Paper Abstract

The adhesion force holding particles to a representative engineering optical surface has been investigated. This study addresses the measurement of the removal force from technologically clean surfaces (as opposed to atomically clean). The determination of the adhesion force was by a centrifuge technique, spanning several thousand g's. Particle removal diagnostics were performed optically by measuring residual populations at various g levels. Particles between 10 and 1000 micrometers and various compositions were tested. The results of the experiment have shown that the adhesion forces on similar particles vary immensely. This may help to explain some unexpected transfer phenomena in relatively low-g environments.
