Nettet17. apr. 2024 · called MTV(Mott Polarimetry for T-Violation Experiment)-S1183 has started at TRIUMF, aiming to achieve the highest precision test of time reversal symmetry in polarized nuclear beta decay. In this experiment, existence of T-violating transverse polarization of electrons emitted from polarized nuclei is examined, using Nettetmeasuring electron polarization arise from backgrounds, systematic effects, various “dirt” effects, and possibly statistics. The underlying science that initially drove the need for, and currently drives the required precision of electron polarimetry is parity violation. The reasons for this are fairly straightforward.
