I'd assume that the inputs to the system are far, far more than 10 kW continuously. I just ordered 4 servo motors for a modest-sized industrial machine that moves steel plates around to assemble construction equipment, each one is capable of about 8 kW.

I'd be unsurprised if the particle accelerator complex generated waste heat on the order of 5 megawatts to generate a particle stream with an energy of 10 kilowatts. That's 0.2% efficient, pretty good!

I bet just running the ceiling lights across the complex uses a lot more than 10 kW...
