magnetic fields with Cesium for the n2EDM experiment

• Lea Segner

The n2EDM experiment aims to measure the neutron electric dipole moment with unprecedented sensitivity. Pushing for this level of precision requires tight control on systematic effects. For this reason, the magnetic field inside the experiment needs to be almost perfectly homogeneous. To ensure this, an array of 112 Cesium magnetometers will be used to measure and characterise the magnetic field to very high precision. In this talk I will present the importance of magnetometers for the n2EDM experiment, explain the measurement principle behind this magnetometer and present the experimental implementation of the Cesium magnetometers in the experiment.

Search for the EDM of Lithium-8, and other beta-radioactive light ions

• Chavdar Dutsov (PSI - Paul Scherrer Institut)

In this talk I will share with you a proposal for yet another experiment to search for electric dipole moments. I will show why it would be interesting to look for EDMs of very light beta-radioactive ions (Li-8, C-9 and others), why it is fun, nice and easy from a theory perspective and why it would be not-so-fun, not-so-nice and not-so-easy from experimental perspective. By studying ions without valence electrons we will bypass the significant screening from the electron shell that hampers state-of-the-art nuclear EDM searches with heavy neutral atomic and molecular experiments. Moreover, theoretical interpretation of results from a light ion like Li-8 can be done from first principles in comparison to the nuclear and proton EDM constraints currently derived indirectly from heavy systems like Hg-199. Lastly, I will shortly share my experience in applying for the SNSF Ambizione and the ERC Starting Grants.
