This project aims at investigating fundamental aspects of nonlinear magnetization dynamics of hyperpolarized spins by Dynamic Nuclear Polarization (DNP) in high magnetic fields at liquid helium temperatures using an electronically feedback-controlled radio-frequency maser : eFb RDCU-MASER-DNP.
Tests of the RDCU-MASER-DNP unit on the 300MHz NMR spectrometer of the Ecole Polytechnique, before installation at the LBM of ENS PARIS. The RDCU-MASER-DNP unit was built at the PMC laboratory.
