The European Spallation Source
• An accelerator-based neutron source to be built in
Lund, southern Sweden
– Material and life sciences research
• Targeted to be the world’s most powerful neutron
source

repetition rate, 2.86 ms pulse@65 mA beam current
– Superconducting linac, rotating tungsten target
– 22 neutron beam lines in construction budget
6
The European Spallation Source
• First protons planned by
2019
• Project completion by 2025
– Full beam power, 22 neutron
beam lines
• Accelerator in
Lund,Sweden and data
processing center in
Copenhagen, Denmark

Target and the neutron beam lines
Rotating wheel target – beam has to
hit in the middle of the sector.

ESS construction has started!
ESS is funded
and
Construction is
underway!
This aerial photo has been
taken about some weeks ago.

ESS Control System
• ESS Integrated Control System Division (ICS) is in charge
of building the control system(s) for the accelerator, the
neutron target, and providing controls for the beamline
components (in cooperation with the colleagues from
science directorate)
• Project scope includes also
– Conventional facilities control integration
– Safety & Protection Systems (Machine, Personnel)
– Global Timing System for site-wide synchronization
• Some parts of the controls will be provided by ESS
partner laboratories as in-kind contributions
– e.g., proton source and LEBT controls by Saclay (France)

How much?

Some technology decisions
• Using EPICS for controls in the whole facility
– From accelerator to neutron beamlines
– Plan to benefit from EPICS version 4 facilities
• pvAccess as the binding communicating layer
• Services (e.g. physics model as a service) for the accelerator
• Participating in the DISCS (Distributed Services for Controls)
collaboration
– Databases and applications for facility and device configuration data
– Middle-layer services (see http://openepics.sourceforge.net/)
• CS-Studio as the generic user interface tool
– Control room, subsystem developers, etc.
• Committed to work together with the EPICS and Accelerator
community
– Combining our resources we can make more and better things
17
Technology decisions cont.
• Using MRF event system for global timing
– Synchronization in the whole facility
– Timing supports beam synchronous applications (in
discussion with PSI about co-development)
– Looking at future developments together with some new
projects (ELI-Beams, SwissFEL, others)
• Machine protection is of prime importance
– Ability to switch off beam mid-pulse (10 us time range)
• FPGA-based fast interlock
• Slow devices connected to PLC-based system
– Has to be synchronized with beam operation
• Ramping up with beam intensity, pulse length and repetition rate
18
Controls hardware decisions
• Defining hardware standards – for the whole spectrum
– Standardize on one PLC brand – as far as we can
• To reduce complexity
– Digital platform form factor
• One form factor should cover the segment of fast signal processing
– Mainly beam diagnostics and LLRF
• Going towards MTCA.4 – carefully, though
– Still a new standard with compatibility, etc., issues
• Setting up collaborations for a full framework
– FMC standards, development framework for the whole cycle
(HW&FW&SW)
– Plan to use EtherCAT for middle range between PLCs and MTCA
• pulse-synchronized operations, distributed, kHz range acquisition
19
Controls platforms
• Evaluating motion controller platforms
– Current designs based on DeltaTau GeoBrick
– Working together with colleagues from science directorate
• Controls network design starting
• a network and servers expert hired recently
• Server hall (Lund site) design ongoing
• Starting to look at virtualization solutions
– “soft” IOC deployment, development servers
• Collaborative tools in heavy use
– Atlassian toolkit: JIRA (bugtracker), Confluence (Wiki, web
tool) and BitBucket (repository/Git management)
20
Common services
• Configuration databases and related tools
– (Controls) configuration, cabling, naming service, access control
(RBAC) etc.
• IOC development workflow and tools
– Still searching for optimal development and deployment flow
• How to deploy 600+ IOCs in a short time?
• How to manage these after deployment?
• How to support our off-site partners>
– “IOC Factory” – you will hear about that in the future
• Use tools from the community whenever possible
– CS-Studio, Archiver, Save&Restore, alarm handler
– Contribute to development when appropriate
• Use resources to develop things that do not exist
– Our local infrastructure, for example…
21
Summary
• ESS construction has started
– New accelerator, new institute, new…everything
– Roll up the sleeves and start building systems
• Control system effort is ramping up
– Moving from prototyping to design decisions
– Hiring people (watch our web pages!)
– Working in collaborations and with in-kind contributors in
member states (still looking for partners)
• Lots of things to build
– Many challenges, many opportunities
