| titleOfInvention | Cryostat operated with liquid helium and method of operation |
| abstract | The invention relates to a cryostat operating with liquid helium, comprising: a main area (4) and a main chamber (2) of a tank area (6) containing a bath (8) of liquid helium-4 for feeding liquid helium-4 A main inlet device (12) for helium-4 and a main outlet device (14) for releasing gaseous helium-4, the main inlet device comprising a transfer line (16) extending into the main region. The cryostat is configured to operate under a continuous supply of liquid helium-4 and reduced helium-4 pressure, whereby gaseous helium-4 is pumped out through the outlet means. the main chamber comprises a baffle structure (18) disposed between the tank region and the main region, the baffle structure defining at least one flow path (20a, 20b) for gaseous helium-4, Each flow path forms a circuitous connection between the tank area and the main area. The method of operation of the cryostat includes a cooling phase followed by a stabilization phase. During the cooling phase, liquid helium-4 is supplied from an external reservoir through the main inlet device into the tank area, which is cooled by evaporation until a bath of liquid helium-4 begins to accumulate on the bottom surface of the tank area. During the stabilization phase, the bath temperature of liquid helium-4 is maintained by adjusting the inlet flow rate of liquid helium-4 and/or adjusting the rate at which gaseous helium-4 is pumped through the main outlet means, and optionally by controlled heating. |
