Carbon cluster diagnostics-III: Direct Recoil Spectroscopy (DRS) versus ExB Velocity Analysis

TL;DR

This paper compares two techniques, Direct Recoil Spectroscopy and ExB velocity analysis, for identifying heavy carbon clusters formed under ion bombardment or regenerative sooting discharges.

Contribution

It provides a direct comparison of DRS and ExB velocity analysis methods for heavy carbon cluster identification in different formation environments.

Findings

Both techniques successfully identify heavy carbon clusters.

The study highlights the advantages and limitations of each method.

Results improve understanding of cluster formation and detection methods.

Abstract

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 spectrometry using a Wien ExB velocity filter. In both the techniques carbon clusters are formed in situ either under energetic heavy ion bombardment of graphite surfaces for which DRS is employed or these are emitted from the regenerative sooting discharges and analyzed using ExB velocity analysis.
