摘要： An ICR cell (01) operates with a duplexer (08), which is an integral part of a transmission and receiving device (09) of an FT-ICR mass spectrometry device. The device transmits a transmitter (03) voltage to at least one electrode (11) of the ICR cell during an ion excitation phase and protects a preamplifier (04) from overvoltage. An ion received signal passes through a reception path (12) to the preamplifier during an ion detection phase. The duplexer has at least one active serial switch (07) with two switchable states, each with different series impedances, which is inserted in the reception path (12). As a result, a duplexer for an ICR cell of an FT-ICR mass spectrometry device is provided in which at least one electrode can be used for both ion excitation and for subsequent ion detection.

摘要： A method for producing hyperpolarized sample material for use in magnetic resonance investigations involves preparing a target material containing high γ nuclei with a short T1, a polarizing agent with a broad EPR line, and low γ nuclei with a long T1. The polarizing agent in the target material is irradiated with microwave radiation, wherein the target material is at a cryogenic temperature and exposed to a static magnetic field B0≧4.0 T, thus polarizing the high γ nuclei by DNP, and the polarization is transferred from the high γ nuclei to the low γ nuclei by Cross Polarization. A dissolved sample material is prepared containing the hyperpolarized low γ nuclei from the target material. Nuclei with a long longitudinal relaxation time T1 can thereby be quickly hyperpolarized to a high polarization level.

摘要： An antenna configuration for use in a magnetic resonance apparatus has at least two individual antennas which each include at least one conductor loop, one tuning network and one matching network, wherein the individual antennas are each combined into separate modules which are positioned on and mounted to a support body and can be removed therefrom in a non-destructive fashion, is characterized in that the individual antennas are connected to each other through decoupling elements, wherein the decoupling elements are mounted to the support body in an undetachable fashion. It is thereby possible to define individual antenna modules which can be arranged in a simple fashion around the measuring volume, are also electromagnetically decoupled from each other, and can be positioned close to the measuring volume in order to ensure that the received MRI image has a maximum, high signal-to-noise ratio.

摘要： A method for producing a superconductive wire, whereby an elongated intermediate element is formed out of an initial element in a deformation step and whereby the superconductive filaments are formed by a final reaction heat treatment, is characterized in that prior to the final reaction heat treatment the filaments in the intermediate element are densified in one or more high pressure densification steps following up the deformation step, said densification steps comprising a simultaneous action of at least four hard surfaces perpendicular to the axis of the elongated intermediate element, building up high pressure P≧100 MPa on a part of the intermediate element having an axial length L. This leads to a substantial increase of the critical current density Jc, whereby the anisotropy factor Γ is be almost not affected thus enabling production of almost isotropic wires or tapes.
