Cryogenic Microscope System AttoAFM-I



The systems is a universal microscopic complex for surfaces, nanostructures and nanocomposite materials investigations at low temperature (up to helium) and strong magnetic fields. The systems accomplished as «ready to use», allows to conduct unique researches of elastic, dielectric magnetic and superconducting properties of nanocomposite materials.

  • Independent system for low temperature physical experiment. Cryostat with closed-loop cycle, low vibration, cooling power >350 mW, 4,2 K
  • Superconducting magnet 9 Тл, 4,2 K for cryostat with diameter 150mm, inner diameter 52cm. Gear for mounting the magnet. Power supply magnet 60A.
  • System for temperature adjustment, two channel controller.
  • Cryogen scanning atomic microscope for remote interferometric measurements with low noises at low temperatures attoAFM I. AFM microscope with vacuum tube (diameter 50,8 mm), AFM module for microscope, consisting of titanium cover, 5 additional AFM tips, one additional wave guide, ARC box with power supply (up to 5 systems) built-in 19’’ rack, ARC100-635 laser detector module for attoCube. Fotodetector 320-1060 nm. ANPx101/LT and ANPz101/LT – x- and z- positioners made of titanium, ultra strong for high pressure and low temperature.
