This information will be inferred from the shape of the recoil energy spectrum. The experimental set-up 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.

  • Experimental Physics Division
    Experimental Physics Division The LEP Programme ALEPH In 2003 the ALEPH Collaboration (Aachen, Annecy, Barcelona, Bari, Beijing, CERN, Clermont-Ferrand, Copenhagen, Demokritos, Ecole Polytechnique, Firenze, Frascati, Glasgow, Haverford College, Heidelberg, Imperial College, Innsbruck, Lancaster, Louvain-la-Neuve, Mainz, Marseille, Milano, MPI München, Orsay, Pisa, RAL, Royal Holloway, Saclay, Santa Cruz, Sheffield, Siegen, Trieste, Washington, Wisconsin, Zurich) completed and published several final physics analyses. The data collected during the life of the experiment and the software developed over many years have been archived to allow long-term analysis of ALEPH data. The final results on the search for the lightest supersymmetric particle (LSP), one of the main candidates for explaining the existence of the dark matter in the universe, have been complemented by a thorough search for stable hadronizing squarks and gluinos. The analysis of event-shape variables and inclusive particle spectra at the highest LEP energies was completed and the energy evolution of the strong coupling constant was studied in detail. The cross-section of the process e+e– → W+W– was measured with high precision. Many interesting results in two-photon physics were published. Overall, 15 papers were published or submitted for publication by ALEPH during 2003. Searches Charginos and Neutralinos were searched for in the data collected at centre-of-mass energies up to 209 GeV. In the many topologies considered, the number of candidates observed was consistent with the background expected from Standard Model processes. An absolute lower limit of 43.1 GeV/c2 was derived on the mass of the LSP, assumed to be the lightest neutralino, in the framework of MSSM and R-parity conservation.

The KATRIN experiment is going to search for the mass of the electron antineutrino down to 0:2 eV=c2. In order to reach this sensitivity the background rate has to be understood and minimised to 0:01 counts per second. One of the background sources is the unavoidable Penning-like trap for electrons due to the combination of the electric and magnetic fields between the pre- and the main spectrometer at KATRIN. In this article we will show that by sweeping a conducting wire periodically through such a particle trap stored particles can be removed, an ongoing discharge in the trap can be stopped, and the count rate measured with a detector looking at the trap is reduced.

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 124In 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.

Nevertheless, the most general Hamiltonian of a beta-decay includes also other possible interaction types, e.g. scalar (S) and tensor (T) contributions, which are not fully ruled out yet experimentally. The WITCH experiment aims to study a possible admixture of these exotic interaction types in nuclear β-decay by a precise measurement of the shape of the recoil ion energy spectrum. The experimental set-up couples a double Penning trap system and a retardation spectrometer. The set-up is installed in ISOLDE/CERN and was recently shown to be fully operational. The current status of the experiment is presented together with the data acquired during the 2006 campaign, showing the first recoil ion energy spectrum obtained. The data taking procedure and corresponding data acquisition system are described in more detail. Several further technical improvements are briefly reviewed.

  • Standard Model Tests with Trapped Radioactive Atoms 2
    TOPICAL REVIEW Standard Model tests with trapped radioactive atoms ‡ J.A. Behr1 and G. Gwinner2 1 TRIUMF, 4004 Wesbrook Mall, Vancouver, British Columbia V6T 2A3 Canada 2 Department of Physics and Astronomy, University of Manitoba, Winnipeg, Manitoba R3T 2N2 Canada E-mail: [email protected], [email protected] Abstract. We review the use of laser cooling and trapping for Standard Model tests, focusing on trapping of radioactive isotopes. Experiments with neutral atoms trapped using modern laser cooling techniques are testing several basic predictions of electroweak unification. For nuclear β decay, demonstrated trap techniques include neutrino momentum measurements from beta-recoil coincidences, along with methods to produce highly polarized samples. These techniques have set the best general constraints on non-Standard Model scalar interactions in the first generation of particles. They also have the promise to test whether parity symmetry is maximally violated, to search for tensor interactions, and to search for new sources of time reversal violation. There are also possibilites for exotic particle searches. Measurements of the strength of the weak neutral current can be assisted by precision atomic experiments using traps loaded with small numbers of radioactive atoms, and sensitivity to possible time-reversal violating electric dipole moments can be improved.
