ESS NORMAL CONDUCTING LINAC STATUS AND PLANS

Efficient and low loss beam acceleration in the European Spallation Source (ESS) linear accelerator (linac) gives rise to specific technical challenges in the normal conducting (nc) section. The nc linac creates high current proton beams, produces the macro and micro structures (formation of the pulse and bunches respectively) of the beam and accelerates the latter up to 90MeV before injection in the supercon-ducting (sc) linac. Design and construction of the different components of the nc linac are part of a broad collaboration involving experts of various labs in Europe. Beam commis-sioning of the warm linac in the ESS tunnel is foreseen at the beginning of 2019
