摘要： A scanning probe microscope of the present disclosure includes: a room-temperature bore superconducting magnet including a liquid helium-consumption free closed-cycle cooling system, a superconducting magnet, and a chamber having a room-temperature bore; and a scanning probe microscope including a scanning head, a vacuum chamber, and a vibration isolation platform; and a computer control system. The room-temperature bore superconducting magnet is cooled by the cryogen-free closed-cycle cooling system which eliminates the dependence on liquid helium for high magnetic field operation. There is no physical contact between the scanning probe microscope and the superconducting magnet connected to the closed-cycle cooling system. The scanning probe microscope can achieve atomic-scale spatial resolution. The temperature of the scanning probe microscope is not restricted by the low temperature conditions for operation of the superconducting magnet. The scanning probe microscope and the vacuum chamber can achieve high-temperature baking independent of the superconducting magnet for ultra-high vacuum conditions.

摘要： Methods and systems are provided for a sealing system for a dynamic nuclear polarization (DNP) system. In one embodiment, a system comprises: a reservoir including an inlet opening; an outer tube; and a tapered seal shaped to seal against the inlet opening and the outer tube, the tapered seal including: a first section removably coupleable to a second section; a through-hole formed by a first plurality of inner surfaces of both the first section and the second section, the through-hole shaped to encircle the outer tube; and a vacuum channel extending through, from an outer surface to an inner surface of the first plurality of inner surfaces, one of the first section and second section. In this way, the tapered seal may be coupled around the fluid passage without inserting a tip of the fluid passage through the through-hole of the tapered seal, thereby maintaining a sterility of the system.

摘要： A cooling device (20) has a cryostat (23) and a cold head (1), in particular, the cold head (1) of a pulse tube cooler. The cryostat (23) has a vacuum container (4) with a vacuum container wall (4a), wherein the vacuum container wall (4a) seals off a vacuum inside the vacuum container (4) from the environment. A flexible sealing section (6) connects the vacuum container wall (4a) directly or indirectly to the room temperature part (1a) of the cold head (1). The flexible sealing section (6) seals off the inside of the cryocontainer (2) from the environment. The cooling device further reduces mechanical coupling between the cold head and the cryostat, in particular, in order to enable performance of NMR measurements with fewer disturbances due to external vibrations.

摘要： A superconducting magnetic arrangement includes a magnetic coil unit. The magnetic coil unit includes a number of superconducting magnetic coils and a cryostat with an insulating vessel for cooling the magnetic coil unit. The magnetic coil unit is arranged in a vacuum in the insulating vessel. The magnetic coil unit is held in the interior of the insulating vessel by a maximum of six longitudinal bearing elements that each extend between the magnetic coil unit and the insulating vessel such that a rotary movement and a translatory movement of the magnetic coil unit relative to the insulating vessel is restrained by the bearing elements.

摘要： A gas-flow cryostat adapted for dynamic temperature regulation using a fluid level sensor; the cryostat further including one or more heaters coupled to various components of the cryostat. As fluid evaporates from a liquid cryogen evaporation reservoir within the cryostat, the fluid level sensor and a feedback control unit are adapted to monitor and dynamically control the level of evaporating cryogen by regulating the heaters. Accordingly, the cryostat is adapted to dynamically control temperature about a specimen region within the cryostat. The cryostat can be used in various applications, including analytical laboratory equipment for measuring various physical properties of samples. Temperature sensors are further incorporated for added control and optimization of the cryostat.

摘要： A method is provided for precooling a cryostat having a hollow cold head turret into which a neck tube protrudes and connects an object to be cooled to the exterior of the cryostat, wherein a cold head having a cold head stage for cooling a cryogenic working medium may be introduced into the neck tube. During a condensation operation the cryogenic working medium flows through a heat pipe into an evaporator chamber which is thermally conductively connected to the object to be cooled. During a precooling phase a precisely fitting, thermally conductive short circuit block is inserted through the neck tube into the heat pipe to provide thermal conduction between the object to be cooled and a cooling device The short circuit block is removed from the heat pipe after the target temperature is reached, and heat is subsequently transmitted through the heat pipe during a condensation operation.
