标题： The WITCH Experiment: towards weak interactions studies. Status and prospects

摘要： WITCH实验的主要目标是测试标准模型，以可能混合标量或张量类型的相互作用在β衰变中。 此信息将从反冲能量谱的形状推断出来。 实验装置已经完成，并正在ISOLDE（CERN）进行密集的调试。 它结合了一个潘宁阱来存储离子和一个减速光谱仪来探测反冲离子的能量。 介绍了WITCH装置的概述以及到目前为止进行的调试测试的结果。 最后，回顾了物理计划的前景。 显示英文摘要

摘要： Primary goal of the WITCH experiment is to test the Standard Model for a possible ad-mixture of a scalar or tensor type interaction in beta-decay. 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.
