Apparatus for providing a cryogenic gaseous environment (300). A chamber (320) for containing the cryogenic gaseous environment is immersed in liquid coolant (306) to effectively cool the interior chamber, during which time gas boiled off the coolant is allowed to escape. Gas is then either injected into or allowed to accumulate in the chamber, such that liquid coolant is forced out of the chamber under hydrostatic pressure, whether through an open under port (322) of the chamber of through a standpipe (324). The interior of the chamber then provides a gaseous environment at cryogenic temperatures.
Appareil pour fournir un environnement gazeux cryogénique (300). Une chambre (320) contenant l'environnement gazeux cryogénique est immergée dans le réfrigérant liquide (306) pour refroidir de manière efficace la chambre intérieure temps pendant le quel le gaz porte à ébullition le réfrigérant, peut s'échapper. Le gaz est alors soit injecté soit peut s'accumuler dans la chambre, de sorte que le liquide réfrigérant est expulsé de la chambre sous pression hydrostatique soit à travers un orifice d'ouverture (322) de la chambre d'un tuyau vertical (324). L'intérieur de la chambre fournit un environnement gazeux à des températures cryogéniques.
