- Immediately note: Order of magnitude less current for stainless steel
- But, rotating the sample holder to ~300 deg = x10 current compared to 320 deg
- Ie: More current when sample surface is not perpendicular to axis of gun
- ??? Beam deflected horizontally by Earth's B field?
- Put to 320 deg; use same orientation as for Si
- Curve looks "unfocused"; no plateau
