“…All major components of the set-up including beamline transport, double Penning trap system and the retardation spectrometer are checked for their functionality and show good or acceptable efficiency ( Table 1). The overall efficiency of the set-up was improved by up to a factor of 30 in comparison with 2004 (see [13]). This allowed to detect first recoil ions in the WITCH set-up.…”

Primary goal of the WITCH experiment is to test the Standard Model for a possible admixture of a scalar or tensor type interaction in β-decay. This information will be inferred from the shape of the recoil energy spectrum. The experimental setup was completed and is under intensive commissioning at ISOLDE (CERN). It combines a Penning trap to store the ions and a retardation spectrometer to probe the recoil ion energy. A brief overview of the WITCH set-up and the results of commissioning tests performed until now are presented. Finally, perspectives of the physics program are reviewed.

“…In the past few years the WITCH set-up has been extensively tested and optimized [35,36]. In order to test the operation of WITCH and to measure a first recoil energy spectrum an isotope which decays via beta-minus decay and which has a low ionization potential, 124 In, was chosen.…”

Abstract. The WITCH experiment (Weak Interaction Trap for CHarged particles) will search for exotic interactions by investigating the β-ν angular correlation via the measurement of the recoil energy spectrum after β decay. As a first step the recoil ions from the β − decay of 124 In stored in a Penning trap have been detected. The evidence for the detection of recoil ions is shown and the properties of the ion cloud that forms the radioactive source for the experiment in the Penning trap are presented.PACS. 23.40.Bw Weak-interaction and lepton (including neutrino) aspects -29.30.Aj Charged-particle spectrometers: electric and magnetic -37.10.Ty ion trapping
