Nuclear-physics experiments probe nuclear structure, nucleosynthesis and fundamental interactions, for which high precision and accurate mass measurements are critical inputs. TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN) facility employs the Measurement Penning Trap (MPET) to measure masses of exotic nuclei to high precision and accuracy up to ~1e-10. To improve the resolving power...
nEXO is a next generation detector to search for neutrinoless double-beta decay in Xe-136. This hypothetical decay violates lepton-number conservation, requiring the neutrino to be its own antiparticle and would imply the existence of physics beyond the Standard Model. As a potential upgrade to further improve nEXO’s sensitivity, the Ba-tagging technique is being developed to eliminate nearly...
The neutron dose responses of the tissue equivalent multi-element Thick Gas Electron Multiplier (THGEM) microdosimetric detectors have been computed by Monte Carlo simulations. The absence of wire electrodes in THGEM has immensely simplified the construction of multi-element detectors. Three muti-element configurations of 7x3, 19x5, 37x7 were used as the representative detector geometries and...
We present optimization and characterization of a Si-plastic scintillator coincidence beta-ray spectrometer. Recent recommendation to lower the dose limit for the lens of the eye by International Commission on Radiological Protection posed new health physics requirement in the country. Beta-ray dosimetry is of great importance for nuclear industries, particularly during the maintenance...
