摘要： An NMR probe head has a capacitor with a dielectric (5), which surrounds a cavity (15) in which a capacitor piston (7) is disposed. A sliding bush (9) has a through hole (16) in which a piston operating rod (8) extends. The piston operating rod (8) is connected to a piezo-electric actuator and to the capacitor piston (7) in such a way that it displaces the capacitor piston linearly when a sawtooth voltage is applied to the piezo-electric actuator. The sliding bush thereby applies braking friction to the piston operating rod during linear displacement of the capacitor piston and only allows the piston operating rod to slide through during the steep edges of the sawtooth voltage. This avoids the disadvantages of prior art, wherein the NMR probe head remains compact and the material cost and manufacturing complexity are reduced.

摘要： A method for indicating the level of a liquefied gas in a cryogenic tank having a resistance temperature detector (1). The controller applies a heating pulse to the detector and performs a single resistance measurement after the heating pulse. The overheating of the sensor and the time interval for the measurement are found in a separate set of test experiment. As a result, for temperature sensors with negative temperature coefficient, the resistance of the sensor in gas is below some unique characteristic value, which can be used like a threshold criterion to distinguish between the liquid and the gas in a wide temperature range. For sensors with positive temperature coefficient, the resistance of the sensor in gas is larger than some unique characteristic value, which can be used like a threshold criterion to distinguish between the liquid and the gas in a wide temperature range.

摘要： A transport device for transporting an NMR sample to the probe head (16) of an NMR spectrometer by means of a transport system (12) is characterized in that the transport device comprises a shuttle (15) adapted for use with a transport system. The transport system is structured to transport an HR-NMR sample spinner or an NMR MAS rotor (5). The shuttle includes a locking device for the NMR MAS rotor, the locking device being formed such that the NMR MAS rotor is released by unlocking the locking device and can be transferred to and received by the NMR MAS probe head. It is therefore possible to rapidly change from NMR spectroscopy of liquids to NMR spectroscopy of solids, and vice versa, simply by exchanging the probe head, without converting the transport system.

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 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 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： In a coil arrangement for nuclear magnetic resonance comprising a main coil (13), a shielding coil (14), and at least one correction coil (41), the function of which consists in forming a magnetic field gradient with eddy current properties which are as good as possible, the main coil (13) and the shielding coil (14) are electrically connected in series with the correction coil (41). The deviations of the residual field from the desired design generated by production tolerances are thereby modified by the correction coil in such a fashion that the long-lasting eddy currents are suppressed. This either reduces the waiting time that must lapse after a gradient pulse before a predetermined field homogeneity is achieved or e.g. the deviations from the desired field are minimized in imaging applications.

摘要： A magnet assembly for generating a magnetic field (H) in the direction of a z axis in a working volume (AV) comprises an actively shielded superconducting magnet coil system (M) and at least one current path (P1, . . . , Pn) which is superconductingly closed in the operating state. The actively shielded superconducting magnet coil system (M) has a radially inner partial coil system (C1) and a radially outer partial coil system (C2) disposed coaxially with respect to each other. An external device supplies current to the current paths (P1, . . . , Pn) to charge each path to a respective current (IP1, . . . , IPn) in the operating state. When optimizing the fringe field behavior outside of the magnet system, the overall magnitude of magnetic dipole moments of the current paths (P1, . . . , Pn), charged to their respective operating currents (IP1, . . . , IPn), is at least 0.1% of the magnitude of the magnetic dipole moment of the charged partial coil system (C2). When charging the current paths (P1, . . . ,Pn) to their respective operating current (IP1, . . . , IPn), the resulting change nullH2 of the coefficient of second order (H2) of the polynomial expansion of the magnetic field (H) of the magnet assembly is given by: nullnullH2null
