A cryostat for operation with liquid helium, may comprise a primary chamber with a main region and a pot region for containing a bath of liquid helium-4, primary inlet means for introducing liquid helium-4 and primary outlet means for releasing gaseous helium-4, the primary inlet means comprising a transfer line extending into the primary region. The cryostat may be configured for operation under a continuous supply of liquid helium-4 and at a reduced helium-4 pressure, whereby gaseous helium-4 is pumped off through the outlet means. The primary chamber may comprise a baffle structure arranged between the pot region and the main region, the baffle structure defining at least one flowpath for the flow of gaseous helium-4, each flowpath forming a detoured connection between the pot region and the main region.
