A model of rf breakdown arcs

Insepov, Z.; Bross, A.; Qian, Z.; Norem, J.; Huang, D.; Veitzer, S.; Torun, Y. (Fermilab, 2008)

This paper presents a rst iteration of a model that attempts to describe all aspects of breakdown in rf cavities and provides some estimates of the parameters and parameter ranges involved, as an aid to producing more ...
Effects of surface damage on rf cavity operation

Hassanein, A.; Insepov, Z.; Norem, J.; Moretti, A.; Qian, Z.; Bross, A.; Seidman, D. N. (Physical Review Special Topics-Accelerators and Beams, 2006)

We describe a model of damage in rf cavities and show how this damage can limit cavity operation. We first present a review of mechanisms that may or may not affect the ultimate fields that can be obtained in rf cavities, ...
The Interactions of Surface Damage on RF Cavity Operation

Norem, J.; Bross, A.; Hassanein, A.; Qian, Z.; Yoon, K. E.; Moretti, A.; Li, D. (Fermilab, 2006-06)

Studies of low frequency RF systems for muon cooling has led to a variety of new techniques for looking at dark currents, a new model of breakdown, and, ultimately, a model of RF cavity operation based on surface damage. ...
