The Compact Linear Collider (CLIC) study for a future electron-positron collider with a centre-of-mass energy up to 3 TeV aims for an accelerating gradient of 100 MV/m. The gradient is limited by Radio Frequency (RF) breakdowns, and the luminosity requirements impose a limit on the admissible RF breakdown rate. RF testing of 12 GHz structure prototypes has shown that gradients in excess of 100 MV/m can be reached with the required breakdown rate. However at CLIC, the structures will be operated with significant beamloading, modifying the field distribution inside. The effect of the beam-loading must be well understood but has not been previously measured. The commissioning and operation of an experiment to measure the effect of beam-loading on breakdown rate and the measurement results are presented.
