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…
Carbon cluster diagnostics-II: ExB velocity filter for large carbon clusters
Shoaib Ahmad, B. Ahmad, A. Qayyum +1
An ExB velocity filter is described that has been used for the detection and diagnostics of large carbon clusters Cm (where m is up to ten thousand). The velocity and momentum anal…
Carbon cluster diagnostics-III: Direct Recoil Spectroscopy (DRS) versus ExB Velocity Analysis
Shoaib Ahmad, S. A. Janjua, M. Ahmad +3
A comparative study is being reported on the identification of heavy carbon clusters using two different techniques namely the Direct Recoil Spectroscopy (DRS) and velocity spectro…
Evolution of clusters in energetic heavy ion bombarded amorphous graphite-II: formation and fragmentation phenomena
A. Qayyum, B. Ahmad, M. N. Akhtar +1
A study has been conducted into the mechanisms of evolution of clusters and their subsequent fragmentation under energetic heavy ion bombardment of amorphous graphite. The evolving…
Evolution of clusters in energetic heavy ion bombarded amorphous graphite-III: Energy spectra of charged clusters recoiling from Xe+ irradiations
Bashir Ahmad, Maqsood Ahmad, Shoaib Ahmad
We report on a novel technique of heavy ion induced surface modification and clustering mechanisms in amorphous graphite using Direct Recoil Spectrometry. The charged clusters eman…
Evolution of clusters in energetic heavy ion bombarded amorphous graphite
M. N. Akhtar, Bashir Ahmad, Shoaib Ahmad
Carbon clusters have been generated by a novel technique of energetic heavy ion bombardment of amorphous graphite. The evolution of clusters and their subsequent fragmentation unde…
