The development of carbon-based sensors for the measurement of atomic oxygen
The development of carbon-based sensors for the measurement of atomic oxygen
This paper describes preliminary results of atomic oxygen (AO) exposures on a variety of carbon-based films and assesses their suitability for sensing atomic oxygen in low Earth orbit (LEO), by means of actinometry (measurement of film electrical resistance). Atomic oxygen exposures were carried out using the ESA-ESTEC ATOX pulsed atomic oxygen facility to energies of 5ev (~8km/s) with fluences of up to 7.9 x10^19 atoms/cm2. The carbon types exposed were electron beam (e-beam) vacuum evaporated and d.c magnetron sputtered carbon. Raman and X-ray photoelectron spectroscopy techniques have so far been used to characterise the carbon.

Abstract
This paper describes preliminary results of atomic oxygen (AO) exposures on a variety of carbon-based films and assesses their suitability for sensing atomic oxygen in low Earth orbit (LEO), by means of actinometry (measurement of film electrical resistance). Atomic oxygen exposures were carried out using the ESA-ESTEC ATOX pulsed atomic oxygen facility to energies of 5ev (~8km/s) with fluences of up to 7.9 x10^19 atoms/cm2. The carbon types exposed were electron beam (e-beam) vacuum evaporated and d.c magnetron sputtered carbon. Raman and X-ray photoelectron spectroscopy techniques have so far been used to characterise the carbon.
