SiAu dewetting expt

Play around with conditions. Si and Au LMM peaks much better for 8 kV than 3 kV. % is OK but 8 is better. Did not try above yet. Peak stronger background less.

At 8 kV hard to get signal below ~ 250 eV regardless of deflection settings.
For 8 kV 1600 V approx +36.7,51.5 octopole

On eutectic squares and blobs, AuSi silicon peak is dramatically changed in shape
Doublet 1616.5, 1609 and 1557.5, 1552.5

Pure Si more like 1617, 1598, 1577, 1559, 1543

Au core levels
4s 763
4p  643, 547
4d 353, 335
5s ~ 110
4f 84, 88
5p 57, 74
