Detection circuit design and fabrication for low-field RASER-NMR

Stelle frei: Ab sofort

Beschreibung

Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique that uses the magnetic properties of selected atomic nuclei (i.e. 1H, 13C, 15N, 19F) to investigate molecular structures and the dynamics of processes. The detection signal can be amplified up to sub-millihertz range with RASER (Radio-frequency Amplification by Stimulated Emission of Radiation), which is an innovative technique in magnetic resonance. RASER operational principles are similar to a laser, but in the radio-frequency domain, where it creates a population inversion in nuclear spins, typically using para-hydrogen as a pumping mechanism, and coupling it with a high-Q resonator to achieve stimulated emission of radio waves.
In our research group in the Institute for Microstructure Technology (IMT), we focus on the on the developing of the novel approach for NMR-RASER at low magnetic field (1µT - 10mT), which allows hyperpolarisation of atomic nuclei directly within the developed electromagnet system. The low magnetic field can be also utilized in specialized MRI imaging using extended hardware.
This project will involve tasks including:
• Resonator design for detection of various nuclei, e.g. 1H, 13C or 15N;
• Resonator assembly and system integration;
• Design and fabrication of components with machining or additive manufacturing;
• NMR spectroscopy with RASER and MRI at low magnetic field.

You will be part of a larger team within the Institute of Microstructure Technology (IMT), which offers you the possibility to fabricate and test the processes and devices and gives you the opportunity to co-author conference and/or journal publications. The position can be further extended to the Master Thesis.
