	In order to evaluate the energy deposition and radiation issues concerning the ESS accelerator, a FLUKA model of the machine has been created. The geometry of the superconducting beam line is built according to the machine optics, described in the TraceWin file and the CATIA drawings of the beam elements, using the LineBuilder tool developed at CERN. The objective is to create a flexible FLUKA model that is able to be adapted to the optimization of the optics, design modifications and machine integration constraints. Preliminary results are also presented.

THPF078	Effect of the Field Maps on the Beam Dynamics of the ESS Drift Tube Linac	3864

	In the beam dynamic design and modelling of the European Spallation Source (ESS) Drift Tube Linac (DTL) simplified models have been used for the focusing and accelerating structures. Since the high current requires precise control of the beam to minimise the losses it is useful to analyse the beam dynamics by using accurate field maps of the focusing and accelerating structures. In this paper the effects of the 3D-field maps on the beam dynamics of the ESS DTL are presented.

	The European Spallation Source will offer an unprecedented beam power for spallation sources of 5 MW. The accelerator will deliver a proton beam of 62.5 mA peak current and 2.0 GeV onto the spallation target. Since the technical design report (TDR) was published in 2013, work has continued to further optimize the accelerator design. We report on the advancements in lattice design optimizations after the TDR to improve performance and flexibility, and reduce cost of the ESS accelerator.

The possibility to pulse the linac at higher frequency to deliver, in parallel with the spallation neutron production, a very intense, cost effective, high performance neutrino beam. Short pulses on the target require an accumulator ring. The optimization of the accumulator lattice to store these high intensity beams from the linac (1.1x10¹⁵ protons per pulse) has to take into account the space available on the ESS site, transport of H⁻ beams (charge exchange injection), radiation and shielding needs. Space must be available in the ring for collimation and an RF system for the extraction gap and loss control. We present the status of the accumulator for ESS neutrino facility.
