Cooling Stages

• 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
