Transition from the C3-dominated discharge to the sooting plasma
Shoaib Ahmad, Bashir Ahmad, Tasneem Riffat
Mass spectrometry and photoemission spectroscopy of a graphite hollow cathode source identify the parameters of the transition from the C(3) dominated discharge to the sooting plas…
Regenerative Soot-VIII: Sputtering and formation of C1 and C2
Shoaib Ahmad, A. Qayyum, M. N. Akhtar +1
Photoemission spectroscopy of the regenerative soot in neon's glow discharge plasma reveals the contributions from the sputtered atomic and molecular carbon species. We present the…
Regenerative Soot: A cusp field, graphite hollow cathode, carbon cluster ion source
Shoaib Ahmad, Tasneem Riffat
An all carbon hollow cathode ion source with a specially designed cusp magnetic field Bz as a function of radius and theta is described. Velocity spectra from this source has shown…
Evolution of clusters in energetic heavy ion bombarded amorphous graphite-III: Photo-emission and velocity analysis of sputtered carbon clusters
A. Qayyum, M. N. Akhtar, T. Riffat +1
Diagnostics of the carbon atoms, ions, and clusters sputtered from a graphite surface under 10 keV Xe ion bombardments reveals the presence of neutral carbon clusters and positivel…
