September 21st:

-Scanning graphite on tape -exposed to alpha source for 1 hour

-9-21-11AA -set point: 50.0 nA -gains: 9 -slope: -4 x

-9-21-11AB -set point: 50.0 nA -gains: 9 -slope: -8 x

-9-21-11AC -set point: 50.0 nA -gains: 9 -slope: -8 x

-9-21-11AE -set point: 50.0 nA -gains: 9 -slope: -8 x

September 22nd: -scanning Au(III) half-exposed to beta source (scanning exposed side) -took a long time to approach, approx. 30 min. -possibly due to surface disruptions from bombardment -tip wasn't the best- at times it had signs of being a triple tip

all images: -set point: 50.0 nA -gains: 9 -slope: 0 x
