| Description
| - The standard model of the electroweak interaction describes beta-decay in the well-known V–A form. 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 beta-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.

- Standardní model elektroslabých interakcí popisuje beta-rozpad dobře známou V-A formou. Nicméně nejobecnější Hamiltonián beta-rozpadu obsahuje rovněž další možné typy interakce, např. skalární (S) a tenzorovou (T), které nejsou dosud plně experimentálně vyloučeny. Experiment WITCH si klade za cíl studovat možnou příměs těchto exotických typů interakce v beta-rozpadu pomocí přesného měření energetického spektra odražených jader. Experimentální zařízení obsahuje dvojitý systém Penning pastí a retardačního spektrometru. Zařízení je instalováno na ISOLDE v CERNu a v současnosti je plně funkční. V článku je prezentován současný stav zařízení, data získaná během měření v r.2006 včetně prvního spektra odražených jader, které jsme naměřili. Podrobněji je popsána i procedura nabírání dat a systém sběru dat. Krátce jsou shrnuty další plánované technické úpravy zařízení. (cs)
