Removal of spacecraft-surface particulate contaminants by simulated micrometeoroid impacts [PDF]

open access: yes
A series of hypervelocity impacts has been conducted in an exploding lithium-wire accelerator to examine with a far-field holographic system the removal of particulate contaminants from external spacecraft surfaces subjected to micrometeoroid bombardment.

Particulate Measurement Methods

open access: yes, 2003
The presence of soot is essential in some processes: it is the product in carbon black; it provides the source of light radiation in pyrotechnic and pyrophoric flares; and is the dominant source of radiant heat transfer in boilers and furnaces. However, it is also an undesirable product in many combustion processes where it is expelled with the exhaust,
