2 CERN Rüdiger Schmidt Nine months at ESSpage 2 Why ESS? Why neutron scattering ? ● Neutron scattering can be applied to a range of scientific questions, in physics, chemistry, geology, biology, engineering and medicine. ● With a neutron tool kit, we can probe the structure and dynamics of materials over a wide range of length- and time-scales life science, life science soft condensed matter research, soft condensed matter research chemistry of materials, chemistry of materials energy research, energy research magnetic and electronic phenomena, magnetic and electronic phenomena engineering materials and geosciences, engineering materials and geosciences archaeology and heritage conservation, archaeology and heritage conservation fundamental and particle physics. fundamental and particle physics

14 CERN Rüdiger Schmidt Nine months at ESSpage 14 Recipe for a Spallation Source ● Accelerate many many many protons to 1 – 2 GeV Proton beam power of several MW, 1.5 * protons / second ● Send the protons to a metal (tungsten) target 1 GeV proton => about 20 Neutrons ● Slow the neutrons down to thermal energies Watch out – do not mix meV and MeV ● Send them through (curved) guides to the experiments ● Have an experiment (instrument) to use the neutrons Single-Crystal Diffractometer (TOPAZ)

22 CERN Rüdiger Schmidt Nine months at ESSpage 22 Example of a (small) target: ISIS target hall

23 CERN Rüdiger Schmidt Nine months at ESSpage 23 ESSS: some numbers ● Staff number at ESS: today about 200, expected to increase to when operating ● Start of operation (first protons on target) planned for 2019 ● Projected lifetime: 40 years ● Operation budget per year: 140 M€ ● The construction budget for ESS is 1843 M€ Accelerator:510 M€ Target station:150 M€ Infrastructure:520 M€ Controls etc.: 70 M€ N Instruments:350 M€ Others: administration, licencing, energy, … Not a typo

24 CERN Rüdiger Schmidt Nine months at ESSpage 24 ESS specific ● ESS is an emerging research laboratory with (still) very limited capacity in-house ● Collaborative projects: Work in a collaboration where the scope of the project can be set by the total capacity (distributed) of the partners ● The accelerator part of the project well suited for this as this community has a strong tradition of open collaboration (XFEL, FAIR, CERN, e.g.LINAC4, European commission framework programs such as EUCARD and TIARA, EURISOL,...) ● To keep cost down and to optimize schedule this requires that investments in required infrastructure is done at the partner with best capacity to deliver

26 CERN Rüdiger Schmidt Nine months at ESSpage 26 Transition from construction to operation ESS Operations can be divided into three distinct phases: Initial Operations Phase (2019 – 2022, 4 years) – Includes one year of activities to produce first neutrons (2019) and three years of activities to improve accelerator performance and to commission instruments (experiments by friendly users); Initial User Program Operations (2023 – 2025, 3 years) – Includes support necessary for reliable operations with public users and provides the basis for future cost sharing; and, User Program Operations (Beginning in 2026 – ) – Routine operations including the completion and commissioning of the final 22 public instruments.

27 CERN Rüdiger Schmidt Nine months at ESSpage 27 Scope contingency for 5 MW accelerator We plan for delivering a 5 MW accelerator The scope contingency for the accelerator is beam power. The purchasing of power supplies and RF sources necessary to go from 2.5 to 5 MW will be scheduled discretely. These purchases will be authorized after the financial requirements for delivering 2.5 MW of beam power are secure. Each 7 M€ reduction decrease energy by 70 MeV (=175 kW at 62.5 mA) Spokes Medium β High β DTLMEBTRFQLEBTSource HEBT & Contingency Target 2.4 m4.5 m3.6 m 40 m54 m75 m174 m 75 keV 3.6 MeV90 MeV220 MeV570 MeV2000 MeV MHz MHz Scope conting ency 100 M€ CM and RF sources Scope conting ency 100 M€ CM and RF sources

29 CERN Rüdiger Schmidt Nine months at ESSpage 29 My involvement ● Learning about sc high intensity proton linacs ● Machine Protection (..organised a PLC workshop) ● Planning ● Controls systems ● … and many activities not related to ESS

30 CERN Rüdiger Schmidt Nine months at ESSpage 30 Some of my impressions ● Exciting new project in the accelerator world Together, ESS and MAXlab will become one of the major accelerator research centres in Europe ● Working methods very different from CERN Very formal definition of requirements….. Structure of technical discussions not obvious… Very little collaboration between the two labs Surprisingly little activities related to protection of personnel yet…. ● Many challenges Building up a lab from scratch on a green field Working with outside partners to deliver most systems Building up a base with qualified personnel ● Collaboration in some areas can be of interest for both labs, ESS and CERN Interlock and protection systems Superconducting RF Others (beam losses, BLMs, diamond detectors, ….)

31 CERN Rüdiger Schmidt Nine months at ESSpage 31 Slide from Mats Lindroos

32 CERN Rüdiger Schmidt Nine months at ESSpage 32 -The first ESS annual review took place at LUND the 12 th -14 th November Present : ESS project team, 33 members of the review team organized in 7 subcommittees and 7 observers (see next slide for details) First impressions: -The review committee congratulates the ESS team and its management for the quality of the material and presentations submitted to the reviewers -The ESS is now a real project from all points of view, well shaped and well organized. ESS is now managing to the established baseline. -A big effort was made in the last 10 months to build up an organization structure with names and clear responsibilities attached to it -The management of the project is strong, well determined, motivated and success oriented. The ESS overall schedule foresees first protons on target in December The cost cap has been fixed to B€ (year 2013). -ESS will start real construction work in June 2014 (ground break) Project Review November 2013

33 CERN Rüdiger Schmidt Nine months at ESSpage 33 Schedule Priority – Facility construction complete at the end of 2022 with 5 MW capability installed; Operations Linked to Construction Progress – Initial operations in 2019 (production of 1 st neutrons) and facility operations in 2023 (instruments available for the user program); Scope Contingency - Explicit scope contingency integrated into the accelerator plans (scope that can be delayed if necessary); Instrument Program – Technically limited schedule, leverage construction investment, plan for additional investment; Conventional facilities costs above the cost report value covered outside the cap by the host countries or new partners; Plan A and other plans…
