摘要:

本文描述了一种用自旋极化超冷中子精确测量中子$β$不对称性的电子谱仪。该谱仪由一个1.0特斯拉的螺线管场与两个相同的多丝正比室和塑料闪烁体电子探测器包位于0.6特斯拉的场扩展区域内。选择结果与校准源的光谱仪的性能研究报告。

英文摘要:

We describe an electron spectrometer designed for a precision measurement of the neutron $β$-asymmetry with spin-polarized ultracold neutrons. The spectrometer consists of a 1.0-Tesla solenoidal field with two identical multiwire proportional chamber and plastic scintillator electron detector packages situated within 0.6-Tesla field-expansion regions. Select results from performance studies of the spectrometer with calibration sources are reported.
