Objectives:

This Work Package will design the ESS𝜈SB+ target station and involve five European institutions (UNISTRA, CNRS, ESS-Bilbao, UHH and CERN).

The ESS𝜈SB+ target station will be designed to work under a 1.25 MW proton beam power compared to the ESSvSB one which is designed to work at 5 MW. The new proposed studies will adopt the ESSνSB pack-bed target embedded inside one unique Van der-Meer magnetic horn to focus the produced mesons.

The end of the target station facility will be equipped with an extraction and deflection magnetic system that depends on conventional dipoles to bend the secondary beam in horizontal and/or vertical planes. This system will select the secondary particles regarding the physics goals towards the low energy monitored beam facility decay tunnel (LEMNB) or the low energy muon storage ring (LEnuSTORM).

 

A comprehensive study will be conducted on the modifications to the design of one or all of these components, with respect to the physics goals of the ESSνSB+ project. In addition, the shielding of the horn-target gallery and some sensitive parts like the magnetic element will be studied.

This work requires several feedbacks from the other Work Packages to converge on the final design.
