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

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

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

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
