Janis VTI SuperVaritemp - Variable Temperature Liquid Helium Refrigerator

Types of analysis: Electrical measurements across a wide range of temperatures and magnetic fields

Sample size (mm):

Min: -

Max: Up to 80 mm in diameter

Temperature:

Min: 1.4° K

Max: 300° K

Magnetic field (T):

Min: -8 T

Max: 3 T
Time required to cool the sample: About 40 min (system already cold) - warm-up in 1 h 30

Measurements: DC and microwave measurements

Specific features:

Uses liquid helium
2 high-frequency AC lines (40 GHz) and up to 24 DC electrical lines
4-channel SMU (Keysight)

What makes it unique?: The sample space at the center of the superconducting coil is larger than that of a conventional cryostat
