dc.description.abstractWe describe an apparatus used to measure the triple-correlation term (Dn⋅pe×pν)(Dσ̂n⋅pe×pν) in the beta decay of polarized neutrons. The DD coefficient is sensitive to possible violations of time reversal invariance. The detector has an octagonal symmetry that optimizes electron–proton coincidence rates and reduces systematic effects. A beam of longitudinally polarized cold neutrons passes through the detector chamber, where a small fraction undergo beta decay. The final-state protons are accelerated and focused onto arrays of cooled semiconductor diodes, while the coincident electrons are detected using panels of plastic scintillator. Details regarding the design and performance of the proton detectors, beta detectors, and the electronics used in the data collection system are presented. The neutron beam characteristics, the spin-transport magnetic fields, and polarization measurements are also described.en_US

dc.identifier.citedreferenceThe measured flipping ratio was higher in the first run (R = 11.84±0.08)(R=11.84±0.08). This is possibly due to both the cold source upgrade and a shortened Be guide. These changes shift the spectrum to higher wavelength, which lowers the polarizing power of the supermirror.en_US
