Simulations of dynamics and decay in the St. Benedict Paul trap
ORAL
Abstract
Precise measurements of nuclear beta decays provide a unique insight into the Standard Model due to their connection to electroweak interactions. These decays can provide constraints on the unitarity or non-unitarity of the Cabbibo-Kobayashi-Maskawa (CKM) quark mixing matrix, as well as constrain the existence of exotic scalar and tensor currents. At the Nuclear Science Laboratory (NSL) at the University of Notre Dame, the Superallowed Transition Beta-Neutrino Decay Ion Coincidence Trap (St. Benedict) is being constructed to determine the beta-neutrino angular correlation parameter of various superallowed mixed mirror beta decays. Specifically, a linear Paul trap will be used to hold radioactive species until subsequent decay and detection of beta-decay products. Robust simulations of trapped ion dynamics and decay kinematics in the St. Benedict measurement Paul trap will be presented.
