The Hollow Electron Lens (HEL) was proposed to actively remove the beam halo of the proton beam for the HL-LHC upgrade. Currently, the concept of generating such an electron beam is being tested in a dedicated Electron Beam Test Stand (EBTS) at CERN. It currently produces a hollow electron beam with 7 keV energy and 0.4 A current 25 us pulsed with 2 Hz which will be confined in a strong solenoid field. A gas curtain-based beam profile monitor was developed to characterize the beam non-invasively during operation. It injects a directional gas sheet at 45 degrees to interact with the electron beam. Gas particles are excited and emit fluorescent photons which are collected by an intensified camera system. This allows the reconstruction of the profile of the hollow electron beam. This contribution presents the design of the monitor and discusses the initial results obtained with a hollow electron beam at the EBTS. 899 - ohne Topic (POF4-899) G:(DE-HGF)POF4-899 POF4-899 POF IV 0 Dataset connected to DataCite Accelerator Physics Other mc6-beam-instrumentation-controls-feedback-and-operational-aspects - MC6: Beam Instrumentation, Controls, Feedback and Operational Aspects Other mc6-t03-beam-diagnostics-and-instrumentation - MC6.T03: Beam Diagnostics and Instrumentation Other theory no experiment theory work (theory) EXP:(DE-Ds200)theory-20200803 EXP:(DE-Ds200)no_experiment-20200803 EXP:(DE-Ds200)no_experiment-20200803 0 Sidorowski, Krystian 1 Forck, Peter P:(DE-Ds200)OR0310 2 Udrea, Serban P:(DE-Ds200)OR1313 3 Mazzoni, Stefano 4 Sequeiro, Cristina 5 Welsch, Carsten 6 Sameed, Muhammed 7 Stringer, Oliver 8 Veness, Raymond 9 Lefevre, Thibaut 10 Churchman, Ashley 11 Zhang, Hao P:(DE-HGF)0 12 Corresponding author Ady, Marton 13 Rossi, Adriana 14 Webber-Date, Alexander 15 Schneider, Gerhard 16 Sedlacek, Ondrej 17 10.18429/JACOW-IPAC2023-THPL066 http://repository.gsi.de/record/357735/files/THPL066.pdf OpenAccess http://repository.gsi.de/record/357735/files/THPL066.pdf?subformat=pdfa pdfa OpenAccess oai:repository.gsi.de:357735 openaire open_access VDB driver dnbdelivery GSI Helmholtzzentrum für Schwerionenforschung GmbH I:(DE-Ds200)20121206GSI GSI 2 P:(DE-Ds200)OR0310 GSI Helmholtzzentrum für Schwerionenforschung GmbH I:(DE-Ds200)20121206GSI GSI 3 P:(DE-Ds200)OR1313 DE-HGF Programmungebundene Forschung ohne Programm G:(DE-HGF)POF4-890 G:(DE-HGF)POF4-899 G:(DE-HGF)POF4 G:(DE-HGF)POF4-800 G:(DE-HGF)POF ohne Topic 0 2023 OpenAccess StatID:(DE-HGF)0510 StatID Creative Commons Attribution CC BY 4.0 LIC:(DE-HGF)CCBY4 HGFVOC no I:(DE-Ds200)BEA-20051214OR061 BEA Beam Diagnostics 0 contrib VDB I:(DE-Ds200)BEA-20051214OR061 UNRESTRICTED FullTexts
