Description
RF Breakdown is a critical factor driving the design and limiting the performance of high gradient RF cavities. Within these high E-field cavities, localised field enhancement effects can occur due to microscopic surface imperfections - resulting in field strength of orders of magnitude greater than the cavity's average - leading to plasma formation, material damage/degradation and field emission.
In the context of the muon collider's cooling channel, a strong external magnetic field is superimposed (2-5T) on the existing RF field, increasing the risk of RF breakdown and limiting maximum gradients.
This poster presents CST simulations, supported by investigation of secondary electron yield distributions, which can be applied to understand the role of the static magnetic field in the breakdown dynamic.
