Raith ebeam updates
The Raith ebeam is now back online. There were 2 problems associated with the tool:
1). beam drift
The drift was caused by a damaged end cap, which happened when the sample moved too close to the lens. Scratches were clearly visible on the cap.
As a reminder, for future use of Raith, please place your sample at a safe distance away from the lens. The column is optimized to work at 11mm WD. Smaller WD won't necessarily result in better resolution.
