Helios 5 Hydra DualBeam – Plasma Focused Ion Beam
The Helios Hydra G5 enables milling on the millimeter length scale and is fully equipped with multiple deposition and etching chemistries.
Location: EBI room 1046B
The Helios Hydra G5 uses gas-based plasmas for milling and deposition. The advantages of using plasma is that beam currents can be much higher, leading to much faster mill rates, meaning one can spend less time milling features or mill much larger features. The Hydra enables milling on the millimeter length scale. It’s fully equipped with multiple deposition and etching chemistries, an extremely user friendly sample lift out manipulator, and state of the art EDS and EBSD attachments. These accessories enable the site specific study of structure, chemistry, and crystallography in 2D and 3D.
