This report aims to assess the reliability, stability, and reproducibility of a new generation of beam wire scanners developed at CERN in the framework of the LHC Injectors Upgrade (LIU). The study includes data from over 60000 scans performed in 2021 and 2022, with a particular focus on reproducibility, investigation of optimal operational settings to ensure a large dynamic range, and evaluation of absolute accuracy through comparison with other instruments present in the injectors.</description> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Di Carlo, Salvatore</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Andreazza, William</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Belohrad, David</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Emery, Jonathan</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Esteban Felipe, Jose</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Goldblatt, Aurélie</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Gudkov, Dmitry</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Guerrero, Ana</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Jackson, Stephen</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Lacarrere, Guillaume</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Martin Nieto, Miguel</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Rinaldi, Arnaud</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Roncarolo, Federico</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Schillinger, Christiane</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Veness, Raymond</dc:creator> <pubDate>Thu, 16 Mar 2023 06:28:53 GMT</pubDate> <guid>https://cds.cern.ch/record/2852574</guid> <media:content xmlns:media="http://search.yahoo.com/mrss/" url="https://cds.cern.ch/record/2852574/files/document.pdf"/> <dc:title xmlns:dc="http://purl.org/dc/elements/1.1/" xml:lang="fr"/> <dc:hasPart xmlns:dc="http://purl.org/dc/elements/1.1/">['']</dc:hasPart> <dc:hasVersion xmlns:dc="http://purl.org/dc/elements/1.1/"/> </item> <item> <title>Commissioning of the LHC Injectors BWS Upgrade</title> <link>https://cds.cern.ch/record/2815955</link> <description>A novel generation of fast Beam Wire Scanners (BWS), developed in the framework of the LHC Injectors Upgrade (LIU), has been recently deployed in the 3 LHC injector synchrotrons, accelerating protons from 160 MeV to 450 GeV, during the 2019-2020 LHC long shutdown. The monitors feature high precision motor controller, high resolution wire position monitoring and wide dynamic range secondary particles detectors. This contribution will document the commissioning of the 17 new systems during the accelerator complex restart in 2021, which is an exciting and challenging phase in the life cycle of an instrument. A summary of the so far achieved levels of reliability, reproducibility, detectors/DAQ bandwidth and overall accuracy, will be used to revisit the options for further improving the systems’ performance in the future.</description> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Emery, Jonathan</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Andreazza, William</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Belohrad, David</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Di Carlo, Salvatore</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Esteban Felipe, Jose C</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Goldblatt, Aurélie</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Gudkov, Dmitry</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Guerrero, Ana</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Jackson, Stephen</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Lacarrere, Guillaume O</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Martin Nieto, Miguel</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Rinaldi, Arnaud T</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Roncarolo, Federico</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Schillinger, Christiane</dc:creator> <dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Veness, Raymond</dc:creator> <pubDate>Sun, 17 Jul 2022 04:27:08 GMT</pubDate> <guid>https://cds.cern.ch/record/2815955</guid> <media:content xmlns:media="http://search.yahoo.com/mrss/" url="https://cds.cern.ch/record/2815955/files/document.pdf"/> <dc:title xmlns:dc="http://purl.org/dc/elements/1.1/" xml:lang="fr"/> <dc:hasPart xmlns:dc="http://purl.org/dc/elements/1.1/">['']</dc:hasPart> <dc:hasVersion xmlns:dc="http://purl.org/dc/elements/1.1/"/> </item> </channel> </rss>
