Description
The CERN secondary beamlines of the North and the East Area deliver beams of secondary and tertiary particles, as well as attenuated primary protons and ions. These beams are driven by the SPS and PS accelerators, and used for fixed target experiments and beam tests. Protons with 24 GeV/c at the PS and with 400 GeV/c at the SPS produce typically hadrons, electrons, and muons within a wide range of momenta between 0.1 GeV/c and 360 GeV/c at fluxes from several $100$s up to $10^{9}$ particles per spill that serve several experimental areas throughout the complex. The CERN irradiation facilities will also be discussed, specifically GIF++, IRRAD and CHARM. IRRAD and CHARM are driven by the PS primary proton beam at 24 GeV/c with up to $8\times10^{11}$ protons per spill.
This talk will present the features of the different beam lines and beams serving the various fixed target experiments and test beam areas, including beam properties, available infrastructure for tests and beam instrumentation, e.g. the installed beam telescopes. Measurements of the beam performance are shown following the recent extensive consolidation activities and beamline improvements throughout. Future plans are also presented including beam control software upgrades during LS3 as well as planned upgrades for the beamlines.
