Kneisel, Peter

Superconducting niobium cavities for particle accelerator application are performing nowadays better than ever and a series of procedures have been established--if applied properly--which will result in multi-cell cavity gradients of up to E{sub acc} = 35 MV/m, the design goal for the International Linear Collider (ILC). In several cases gradients above 40 MV/m have been measured in single cell tests. These gradients are close to or at the critical magnetic field value for niobium--at least what is believed to be the fundamental limitation of the material. However, there are still some open questions, whether the value for the superheated magnetic field of {approx} 180 mT is the final answer.
