5-axis High Power sub-Kelvin Helium-3 Cryostat for ARPES

January 2014

After successfully developing the world’s first 4-axis high power sub-Kelvin He-3 cryostat for Angle-Resolved Photoemission Spectroscopy (ARPES) application in 2008, Janis Research’s ultra low temperature (ULT) group is proud to announce a 5-axis high power sub-K He-3 cryostat for ARPES application has been successfully tested recently, and it has the following performance specifications:

Five (5) degree of freedom: X-motion, Y-motion, Z-motion, Phi (azimuthal), and theta (tilt)

Base temperature on the rotating/tilting sample holder: 840mK

Azimuthal rotation range: 195 degree

Tilting range: +/- 30 degrees

Cooling power with phi =0 and theta = 0: see plot

UHV compatible

Baking temperature: 90 degree C
