This paper presents a rotating-coil measurement system that aims at providing a complete data set for the characterization of quadrupole magnets with small bore diameters (26 mm). The PCB magnetometer design represents a challenging goal for this type of transducer. It is characterized by an aspect ratio 30% higher than the state of the art, imposed by the reduced dimension of the external radius of the rotating shaft and the necessity of covering the entire magnet effective length (500 mm or higher). The system design required a novel design for the mechanical asset, also considering the innovation represented by the commercial carbon fiber tube, housing the PCB magnetometer. Moreover, the measurement system is based primarily on standard and commercially available components, with simplified control and post-processing software applications. The system and its components are cross-calibrated using a stretched-wire system and another rotating-coil system. The measurement precision is established in a measurement campaign performed on a quadrupole magnet characterized by an inner bore diameter of 45 mm.<\/jats:p>","DOI":"10.3390\/s22218359","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T06:49:02Z","timestamp":1667371742000},"page":"8359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Rotating-Coil Measurement System for Small-Bore-Diameter Magnet Characterization"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5728-1259","authenticated-orcid":false,"given":"Anna","family":"Lauria","sequence":"first","affiliation":[{"name":"Department of Electronics and Telecommunications, Polytechnic of Turin, 10129 Turin, Italy"},{"name":"Technology Department, European Organization for Nuclear Research (CERN), 1211 Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5192-5922","authenticated-orcid":false,"given":"Pasquale","family":"Arpaia","sequence":"additional","affiliation":[{"name":"Technology Department, European Organization for Nuclear Research (CERN), 1211 Geneva, Switzerland"},{"name":"Department of Electrical Engineering and Information Technology, University of Naples Federico II, 80131 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5752-1865","authenticated-orcid":false,"given":"Marco","family":"Buzio","sequence":"additional","affiliation":[{"name":"Technology Department, European Organization for Nuclear Research (CERN), 1211 Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4773-5798","authenticated-orcid":false,"given":"Antonio","family":"Gilardi","sequence":"additional","affiliation":[{"name":"SLAC National Accelerator Laboratory, Menlo Park, CA 94025, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9723-6188","authenticated-orcid":false,"given":"Marco","family":"Parvis","sequence":"additional","affiliation":[{"name":"Department of Electronics and Telecommunications, Polytechnic of Turin, 10129 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0707-4569","authenticated-orcid":false,"given":"Mariano","family":"Pentella","sequence":"additional","affiliation":[{"name":"Technology Department, European Organization for Nuclear Research (CERN), 1211 Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucia","family":"Sabbatini","sequence":"additional","affiliation":[{"name":"Frascati National Laboratory, National Institute for Nuclear Physics (INFN), 00044 Frascati, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enzo","family":"Simoni","sequence":"additional","affiliation":[{"name":"Facult\u00e9 de Mesures Physiques, Institut Universitaire de Technologie, Universit\u00e9 Savoie Mont-Blanc, 74000 Annecy, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Vannozzi","sequence":"additional","affiliation":[{"name":"Frascati National Laboratory, National Institute for Nuclear Physics (INFN), 00044 Frascati, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bernius, C.
