AuSi experiments Nov 30 12

Introduce two new samples on large-circle holders

• AS121130F - 670 C tube furnace, quenched, air, older holder no faraday hole
• AS121130D - 655 C, newer holder with FC hole

Transfer samples to carousel, look at F sample, rather low carbon, can find denuded zones, shadow zone clearly visible in Auger images near O KLL at 3 kV.

Get nice LVV Si and NVV Au at 3 kV. Record auger map images with smart sem 14 bit. Switch to 10 kV for Si KLL and Au MNN.

Need to readjust max current gun align, escecially at 3 kV.
