RF coupler plarform (CEA)
The platform is powered by two 704.4MHz RF lines (one from the CPI klystron and the other from the Thales klystron) and is equipped with an oven for baking the couplers.
- RF: generation of standing and travelling waves, measurement of reflected and incident powers thanks to two bidirectional couplers placed upstream and downstream of the couplers to be tested,
- Test frame: a Norcan frame to place the couplers, the frame having been developed specifically for the ESS couplers with a mechanical system to easily mount the doorknobs on the couplers,
- Vacuum: A pumping unit,
- Possibility to program temperature profiles and to perform a nitrogen scan in the oven.
Power couplers infrastructure (CNRS)
Clean rooms are available for cleaning, assembling, preparing and RF conditioning of power couplers. The existent infrastructures and equipment are adapted for mass production at a rate up to 8–10 couplers per week.
- First clean room (ISO4 and ISO6),
- Second clean room ISO5,
- Power sources:
- 1 RF power source 1.3 GHz, 2MW with variable repetition rate (2–4Hz) with the required waveguides, circulators, spreaders, loads…
- 1 RF power source 1.3 GHz, 5MW with variable repetition rate (1–10 Hz) with the required waveguides, circulators, spreaders, loads
