Abstract: A method for detecting liquid on a windowpane in which radiation is emitted by at least one radiation emitter, the radiation is coupled into the windowpane via at least one optical element, and, after reflection in the windowpane, the radiation is coupled out of the windowpane. The radiation which is coupled out of the windowpane is captured in single measurements. A measurement cycle is formed from a multiplicity of single measurements. An average value is calculated from the measurement results of a measurement cycle. The average value is used a reference value for the single measurements of the subsequent measurement cycle currently in progress. The differences between the measured values of the single measurements of a measurement cycle currently in progress and the reference value are determined. The differences between the measured values of the single measurements of the measurement cycle currently in progress and the reference value are evaluated statistically.

Abstract: A DNP apparatus includes a cryostat (7) having an opening (8) and a loading path for a sample (1), the loading path extending from the opening to a sample receptacle (29), with a cryomagnet and a microwave source (2) as well as a configuration for supplying microwave radiation from the microwave source to the sample, which comprises a microwave path extending directly to the sample. The microwave path extends spatially separately from the loading path and the configuration for supplying microwave radiation has at least one microwave feed-through passing through one or more walls of the cryostat. The microwave path is incident on the sample from a direction opposite to the loading path or from a sideward direction at right angles to or at an inclination with respect to the axis of the loading path. This leads to simple and efficient polarization of the electron spins in the sample.

Abstract: 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.

Abstract: 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.

Abstract: 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 (?Tp).
