Huge challenge for ESS Bilbao, the RF Systems are on site Courtesy of ESS Eight years ago, a team of almost 15 researchers from I’m very proud of the team ESS Bilbao made the commitment and accepted the challenge to take over the design, manufacturing and that has been involved in commissioning of allthe RF systems for the Normal this challenging project. Conducting section of the European Spallation Source (ESS) proton LINAC. During all these years, there have Thanks to all efforts and been many difficulties that they have had to face but in the end the effort and work of the whole team in coor commitments, we have dination with the industrial partners in Spain has made delivered a key part of the European it possible and most of the RF equipment is already installed at the ESS site in Lund, Sweden. This work has Spallation Source. The installation and been co-funded by European Regional Development Funds under the FEDER TRACKS project (Transmisores commissioning of the RF stations are de RF para Aceleradores basados en Klystrons y Estado Sólido). already a reality The ESS project is the world’s most powerful pulsed neutron source based on a linear accelerator or linac, Pedro González, which accelerates a proton beam of 62.5 mA current to Technological Director an energy peak of 2000 MeV. This includes a supercon and RF System ducting linac, preceded by a normal conducting section work package leader at composed of an Ion Source, an RFQ (Radio Frequency ESS Bilbao. Quadrupole), an MEBT (Medium Energy Beam Trans port, also an ESS Bilbao contribution) with three bun 6
