CLUSTER SIZE MEASUREMENT INSTRUMENT AND METHOD FOR CLUSTER ION BEAM DIAGNOSTIC |
摘要 |
A detector apparatus and its use for cluster ion beam diagnostics are described. The detector has a faraday cup (210) with a conductance path to a gas pressure detector (224) and a conductance to the detector exit (248). The detector acquires ion current, which is a measure of the ion beam flux, and also acquires mass flux, through a pressure measurement. The pressure measurement responds to the mass of dissociated gas clusters and is combined with information about instantaneous ion current to estimate mean gas cluster ion size N.
