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
• f materials over a wide range of length- and time-scales
• life science,
• soft condensed matter research,
• chemistry of materials,
• energy research,
• magnetic and electronic phenomena,
• engineering materials and geosciences,
• archaeology and heritage conservation,
• fundamental and particle physics.

Recipe for a Spallation Source

• Accelerate many many many protons to 1 – 2 GeV
• Proton beam power of several MW, 1.5 * 1016 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

ESS specific

• ESS is an emerging research laboratory with (still) very limited

capacity in-house

• Collaborative projects: Work in a collaboration where the scope
• f 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

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
• perations including the completion and commissioning of

the final 22 public instruments.

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)

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, ….)

• The first ESS annual review took place at LUND the 12th-14th November 2013
• 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
• rganized. 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 2019. The cost cap has been fixed to 1.843 B€ (year 2013).

• ESS will start real construction work in June 2014 (ground break)

Project Review November 2013

SLIDE 33

CERN

Rüdiger Schmidt Nine months at ESS page 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 1st 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
• utside the cap by the host countries or new partners;

Plan A and other plans…
