Abstract :
T The MTV (Mott polarimetry for T-Violation) experiment at TRIUMF aims to search a large T-violation in nuclear beta decay outside of the Standard Model. The T-violating transverse polarization of the emitted electrons is measured as left-right scattering asymmetry in backward scattering event by a thin metal foil. The present experiment requires high statistical and systematic precision. In order to achieve a high statistical precision, a high speed-triggering and DAQ system is required. To satisfy the requirements, the FPGA-based Trigger/DAQ system has been developed by the general purpose VME board. The details of the system and performance test results will be reported in this paper.
