Over the past 15 years, Hope College has been creating hydrogen and helium ion beams with an Alphatross™ ion source and Pelletron™ tandem Van de Graaff accelerator. The manufacturer stated the possibility of creating nitrogen ions in this source, but Hope College has not, up until now, attempted to do so. By mixing approximately 1% nitrogen into hydrogen source gas, nitrogen (N-) and imidogen (NH-) ions were created and accelerated through the tandem accelerator. These ion beams were directed and isolated by a dipole bending magnet for identification. Alternate beams such as these open up new possibilities for future experiments such as nitrogen implantation.
