The New CERN Low-energy Facilities for Neutrino Detector Tests

The beamlines at CERN’s North and East Areas offer secondary beams in a wide range of momenta between 0.5 GeV/$c$ and 400 GeV/$c$ for fixed-target experiments as well as for test beam campaigns with a flexible configuration and variable beam composition and intensities. Recently, two new facilities for neutrino detectors tests have been established in an extension of the CERN North Area in context of the CERN Neutrino Platform project. These new tertiary beams extend the current capabilities of the H2 and H4 beamlines towards lower momenta in the range of 0.3 GeV/$c$ to 12 GeV/$c$, respectively 7 GeV/$c$, and currently serve the two ProtoDUNE prototype detectors. In addition, a complete overhaul of the CERN East Area is underway, which will provide secondary beams with momenta of up to 15 GeV/$c$ (T9 beam) and 12 GeV/$c$ (T10 beam). New beam optics and an optimised design will allow for electron, hadron and muon beams with high purity. We discuss the layout and performance of both North and East Area beamlines as well as the available infrastructure for the neutrino detector community.
