Description

The dynamics of dislocation activity under intense electric fields has been proposed as a potential cause of breakdowns. In this talk, results of searches for high-frequency fluctuations in field-emitted current that could arise as a consequence of these dynamics are presented for high-gradient RF accelerating structures and pulsed DC experiments at CERN. Measurements of spatial profiles of field emission in RF structures and long-term variations will also be presented.
