High Vacuum Heating Stage

Cleaner conditions, better image quality and more information at high sample temperatures

The High Vacuum Heating Stage allows for an easy workflow to heat samples up to 1100° C while preserving excellent image quality.

Understanding the properties and functions of metals and other materials in real-world conditions requires high resolution, high contrast microscopy of samples at high temperature and in a controlled environment. The High Vacuum Heating Stage meets these requirements with a unique design and an accessible workflow – it enables clean heating experiments that are controlled through the user interface of the SEM or DualBeam
instrument. With temperature logging integrated in the image
data, the High Vacuum Heating Stage allows for recording all experiment data including images and videos in one go.

The High Vacuum Heating Stage is capable of working in high vacuum conditions without significant outgassing. This provides several advantages over working in low vacuum conditions: the SEM can work over a large parameter space that includes
high beam energy, low beam energy, immersion, and in-column
secondary / backscatter electron detection, greatly improving
the achievable resolution and contrast. Operating at high speed,
the high-vacuum detectors make it easier to track transient
processes with fast image acquisition.

Moreover, high vacuum provides a cleaner environment – heated
surfaces will run a much reduced risk of reaction with oxygen or
water when there is no imaging gas to react with. This provides
more room for observing heated surfaces that would otherwise
be covered in oxide.

Finally, high vacuum operation improves the backscatter signal
that is detected in electron backscatter diffraction (EBSD)
analysis – with this stage, high quality EBSD maps can be
acquired at temperatures up to 900° C.

Covering a wide range of heating experiments while allowing
excellent image quality and easy operation, the High Vacuum
Heating Stage is an essential tool for materials scientists
studying high-temperature phenomena at the nanoscale.

Sample mounting

All samples should be placed on a silicon heating substrate.
Samples are mounted using:

  • Press clamp with round central hole of diameter: 2mm, 3mm,
    5mm, without screws (consumable)
  • Two (up to four) clamps with screws

Installation requirements and compatibility
The high vacuum heating stage is compatible with Quattro, Apreo
and Scios and occupies one port for hot/cold feedthrough.
