Helium flow cryostat

Temperature min: 2K

can be operated with 6 degrees of freedom

possibility to adapt entrance and exit window as required by experiment

sample holder: max diam = 22 mm

temperature sensor = Cernox thermometer

cool down time: 2 min to reach 4K (once He is flowing into the cryostat !)

warming up without heater: 12h if operated at T< 30 K and using intrinsic warmup (stop He-flow, no external heating)

warming up with heater: 1.5 - 2.5 h depending on operation temperature and nitrogen flushing
