-- 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
: 840mKAzimuthal rotation range
: 195 degreeTilting range
: +/- 30 degreesCooling power with phi =0 and theta = 0:
