IPAC’23 / STUDENT POSTER SESSION GUIDE 17 Student Poster Session SUPM022 Beam Dynamics for Concurrent Operation of the LHeC and the HL-LHC Tiziana von Witzleben (European Organization for Nuclear Research) . Bernhard Holzer (European Organization for Nuclear Research). The Large Hadron Electron Collider (LHeC) is an option for CERN to construct an energy recov- ery linear accelerator tangentially to the HL-LHC (High Luminosity Large Hadron Collider) and would enable deep inelastic scattering collisions between electrons and protons. In this design, one of the proton beams of the HL-LHC goes into collision with the electron beam, while the second proton beam is guided around the collision in this interaction point. The e-p interaction is designed to operate concurrently with p-p collisions in ATLAS, CMS and LHCb. The interaction region is laid out for alternate e-h and h-h data taking using a common detector with ALICE, suitable for this novel way of operation. It therefore requires a highly precise beam optics and orbit for the three beams: the two proton beams of the HL-LHC, as well as the electron beam from the energy recovery linac. The highly asymmetric optics and orbits of the two proton beams, allow- ing concurrent operation of the HL-LHC experiments and e-p collisions, have been modelled in MADx. The impact of an optimized electron minibeta insertion, focusing and bending the electrons, on the proton beam dynamics has been considered. SUPM023 Kaon beam studies employing coventional hadron beam concepts and the RF-separation technique at the CERN M2 beam line for the future AMBER experiment Fabian Metzger (European Organization for Nuclear Research) . Alexander Gerbershagen (Particle Therapy Research Center), Anna Baratto Roldan, Bastien Rae, Di- panwita Banerjee, Florian Stummer, Johannes Bernhard, Maarten Van Dijk, Markus Brugger, Niko- laos Charitonidis, Robert Murphy, Silvia Schuh-Erhard, Vasiliki Stergiou (European Organization for Nuclear Research), Bernhard Ketzer (Universitaet Bonn), Carlo Alberto Mussolini, Luke Dyks (Oxford University), Elisabetta Parozzi (Universita Milano Bicocca), Laurence Nevay (CERN), Laurent Gatignon (Lancaster University), Pascal Simon (GSI Helmholtzzentrum für Schwerionenforschung GmbH). The future AMBER experiment aims to measure the inner structure and the excitation spectra of kaons with a high intensity kaon beam at the CERN secondary beam line M2. One way to identify the small fraction of kaons in the available beam is tagging with the help of differential Cherenkov detectors (CEDARs), whose detection efficiency depends critically on the beam par- allelism. In the framework of the Conventional Beams Working Group of the Physics Beyond Colliders Initiative at CERN, several possible improvements of the conventional beam optics have been studied, trying to achieve a better parallelism, investigating especially the reduction of multiple scattering. Additionally, with the aim of increasing the Kaon purity of the beam, a Radio-Frequency separation technique has been also studied. This method exploits the dif- ferences in velocity due to the particle mass in the beam, kicking out unwanted particles with
