摘要： An electronic interface (10) between a pure NMR receiver resonator (RO) and a preamplifier is characterized in that one or more control diodes (Dmatch1, Dtune1) are provided by means of which the current designed to flow through the switching diodes can be fed into these switching diodes, and the control diodes are connected to the switching diodes directly or via one or more additional series impedances. In this fashion, the impedance of the resonator is transformed to the required preamplifier or line impedance during the receiving process with little loss. In particular, during the receiving process, matching can be adjusted during the transmitting process, the current in the inductance of the resonator generated by the B1 field of the transmitting resonator is minimized and all components are protected against damage.
摘要翻译：纯NMR接收机谐振器（RO）和前置放大器之间的电子接口（10）的特征在于提供一个或多个控制二极管（Dmatch1，Dtune1），通过该控制二极管可设置流过开关二极管的电流进入这些开关二极管，并且控制二极管直接或经由一个或多个附加串联阻抗连接到开关二极管。以这种方式，在接收过程中谐振器的阻抗被转换为所需的前置放大器或线路阻抗，损耗很小。特别地，在接收处理期间，可以在发送处理期间调整匹配，由发送谐振器的B1场产生的谐振器的电感中的电流最小化，并且保护所有部件免受损坏。

摘要： A method for the transmission/reception of RF signals for NMR measurements uses a heat exchanger (1) for cooling heat sources (5), the heat exchanger having a contact element (4.2) for thermal connection between a cryogenic fluid and the heat source, is characterized in that the heat exchanger comprises a container having an interior volume VB into which a first cryogenic fluid F1 that has a liquid component F1L and a gaseous component F1G flows through an inflow conduit (8) and from which a second cryogenic fluid F2 that has liquid component F2L and a gaseous component F2G flows out through an outflow conduit (9). The inflow conduit has a flow cross-section QZ and a circumference UZ from which an associated parameter VZ=4·Q2Z/UZ results, wherein VB>10·VZ, and the outflow conduit has a flow diameter QA wherein QA≥QZ. The contact element is in close thermal contact with both the liquid volume component VL of the cryogenic fluid and with the heat source. A device for setting the inflow quantity of the first cryogenic fluid F1 into the container is provided that ensures a state F1L/F1G>F2L/F2G during operation. In this way, vibrations due to the cooling process can be largely reduced and the consumption of cryogenic fluid minimized.

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.
