短基线近探测器时间投影室在其电荷读出平面的设计上是独一无二的。这些阳极平面组件（APA）的制造和组装符合严格的准确度和精度要求：每个阿帕的3，964根导线的导线间距为3 mm +/- 0.5 mm，导线张力为7 N +/- 1 N，每个阿帕的4 m x 2.5 m范围内的平整度为0.5 mm。本文介绍了这些关键探测器部件的设计、制造和装配，重点介绍了每个阶段的质量保证。
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.
