DigiSTAR Precession Electron Diffraction
NanoMEGAS DigiSTAR: a patented precession device for TEM that acquires precession electron diffraction (PED) patterns, compatible with most TEMs.
Key features
- Precession ED
- Controls the TEM beam to acquire precession electron diffraction patterns.
- Most TEMs
- Including single and double Cs-corrected TEMs; one system can serve several TEMs in a lab.
- Beam compensation
- Keeps the probe small at all precession angles.
- Saved alignments
- For different TEMs, modes and precession angles.
- Applications
- With ASTAR orientation imaging, strain mapping, 3D diffraction tomography and 3D image tomography.
Specifications
From NanoMEGAS's product page.
| Precession half-angle | Typically up to 0.5–3° (depends on the TEM column) |
|---|---|
| Precession frequency | 1 to 1,000 Hz (column dependent) |
| Beam compensation | Reduces beam size by ×5 or more, by software |
