dc.description.abstractEnThe article describes the commissioning and technical development of the Weak Interaction Studies with <sup loc="pre">32</sup>Ar Decay (WISArD) experiment, installed at the radioactive ion-beam facility ISOLDE/CERN. The experiment aims to extend the present limits on scalar and tensor currents in the weak interaction and hence search for physics beyond the Standard Model. The evaluation of these limits relies on measuring the proton energy in beta-delayed proton emission, sensitive to both the beta-neutrino angular correlation coefficient <math display="inline" id="d1e1139" altimg="si1.svg"><msub><mrow><mi>a</mi></mrow><mrow><mi>β</mi><mi>ν</mi></mrow></msub></math> and the Fierz interference term <math display="inline" id="d1e1151" altimg="si2.svg"><mi>b</mi></math>. The method tries to improve previous studies by considering the positron-proton coincidences when determining the kinematic shift in the energy of the emitted protons. Using this coincidence technique, the <math display="inline" id="d1e1156" altimg="si1.svg"><msub><mrow><mi>a</mi></mrow><mrow><mi>β</mi><mi>ν</mi></mrow></msub></math> and <math display="inline" id="d1e1169" altimg="si2.svg"><mi>b</mi></math> coefficients will be measured at the per mil level. Simulations were employed to optimize the ion beam transport efficiency and validate proof-of-principle results obtained in November 2018 (Nov2018). Upgrades are ongoing, and we are looking into improvements to the overall performance of the setup.
