Title: METHOD AND DEVICE FOR THE HYPERPOLARIZATION OF A MATERIAL SAMPLE
Abstract:
The invention relates to a method for the hyperpolarization of a material sample (4), which has a number of first spin moments (10) of a first spin moment type, wherein the number of first spin moments (10) is brought into interaction with a second spin moment (16) of a second spin moment type, wherein the first spin moments (10) are nuclear spin moments and the second spin moment (16) is an electron spin moment, wherein the first and second spin moments (10, 16) are exposed to a homogeneous magnetic field (B), wherein the second spin moment (16) is polarized along the magnetic field (B), wherein the second spin moment (16) is coherently manipulated by means of a, preferably repeated, sequence (S) having a number of successive high-frequency pulses (Pki, Pk'i) temporally offset to each by durations (Tki, Tk'i, T), in such a way that a polarization transfer from the second spin moment (16) to the first spin moments (10) occurs, and wherein durations (Tki, Tk'i, T) inversely proportional to a Lamor frequency (ωLarmor) of the first spin moments (10) in the magnetic field (B) are inserted between high-frequency pulses (Pki, Pk'i).
