The EMS 25 Cooling Stage for ESEM, VP, EP, and SEM
The EMS25X is a Peltier Driven Cooling Stage for SEM primarily VP & ESEM. It allows the stage
to be cooled to sub zero temperatures for samples, which may be sensitive at ambient
temperature, subject to beam damage, or may be sublime at ambient temperatures.
The Cooling Stage is located on the existing SEM Stage, and is designed to accept the standard
range of stubs used with the SEM.
The Cooling Stage on the SEM Stage has secondary cooling via a liquid cooling circuit, through
a ‘spare’ access port on the SEM, to the external heat exchanger unit, which is fully vacuum,
isolated from the SEM chamber. This arrangement allows the majority of the x,y,z and tilt
features to be maintained to an effective operating level.
The system is self-contained and employs a small power supply and temperature control
system, the unit is supplied from standard supply socket.
The major parts of the system can be left in situ, and the Cooling Stage is very easily removed when reverting to ‘normal’ use.
