Stylus Trap electrode geometry• Height of stylus – 150 m• Height of ion > 50 m• Height of surface > 200 m• Width of pads @ corners
– ~ 700 m
Wire bond thickness - ~25 – 50 mAllows room for sample
Wire bond width ~ 250 mAllows lasers to come in diagonally

Contingencies• Delay of laser for measurement of Mg
1) We still have a lot of setup – optics, ionization laser setup, camera
2) We still have lots of surface science to do1) Kelvin probe work function – cleand and dirty surfaces2) Mg & Be on baked surface (with carbon)3) Mobility of carbon4) Best way of cleaning surfaces
1) Oxidation/Reduction, Atomic Hydrogen, Nitric oxide
3) Extend surface trap studies – deposition and cleaning1) Deposit materials onto surface trap
1) Al, Nb, Ag, Cu, Ru, Re, TiN, NbN, Graphene
