  The Radio Frequency (RF) design of Drift Tube Linac (DTL) of the European Spallation Source, ESS, has been defined in order to satisfy the accelerating field requirements of beam dynamic studies and to reduce peak field levels in the critical areas. The electro-magnetic field is stabilized with post-couplers. The cells geometries of the DTL are optimized to accommodate permanent magnet quadrupoles (PMQ), to get maximum shunt impedance, to meet the Moretti criterion at the low energy part and to facilitate the mechanical construction.
