MEASUREMENTS OF THE FIRST RF PROTOTYPE OF THE SPIRAL2 SINGLE BUNCH SELECTOR

The single bunch selector of the Spiral2 driver uses 100 Ω travelling wave electrodes driven by fast pulse generators. 2.5 kV, 1 kW feedthroughs and a vacuum chamber housing the water cooled electrodes have been designed and built. The paper reviews the whole design and reports the results of first RF and power measurements.
