The ever-growing demand for higher RF gradients has considerably increased the risk of breakdown in accelerating structures. Field emission is the most common form of RF breakdown that generates free electrons capable of inflicting irreversible damages on the RF surface. This paper presents a simulation study to understand the effects of defects on local fields and behaviour of field emitted electrons in an RF cavity.
