Off-axis beam dynamics in rf-gun-based electron photoinjectors

Off-axis beam dynamics in rf-gun-based electron photoinjectors

The need to operate an rf-gun-based electron photoinjector with a beam emitted away from the cathode center can occur under various circumstances. First, in some cases the cathode can be affected by ion back-bombardment that progressively reduces the quantum efficiency (QE) in its center, making off...
