✦ Synopsis

The cryostat is charactertzed by the fact that the outer dewar vessel has no addfftonal containers to be filled with coohng hqulds (N2, Ne, H~) The requtred coohng of the radlabon screens is effected by means of narrow gaps filled wffh the evaporating hehum gas eRher from vessels rifled wtth coohng hqulds or from heat exchangers utthzmg the enthalpy of the evaporated hehum. The acceptable heat transfer between the current leads and the coohng vessels or the heat exchangers, respecbvely, is ensured by newly developed electrtcafly insulating heat contacts Detads of the quanbbes of coohng hqulds required for the operabon of the cryostat wtth a superconducting solenoid are presented The durabons necessary for coohng down the solenoid m several coohng baths, as well as subsequent to a quench of the superconducting solenoid, are spectfied

cryostats for use with superconducting solenoids have been described In literature 1,2,3 Other cryostats are commercially available from at least 6 compames Such cryostats are comparable in several respects 4 216 CRYOGENICS
