Modeling arcs

Insepov, Z.; Norem, J.; Vetizer, S.; Mahalingam, S. (American Institute of Physics, 2011-12)

Although vacuum arcs were first identified over 110 years ago, they are not yet well understood. We have since developed a model of breakdown and gradient limits that tries to explain, in a self-consistent way: arc triggering, ...
Modeling RF breakdown arcs

Insepov, Z.; Norem, J.; Proslier, T.; Huang, D.; Mahalingam, S.; Veitzer, S. (arXiv preprint arXiv:1003.1736, 2010)

We describe breakdown in 805 MHz rf accelerator cavities in terms of a number of self-consistent mechanisms. We divide the breakdown process into three stages: (1) we model surface failure using molecular dynamics of ...

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 ...
