提出了一种用于双β衰变实验的磁跟踪探测器DCBA（Drift Chamber Beta-ray Analyzer）。DCBA项目分为两个阶段：DCBA-I和-II。DCBA-I将能够测量150 Nd的双中微子双β衰变的半衰期，尽管天然Nd被用作衰变源材料。DCBA-II将使研究低至0.5-0.1 eV的马约拉纳中微子的有效质量成为可能，因为它预计有能力使用富集的150 Nd测量高达4 × 1024年的半衰期极限。DCBA项目的基本策略和DCBA-I的一些细节进行了描述。
A magnetic tracking detector called DCBA (Drift Chamber Beta-ray Analyzer) is proposed for double beta decay experiments. The DCBA project is divided into two stages: DCBA-I and -II. DCBA-I will be able to measure the half life of the two-neutrino double beta decay of150Nd, though natural Nd is used as the decay source material. DCBA-II will make it possible to investigate the effective mass of the Majorana neutrino down to 0.5-0.1 eV, since it is expected to have the ability to measure the half-life limit up to 4 × 1024yr using enriched150Nd. A fundamental strategy of the DCBA project and some details of DCBA-I are described.
