In order to reach 5 MW proton beam power, the ESS linac will be powered by 155 RF transmitters using different technologies. Most of these transmitters will use klystrons as amplifiers, and more precisely six 3 MW, 352 MHz klystrons in the normal conducting linac, and 120 1.5 MW, 704 MHz klystrons in the superconducting linac.
The talk will give an overview of the ESS klystron-based systems, with focus on the experience gained during installation, testing and initial operation; some of the issues faced during the commissioning of the power stations will be discussed.
Possible solutions to increase the operational efficiency of the systems will be presented, with results from initial tests.”
