Special Hybrid Dewar for
Efficient Operation with a Superconducting Magnet
April 2007
Janis Research is pleased to announce that it is offering a special hybrid
nonmagnetic stainless steel cryocooler shielded
liquid helium research dewar for efficient operation with a superconducting
magnet. The cryostat is supplied with three neck inserts. The first
insert allows magnet charging and helium refilling with the leads in place.
The second insert has a baffle assembly for the lowest heat load. The
third insert will allow helium refilling with a baffle assembly in place.
The system has a static loss rate of less than 5 ml of liquid helium per hour
and an effective hold time of four months with the magnet in persistent mode.
The cryostat offers a low profile and a horizontal room temperature bore with
full access ports to the cold head and to the instrumentation wiring for easy
maintenance and cold head replacement.
Please contact Janis for more details.
