The PI has developed an H(2)+ gaseous field ion source that             produces a highly columnated ion beam of high angular current density           and low energy spread.  The PI proposes to extend the gaseous field ion         source to several other ion species using different gases.  The                 characteristics will be used to determine the required conditions of            temperture, gas pressure, fields, etc. for gaseous sources using helium,        the rare gases, 0(2), N(2), and some gaseous hydride, e.g. silane               (SiH(4)), phosphine (PH(3)), Arsine (AsH(3)) and diborane (B(2)H(6))            will be investigated.
