Spatial charge effects in retarding field analyzer ion measurements in a cathodic vacuum arc

The ion energy distribution (IED) obtained from a cathodic vacuum arc using a retarding field analyzer (RFA) was investigated. The spatial charge effects in the grid-collector region of the analyzer were taken into account in the RFA ion measurements. It was found that there was a decrement of colle...
