Microparticles in high-voltage accelerator tubes

Abstract

Microparticles with radii greater than 2 mu m have been observed in a high-voltage vacuum accelerator tube. The charge acquired by most of the particles is similar to the contact charging of a conducting sphere on a plane.

Nanoscale Characterization of Gold Colloid Monolayers: A Comparison of Four Techniques

“…[30][31][32][33][34][35][36][37][38][39][40] This approach can be problematic, particularly when the topographic information is convoluted with instrument response. 45,46 Moreover, when two approaches have been employed, they have involved different samples. This paper describes the nanoscale characterization of self-assembled, covalently bound 2-D arrays of colloidal Au particles [41][42][43][44] using AFM, FE-SEM, TEM, and NSOM.…”

Copper sample analyzed with an n-doped silicon tip using conducting probe atomic force microscopy

“…27 Thus, when the surface features become smaller than the tip apex, the shape of the latter can be observed on the acquired image. 27 Thus, when the surface features become smaller than the tip apex, the shape of the latter can be observed on the acquired image.…”
