3. Insulation breakdown by microparticles
This section presents the simplest proposed approach to explaining the breakdown of vacuum insulation. Although this approach remains simplistic, it is often used and has a pedagogical character. It is explained below.
3.1 Cranberg theory
The explanation put forward by Cranberg to explain vacuum breakdown was the presence of microparticles (projections of micron-sized material – such as dust, polishing or cleaning residues, etc.) which are weakly bound to the surface (by Van der Waals-type forces). By applying a strong electric field, the charged...
