Sammanfattning
The European Spallation Source (ESS) is a planned neutron
source to be built in Lund, Sweden, which is planned
to produce the first neutrons in 2019. It will have an average
beam power at the target of 5 MW, an average current
along the linac of 50 mA, and a pulse repetition rate and
length of 20 Hz and 2.86 ms, respectively. The linac will
have around 200 LLRF stations employed to control a variety
of RF cavities such as RFQ, DTL, spoke and elliptical
superconducting cavities. The challenges on LLRF systems
are mainly the high demands on energy efficiency on
all parts of the facility, an operational goal of 95% availability
of the facility and a comparably short time from
start of final design to commissioning. Running with long
pulses, high current and spoke cavities also brings new
challenges on LLRF design. In this paper we will describe
the consequences these challenges have on the LLRF system,
and the proposed solutions and development projects
that have started in order to reach these demands.
