A Helium Recondenser Using 4 K Pulse Tube Cryocooler
A helium recondenser using a 4 K pulse tube cryocooler (model PT405) has been developed as a solution to reduce liquid helium boil-off in the existing non-refrigerated helium dewar or helium cryostat. The condensing part of recondenser is inserted into the neck tube of the helium dewar or cryostat....

| Zusammenfassung: | A helium recondenser using a 4 K pulse tube cryocooler (model PT405) has been developed as a solution to reduce liquid helium boil-off in the existing non-refrigerated helium dewar or helium cryostat. The condensing part of recondenser is inserted into the neck tube of the helium dewar or cryostat. The helium vapor is condensed at 4.2 K and the condensed liquid flows back to the liquid helium bath. The recondenser has been experimentally tested to condense 14 liters/day of liquid helium while consuming 4.5 kW electrical power. |
