Dear all, Join us for the next QUBITS Seminar on September 24, 2025, where Hans Stærkind, postdoctoral researcher at the Niels Bohr Institute (University of Copenhagen), will give a talk entitled: ”Optical Magnetometry for MRI” Date: October 27, 2025 Time: 14:15–16:00 Location: Aud G2, 1532-122 (NOT iNANO!) Format: 45-minute talk followed by discussion and refreshments All are welcome! Drinks and snacks will be served after the talk. Please accept this calendar invitation if you plan to attend—it helps us estimate catering needs.

ABSTRACT In this talk, Hans Stærkind will present the novel EXAAQ magnetometer. It is a high-field optical quantum magnetometer based on saturated absorption spectroscopy on the extreme angular-momentum states of the cesium D2 line. With key features including continuous readout, high sampling rate, and sensitivity and accuracy in the ppm range, it represents a competitive alternative to conventional techniques for measuring magnetic fields of several teslas. The prototype has four small separate field probes, and all support electronics and optics are fitted into a single 19-inch rack to make it compact, mobile, and robust. The field probes are fiber coupled and made from nonmetallic components, allowing them to be easily and safely positioned inside a 7 T MRI scanner. He will discuss how this system can be used for improving image quality in MRI, by detecting imperfections in the magnetic field gradients that are played out during an MR scanning sequence. → Please forward this invitation to interested colleagues who may not already have signed up for information from QCA.
