The importance of Machine protection The ESS facility is a large and complex machine that represents an enormous investment from the member countries Operational safety, availability and reliability is of utmost importance Machine protection reliably protects the machine from damage and from unnecessary beam-induced activation Machine protection is designed to optimize availability and support failure localization Cost example for unplanned down-time – 25 k€ / hour – 600 k€ / day – 4.2 M€ / week – 18 M€ / month 6

Thank you for coming! ESS is a very young project We are dependent on comprehensive external assessments of different aspects of our projects We are very grateful for the experience you share We value your advice on how to improve through constructive feedback and recommendations 7

Thank you!
