4pi Magnetometry

Based on our expertise in precision measurements of magnetic fields, we are extending our field of research into magnetic field reconstruction, in particular by measuring the spatial distribution of magnetic fields using sensor arrays.

Spatial monitoring of magnetic fields and reconstructing their sources has an impact in several of our group's research fields, e.g., in better understanding the magnetic field generated by the human heart or in studying magnetic field disturbances in high precision experiments based on spin clocks.

We are seeking a highly motivated student who will, as a first step, design and realize a test setup with a spatial array of magnetic field sensors, develop the multi-channel readout DAQ system, and characterize the test setup.

The performance of the test setup is evaluated in the second part by reconstructing simple magnetic field sources as test cases. For this, a reconstruction algorithm has to be implemented and tested.

Students can learn to work with magnetic field sensors and DAQ systems and develop programming skills.

suitable as

• Bachelor’s Thesis Physics

Supervisor: Peter Fierlinger

Optical Atomic Magnetometer

Our group is actively developing optical atomic magnetometers, a type of sensors using light-atom interactions to detect magnetic fields.This approach, sitting on the junction of laser-optics, quantum-optics and atom-physics, offer a wide range of possibilities for undergraduate and graduate students, from theoretical approaches to practical experiments.

Possible thesis projects are: the Characterization of a non-magnetic Optical Atomic Magnetometer Array at the panEDM Experiment (at ILL), the Development of a non-magnetic Free Space Cesium Magnetometer, the Development of an Optical Earth Field Cesium Magnetometer, the Characterisation and Improvement of Cesium Vapor Cells and Upgrading and Characterisation of a Magnetically Shielded Test Chamber for Magnetometers.

Students can learn a variety of skills, such as handling laser optics and different measurement systems, designing sensors, or developing operating and analysis software.
