Fast Sample Exchange

We offer for fast sample exchange a fully automatic load-lock system with two versions for top and bottom-loading solutions. The insert movement is computer controlled and allows for an optimized pre-cooling sequence with a sample cool-down time of less than 8 hours. The load-lock mechanism comes with a smart controller that prevents accidental venting of the vacuum chamber and conflicting operation of the insert and gate valve. Loading mechanism can also be operated manually either with computer software or directly on the controller unit.

Options

Bottom-Loading Insert

The bottom-loading option has bulk of the experimental wiring on fridge and the bottom-loading sample holder mates at mixing chamber flange with the wiring. With more available space in the fridge it is possible to also have devices that require more space installed on the lines for example filters, RF amplifiers and RF circulators. Probe diameter is determined by the magnet bore while available diameters are Ø 38 mm, Ø 48 mm, Ø 58 mm and Ø 78 mm for both LD and XLD.

Typical performance specifications

• Base temperature < 20 mK
• Cooling power @ 100 mK is > 50 µW

Top-Loading Insert

The top-loading solution has all experimental wiring on the insert. Maximum insert diameter is set by the selected line-of-sight port. Available diameters for both LD and XLD are Ø 38 mm,  Ø 48 mm Ø 58 mm.  Ø 78 mm is available for XLD only. Entire system including cryostat and load-lock system has a height of approximately five metres.

Typical performance specifications

• Base temperature < 20 mK
  
• Cooling power @ 100 mK is > 50 µW
