WP 4 Progress Status Piotr Cupial AGH University of Science and Technology Krakow, Poland Funded by the H 2020 Framework Programme of the European Union ESSnu. SB annual meeting, 7. 11. 2018 1

Target station concept The switching yard is not part of WP 4, it is being studied within WP 3 ESSnu. SB annual meeting, 7. 11. 2018 2

Objectives: • Adapt the EUROnu designed target station to the ESSnu. SB requirements • the target • hadron collector (Horn) • Power Supply Units • Investigate the possibility of using a solenoid based hadron collector • Optimise the facility structure • Simulate the neutrino beam Tasks: Task 4. 1 Coordination of the Target Station study (AGH) Task 4. 2 Adapt the EUROnu design target station to the ESSnu. SB requirements (AGH, CNRS, Uni. Ge) Task 4. 3 Target integration (AGH, CNRS, CERN) Task 4. 4 Optimization of the horn-type hadron collector (CNRS, AGH, CERN) Task 4. 5 Horn current pulse generator (CNRS) Task 4. 6 Alternative hadron collector (UU, CERN) ESSnu.
