Abstract

The European Spallation Source (ESS) is an intergovernmental
project building amultidisciplinary research laboratory
based upon the worlds most powerful neutron source.
The main facility will be built in Lund, Sweden. Construction
is expected to start around 2013 and the first neutrons
will be produced in 2019. The ESS linac will deliver 5
MW of power to the target at 2.5 GeV, with a nominal current
of 50 mA. The 120 high beta elliptical cavities, which
operate at a frequency of 704 MHz and accelerate protons
from 600 MeV to 2.5 GeV, account for more than half of
the total number of RF cavities in the ESS linac and three
quarters of the total beam power needed. Because of the
large number of RF power sources and the high power level
needed, all the design and development efforts for the RF
power source have so far been focused on this part of the
accelerator. The design and development status of the RF
power source is reported in this paper with emphasis on
reliability, maintainability, safety, power efficiency, investment
cost and production capacity.
