Cooling Stages

Helium and liquid nitrogen stages to monitor cryogenic or temperature dependent studies to better understand your electrical and electronic materials.
  • Beam sensitive materials are stabilized under high beam currents
  • Low-temperature phases can be studied
  • Enhanced imaging and spectroscopy, especially for cathodoluminescence (CL)

Liquid nitrogen cooling stages C1001, C1002, C1003
  • Simple installation/removal allows use of standard SEM stage
  • Stages cooled to less than -185 °C by nitrogen gas
  • Efficient thermal design ensures rapid cool down and stable temperatures
  • Accurate control through integral heater and temperature sensor
  • External liquid nitrogen heat exchanger removes vibration due to boiling of LN2
  • Higher upper-temperature options for more flexibility in experiments
Liquid helium cooling stages CF302, CF302M
  • Specially designed low drift and vibration, while minimizing liquid helium consumption
  • Complete replacement SEM stage and door assembly with X, Y, Z axis manual micrometers
  • CF302M is a helium-cooled stage module that attaches onto SEM goniometer, and requires more care than the CF302
  • Complete system includes flexible transfer tube storage vessel, top fitting with bladder and valve, gas flow controller, gas flow pump, and digital temperature controller
  • Optional radiation shield can be included depending on intended use and configuration 
Dual fuel option
  • Allows liquid helium cold stages to be operated with either helium or nitrogen
  • Functions by forcing cold nitrogen gas through the circuit similar to the successful C1002 product 
Accessories—Anti-contaminators
  • Accessories include C1005, C1006, or C1007 anti-contaminators
