RF Studies at Fermilab MuCool Test Area Open
The accelerating gradient in a RF cavity is limited by many factors such as the surface material properties, RF frequency, the external magnetic field and the gas pressure inside the cavity. In the MuCool Program, RF cavities are studied w…

An integrated approach to understanding RF vacuum arcs Open
Although used in the design and costing of large projects such as linear colliders and fusion tokamaks, the theory of vacuum arcs and gradient limits is not well understood. Almost 120 years after the isolation of vacuum arcs, the exact me…

Mitigation of corona discharge is fundamental problem that was formulated by Lord Kelvin in 1911 but has not yet received a proper technical solution.On HVAC transmission lines up to 30% of the total electric power losses accounted for cor…

A General Model of Vacuum Arcs in Linacs Open
We are developing a general model of breakdown and gradient limits that applies to accelerators, along with other high field applications such as power grids and laser ablation. Our recent efforts have considered failure modes of integrate…

We explore the reasons why there seems to be no common model for vacuum arcs, in spite of the importance of the field and the level of effort expended over more than one hundred years.
