摘要： An NMR probe head (3) has a coil system (9) and a radial centering mechanism for a sample vial (4) having two centering devices spaced axially from each other to center the sample vial in the radial direction only. The first centering device (5) is disposed above the receiver coil system and at least one further centering device (6) is disposed axially above the coil system with an axial spacing (d) above the first centering device. The first and second centering devices restrict the radial scope for movement of the sample vial to such an extent that the sample vial cannot touch an endangered space (7) during the entire duration of transport of the sample vial to its measuring position, thereby precluding damage to the probe head components in the endangered space by the sample vial.

摘要： An NMR apparatus includes a superconducting magnet coil system configured to generate a homogeneous magnetic field, and a helium (He) tank having an inner tube mechanically rigidly connected to the He tank and in which the magnet coil system is positioned. The He tank is configured to contain liquid helium to cool the magnet coils. A radiation shield has a radiation shield inner tube encompassing the He tank and spaced from the He inner tube to create a space between the He inner tube and the radiation shield inner tube to reduce an evaporation rate of the liquid helium. The NMR apparatus additionally includes a field shaping device with a magnetic material arranged in the space, in order to shim the homogeneous magnetic field. The field shaping device is fixed in the space so as to be in rigid mechanical contact with the He tank but without contacting the radiation shield.

摘要： An electrical circuit with one or more semiconductor components (10) is characterized in that at least one semiconductor junction of at least one of the semiconductor components of the electrical circuit is disposed such that the average direction of motion of the charge carriers in the semiconductor junction is essentially parallel to the lines of force of the magnetic field B0, wherein the corresponding semiconductor component is disposed directly on a substrate (12), which is made of a material with good thermal conduction properties. In this way, undistorted characteristics of the semiconductor component used can be ensured despite the very strong magnetic field and the low operating temperatures.

摘要： A method for converting a cryostat configuration (1) having a first container (2) with a liquid helium bath (3) and a second container (6) which is filled with liquid nitrogen (7) is characterized in that a cooling medium (12) which is in a gaseous state at a temperature of 60K and a pressure of 1 bar, is introduced into the second container and is cooled by a refrigerator (16) by means of a cooling circuit (11), the coolant lines of which are guided into the second container, to an operating temperature of ≦60K. With this retrofit for existing cryostat configurations that utilize both liquid helium and also liquid nitrogen for cooling a superconducting coil, use of liquid nitrogen can be completely avoided and the evaporation rate of the liquid helium can also be considerably reduced without having to re-liquefy the cryogens used.

摘要： An NMR measuring configuration has a temperature control device for a sample vial (1). The temperature control device has a temperature sensor with supply wires which are both surrounded by a sensor tube (15). The sensor tube (15) is connected to a measurement space via a sensor flow inlet (26) in such a way that a partial flow of a temperature-control fluid flows as a temperature-control flow (16) into a free space (17) between the temperature sensor and the inner wall of the sensor tube along the supply wires and flows out of the sensor tube via a sensor flow outlet (18) at the opposite end of the sensor tube. This minimizes both the temperature penetration factor and the difference between the sensor and sample temperatures (ΔTp).

摘要： A method for nuclear magnetic resonance (NMR) or magnetic resonance imaging (MRI) measurements, includes creation of enhanced polarization of nuclei of a first kind within a sample in a magnetic field at cryogenic temperatures and transfer of the polarized sample to room temperature. The enhanced polarization of nuclei of the first kind is thereby transformed into long-lived states (LLS) of nuclei of a second kind and these LLS are sustained. The LLS is at least partially converted into observable magnetization and an NMR or MRI measurement is carried out. The method allows one to extend the time needed between hyperpolarized magnetization and NMR detection.

摘要： A method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprises preparation of the sample and carrying out an NMR spectroscopy measurement. Preparation includes excitation of long lived coherences (LLC) between the singlet state S0 and the central triplet state T0 of nuclei of the sample. The thermal equilibrium Boltzmann distribution (Iz+Sz) is thereby transformed into a difference (Iz−Sz), which is flipped to the transverse plane, and irradiation of the sample with an rf-field is initiated. The LLC is sustained by maintaining the rf-irradiation during an interval t1 and the LLC is converted into observable magnetisation by interrupting the rf-irradiation. The method allows nuclear magnetic resonance spectroscopy measurements with improved spectral resolution.
