Low-energy linear oxygen plasma source [PDF]

Review of Scientific Instruments, 2007
A new version of a constricted plasma source is described, characterized by all metal-ceramic construction, a linear slit exit of 180mm length, and cw operation (typically 50kHz) at an average power of 1.5kW. The plasma source is here operated with oxygen gas, producing streaming plasma that contains mainly positive molecular and atomic ions, and to a ...

A reaction mechanism for oxygen plasmas

Plasma Sources Science and Technology, 2023
Abstract This work presents a reaction mechanism for oxygen plasmas, i.e. a set of reactions and corresponding rate coefficients that are validated against benchmark experiments. The kinetic scheme is validated in a DC glow discharge for gas pressures of 0.2–10 Torr and currents of 10–40 mA, using the 0D LisbOn KInetics simulation tool ...

Dry etching of single-point cutting tool made of nano-polycrystalline diamond using oxygen plasma (Shapeable cutting edge radius)

Nihon Kikai Gakkai ronbunshu, 2022
Dry etching using oxygen plasma was conducted on a single-point cutting tool made of nano-polycrystalline diamond to clarify the shapeable cutting edge radius (CER). The CER of the tool was measured by atomic force microscopy (AFM).
