Experimental setup for Weak Interaction Studies with Radioactive ion-beams WISArD
/ Atanasov, D (CERN) ; Cresto, F (LPC, Caen) ; Nies, L (CERN) ; Pomorski, M (LP2I, Bordeaux) ; Versteegen, M (LP2I, Bordeaux) ; Alfaurt, P (LP2I, Bordeaux) ; Araujo-Escalona, V (Leuven U.) ; Ascher, P (LP2I, Bordeaux) ; Blank, B (LP2I, Bordeaux) ; Daudin, L (LP2I, Bordeaux) et al.
The article describes the commissioning and technical development of the Weak Interaction Studies with 32Ar 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. [...]

Magnetic Moments of Short-Lived Nuclei with Part-per-Million Accuracy: Toward Novel Applications of $\beta$-Detected NMR in Physics, Chemistry, and Biology
/ Harding, R.D. (CERN ; York U., England ; U. Nottingham) ; Pallada, S. (CERN) ; Croese, J. (CERN ; Geneva U.) ; Antušek, A. (Slovak Tech. U.) ; Baranowski, M. (Mickiewicz U., Poznan) ; Bissell, M.L.

We determine for the first time the magnetic dipole moment of a short-lived nucleus with part-per-million (ppm) accuracy. To achieve this two orders of magnitude improvement over previous studies, we implement a number of innovations into our $\beta$-detected Nuclear Magnetic Resonance ($\beta$-NMR) setup at ISOLDE/CERN.

Simultaneous measurements of the $\beta$ -neutrino angular correlation in $^{32}$Ar pure Fermi and pure Gamow-Teller transitions using $\beta$ -proton coincidences

We report first time measurements of the beta-neutrino angular correlation based on the kinetic energy shift of protons emitted in parallel or anti-parallel directions with respect to the positron in the beta decay of $^{32}$Ar. This proof of principle experiment provided simultaneous measurements for the superallowed 0$^+$~$\rightarrow$~0$^+$ transition followed by a 3356~keV proton emission and for a Gamow-Teller transition followed by a 2123~keV proton emission.

A beamline dedicated to the production of laser-polarized radioactive beams has been constructed at ISOLDE, CERN. We present here different simulations leading to the design and construction of the setup, as well as technical details of the full setup and examples of the achieved polarizations for several radioisotopes [...]

Following a growing interest in spin-polarized beams of radioactive ions, a new laser spin-polarization setup has been installed at the ISOLDE facility at CERN. The setup is located at the VITO beamline which aims to bring together several experimental techniques using polarized ions allowing for studies in nuclear physics, fundamental interactions, material and life sciences.
