Popis: Agradecimentos: This material is based upon work supported by the National Science Foundation under Grant No. PHY-1428753. The US team would also like to thank Lee Greenler for his work designing and prototyping the manual winding apparatus, Tom Hurteau and Frank Lopez for their invaluable support, Aditi Shetty, Annie Polish, Anna Gumberg, Brendon Bullard and London Cooper-Troendle for their contributions to the wire-winding effort at Yale, and all the staff at Wright Lab for their tremendous hospitality to our wire-winding team. This work was supported in the UK by the Science and Technology Facilities Council (STFC), part of United Kingdom Research and Innovation, and the Royal Society of the United Kingdom. The UK team would like to thank Jonathan Mercer for his work in designing and fabricating the wire support combs; Simon Dixon for the APA frames; and Mike Perry for his support. We also thank the staff of the Daresbury Laboratory (UK), in particular Alan Grant, for the provision of Laboratory space and significant technical support Abstract: The Short-Baseline Near Detector time projection chamber is unique in the design of its charge readout planes. These anode plane assemblies (APAs) have been fabricated and assembled to meet strict accuracy and precision requirements: wire spacing of 3 mm +/- 0.5 mm and wire tension of 7 N +/- 1 N across 3,964 wires per APA, and flatness within 0.5 mm over the 4 m x 2.5 m extent of each APA. This paper describes the design, manufacture and assembly of these key detector components, with a focus on the quality assurance at each stage Aberto
