  The ESS linac design has evolved over time and is now quite stable. Recently, there has been a focused effort on developing more detailed installation and commissioning plan, and related to this, the plans for diagnostics has also been reviewed. This paper presents the updated diagnos-tics suite. Many of diagnostics systems will be developed by in-kind partners across Europe.

  The European Spallation Source, ESS, uses a linear accelerator to bombard the tungsten target with the high intensity protons beam for producing intense beams of neutrons. The nominal average beam power of the linac is 5~MW with a peak beam power at target of 125~MW. This paper focuses on the beam dynamics design of the ESS linac and the diagnostics elements used for the tuning of the lattice and matching between sections.

  The European Spallation Source front end will deliver a 62.5 mA beam current of 2.8 ms duration at 352 MHz to the downstream linac, which in turn will produce a 5 MW proton beam onto the target. Such unprecedented beam power requires a high quality beam with accurate and stable beam parameters in order to assure low beam losses and safe transport through the linac. In this paper we present advanced tuning methods for the low energy beam transport and the radio frequency quadrupole.

  The commissioning and operations planning for the European Spallation Source is currently being defined. It is foreseen that the ESS will begin to deliver beam on target by mid 2019, something which is urging a well structured and thought through plan both for commissioning and operations. In this paper we will discuss the plans for beam physics operational software, priorities and software services needed during the different stages of beam commissioning.

  The construction of the European Spallation Source, ESS, started in summer 2014. At the site in Lund, the accelerator tunnel will be completed at the time of IPAC16, while prototyping and manufacturing or prepara-tions for manpower contributions are going on in more 23 laboratories distributed over the 12 European countries collaborating on the accelerator project. Major technical milestones have been reached include the testing of su-perconducting cavity prototypes of two families to values above design gradients, the first ESS modulator has been tested to 90 kV and the first klystron prototype has been received in April 2016. Equally important developments are taking place at many partner laboratories. The presen-tation will summarize the status of the ESS accelerator project by the time of IPAC16..
