Time Reversal in Polarized Neutron Decay - The emiT Experiment
Abstract
The emiT experiment searches for time reversal violation in polarized neutron decay in the form of the angular correlation hatσ_n\cdothatp_e×hatpp using a novel octagonal detector to optimize electron-proton coincidence rates. emiT had its first run from Dec. 1996 through Sept. 1997. Analysis of this data, including an investigation of systematic effects will be reported. Preparations for a second data collection run are underway. Detector upgrades include fiber optic coupling of the proton detectors to analog electronics, improved DAQ hardware, and the replacement of the PIN diode proton dectectors with PIPS or surface barrier detectors. This second run should take place at NIST in the spring of 2000 with the goal of sensitivity to the D coefficient of 2×10-4.
