1. Secondary Emission Update
Slade J., Igor V., Alex Z.

2. Samples S1 and S1W (Al2O3)
Each scan takes 4min 20s with 30s between scans
Comparable yield to Arradiance samples
Slight decrease in yield over time is observed

3. Samples S5 and S5W (MgO)
MgO samples show higher yield than Al2O3 samples
However, I don’t know what thicknesses these samples are, so no direct comparison can be made… yet.
Increase in yield over time is observed

4. Conclusions The decrease/increase in yield for Al2O3/MgO is puzzling
These two samples are great candidates for high dose electron exposure
While the effect is smaller for low energy primaries, it still could be useful knowledge
