Abstract: A method for automatically assembling a solar field is provided with following steps: a) Providing at least one solar collector unit with a radiation concentrator collector including a radiation absorber with an absorber tube for a flow-through of a heat transfer medium and a parabolic mirror for focusing solar radiation onto the absorber tube of the radiation absorber for heating up the heat transfer medium flowing through the absorber tube; b) Transporting the solar unit to a target location of the solar field; and c) Assembling the solar unit on the target location of the solar field. Additionally a solar field with a plurality of prefabricated solar collector units is provided.

Abstract: A Nuclear Magnetic Resonance (NMR) probe including a conduit to provide a sample, a measurement region in fluid communication with the conduit, and at least one restriction element to at least partially restrict flow of the sample from the measurement region in at least one flow direction.

Abstract: A Nuclear Magnetic Resonance (NMR) probe including a temperature controlled body for providing a sample for NMR measurement such that the temperature controlled body can adapt to the sample temperature to substantially maintain the body temperature. The body encases a conduit that can contain the sample for NMR measurement. In an embodiment, the desired temperature is the operating temperature of the NMR. The body is also in communications with a temperature sensor, a heat exchanger such as a heat exchanger, and a processor that includes instructions for controlling the body temperature.

Abstract: There is disclosed an NMR probe including a body defining an internal chamber. This chamber is adapted for supporting a vacuum and the body is of a non-magnetic material. A conduit extends through the chamber in the body. The conduit has a first portion in communication with second portions, the first portion being intermediate the second portions, with the first and second portions of non-magnetic materials with substantially equal thermal expansion coefficients. An RF coil is positioned along at least a substantial portion of the first conduit portion. It is preferred that this device also include a field or frequency lock unit in the chamber, as well as a getter, to allow for degassing in the chamber to maintain the preferred high pressure vacuum. A method of using this NMR probe for NMR analysis is also disclosed.
