摘要： A cryogenic cooling system is provided having a vessel, the vessel comprising extending along a longitudinal axis and configured to receive a sample probe movable along the longitudinal axis. One or more cooling members are thermally coupled to the vessel so as to produce a thermal gradient along the longitudinal axis of the vessel. A vent extends along the outside of the vessel and is configured to provide a pathway for a flow of gas from an inlet of the vent to an outlet of the vent. The inlet is in gaseous communication with the inside of the vessel and the outlet is in gaseous communication an environment external to the vessel. The inlet is arranged at a position along the vessel configured to obtain a temperature below 63 kelvin during operation of the one or more cooling members, and the outlet is arranged at a position configured to maintain a temperature above 273 kelvin when the outlet has a temperature below 63 kelvin. The vent further comprises a pressure relief element configured to open and close said pathway in dependence on the pressure within the vessel such that, when the pressure of a gas inside the vessel exceeds a safety threshold, the pressure relief element is opened so as to enable a flow of said gas from the inside of the vessel to the environment external to the vessel.

摘要： Techniques facilitating low thermal conductivity support systems within cryogenic environments are provided. In one example, a cryostat can comprise a support rod and a washer. The support rod can couple first and second thermal stages of the cryostat. The washer can intervene between the support rod and the first thermal stage. The washer can thermally isolate the support rod and the first thermal stage.

摘要： A device intended for cooling an object being moved within a cryostat comprises a heat transfer section forming a contact surface for said object and means for fastening the heat transfer section to a cooling structure in such a way that said contact surface remains free. The device comprises a spring section which is separate from said heat transfer section and which is arranged to exert on the heat transfer section a spring force pushing said contact surface in a direction in which it is intended to contact said object.

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.
