4. 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 do 1)Kelvin probe work function – cleand and dirty surfaces 2)Mg & Be on baked surface (with carbon) 3)Mobility of carbon 4)Best way of cleaning surfaces 1)Oxidation/Reduction, Atomic Hydrogen, Nitric oxide 3)Extend surface trap studies – deposition and cleaning 1)Deposit materials onto surface trap 1)Al, Nb, Ag, Cu, Ru, Re, TiN, NbN, Graphene
