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. ...
The problem of RF gradient limits

Norem, J.; Insepov, Z.; Huang, D.; Mahalingam, S.; Veitzer, S. (American Institute of Physics, 2010-03)

We describe breakdown in rf accelerator cavities in terms of a number of mechanisms. We divide the breakdown process into three stages: 1) we model surface failure using molecular dynamics of fracture caused by electrostatic ...
Vacuum arcs and gradient limits

Norem, J.; Moretti, A.; Insepov, Z. (Proceedings of 2011 Particle Accelerator Conference, New York, 2011)

We have been extending and refining our model of vacuum breakdown and gradient limits and describe recent developments. The model considers a large number of mechanisms, but finds that vacuum arcs can be described fairly ...
