Description
The European Spallation Source Neutrino Super Beam + ( ESSnuSB+) project aims to make precision measurements of neutrino-nucleus interaction cross sections. To do this it will utilize the impact of a 1.25 MW proton pulse from the ESS (European Spallation Source) Linac on a target with the ultimate aim of creating a muon and electron neutrino beam from a muon decay ring (based on a low-energy version of the neutrinos from stored muons proposal, LEnuSTORM). In order to achieve this, it is necessary to transport pions downstream of the target system from the megawatt-class target station environment through the radiation shielding to a point where they can be injected into the decay ring.
This requires the design of a capture and focus system for the pions, as well as a transfer line with a large acceptance both in terms of the momentum spread and in the transverse directions. The design of this transfer line is constrained by the short decay length of the low-energy pions, and must meet the layout considerations whilst maintaining an appropriate momentum acceptance and a minimum overall length. This presentation discusses considerations for the capture, transport, and injection of low energy pion beams and how these may be implemented at the future ESSnuSB+ experiment.
