The system reached base temperatures of below 300 mK with 80 hour holding time (longer holding time can be reached with additions He-3 gas) while pumping on the 1 K pot;
Special noise reduce is installed inside the 1 K pot to suppress the acoustic noise;
With Janis superior design, the user can even stop pumping the 1 K pot to completely eliminate the noise from the 1 K pot and operate the He-3 cryostat below 320 mK with 40 hour holding time (longer holding time can be reached with additions He-3 gas);
The He-3 insert has a central line-of-sight with diameter up to 1.25” for sample loading, with a UHV compatible gate valve located at the top for user’s sample change;
Specially designed rigid support on the He-3 pot to minimize the vibrations;
Mechanical heat switch for fast pre-cooling of He-3 pot;
4.2 K radiation shutter and 1.5 K radiation shutter;
The He-3 insert is designed to be compatible to all kinds of superconducting magnet, such as solenoid, vector magnets. etc.;
Other features such as sliding seal, low and/or high frequency wiring/coaxial cables for the user, fiber optics, etc., are available;
