Description
The NA61/SHINE Collaboration has successfully measured hadron production in hadron–nucleus interactions over a momentum range of 30–120 GeV/c for neutrino experiments. These measurements have provided essential inputs for neutrino experiments such as T2K and those at Fermilab. Recently, there has been an increasing demand for NA61/SHINE to perform measurements with hadron beams at momenta below the operational range of the current SPS H2 beamline. In response, a low-energy (low-E) beamline has been designed to deliver secondary hadron beams with momenta as low as approximately 2 GeV/c, while preserving the capability for high-energy operations up to 400 GeV/c. We have actively engaged with the neutrino community and other relevant physics communities to demonstrate that the availability of a low-E beam is crucial for advancing a wide range of physics programs, including next-generation neutrino experiments such as Hyper-Kamiokande and DUNE. This poster will present an overview of the low-E beamline project, its current status and future prospects, and the expected physics impact of future hadron production measurements using low-E beams.
