The instruments selected for construction at the European Spallation Source are versatile, and most serve several different scientific communities. Developed and built by teams across Europe, they are each designed to be world-leading from day one.
The 15 instrument concepts were selected through an inclusive process, involving applications from the community and peer-review by scientific and technical committees. The final recommendation was made by the ESS Scientific Advisory Committee and approved by ESS Council. Expansion of the suite up to 22 instruments is anticipated, and the facility is designed to accommodate even more in the future. Installation of the first instruments will begin in 2019, followed by hot commissioning in 2021, and the user program for the earliest instruments is set to open in 2023.
