Abstract

We tested the prototype DQW cavity in GERSEMI vertical test stand in FREIA. The performance met the specification, and our experimental procedure and infrastructure are qualified for testing crab cavities in the HL-LHC project. This was the critical milestone in the project and it also opens a new opportunity for testing superconducting cavities in FREIA.
