Preliminary results indicate the benefits of combining easy and complex measurement systems, where the familiar multimeter-alkaline batteries combination facilitates quick comprehension of basic concepts, while the unconventional plastic rule-pencils combination poses unique challenges. Analytic Hierarchy Process (AHP) is applied for a structured quantitative comparison of the instrument/pieces combinations. The findings emphasize the importance of considering system complexity in interpreting GR&R results, highlighting the need for students to apply basic concepts to unconventional situations.

The main challenge in performing these measurements is related to the sensitivity of the transducer, as the field values achievable in the magnet bore are in the 1 mT range. The single stretched-wire method is a proven technique for measuring DC-powered normal-conducting and superconducting accelerator magnets. It is vastly used to locate the magnetic axis in quadrupole magnets and higher-order magnets for their alignment and positioning in the accelerator. However, it fails to provide accurate measurements when used to measure superconducting magnets at room temperature because the typical magnet current levels are three orders of magnitude lower than the nominal level used in operation, leading to field values scaling by the same order of magnitude. The problem of the alignment of superconducting quadrupole magnets at room temperature has already been addressed in the literature by adopting alternating current (AC) magnet powering to enhance measurement sensitivity. This paper presents a comprehensive overview of the single stretched-wire method with AC magnet powering, showcasing the different performance compared with the DC powering technique. To further validate the method, a case study of a superconducting quadrupole magnet is presented, and the results are compared against those from a rotating coil scanner.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"38 ","pages":"Article 101429"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability to simulate various environmental conditions, including interference and noise, allows learners to experiment with different radar parameters such as antenna alignment and operating frequency. This interactive learning environment accelerates the comprehension of complex radar concepts, from the Doppler effect to signal processing techniques, facilitating a deeper understanding of FMCW radar operations. As a teaching example, we propose and compare the simulation results of two radars with different radar parameters and antenna configurations. Additionally, we discuss how the standalone simulation results can be integrated and utilized as inputs for other tools using co-simulation approach.
