对中微子双β衰变的研究可以揭示我们知识中缺失的一个关键部分，即中微子质量的本质。它的观察确实是证明中微子是马约拉纳粒子的最灵敏的实验方法。观察这样一个潜在的罕见过程需要一个具有极好的能量分辨率、极低的放射性和大量发射器同位素的探测器。现在人们追求许多技术，但没有一种技术能同时满足所有的要求。R2D2的目标是证明球形高压TPC可以满足所有要求，并为0νββ衰变搜索提供理想的探测器。在演讲中，我们讨论了R2D2的目标和路线图，以及正在进行的研发和未来的发展。
The search for neutrinoless double beta decay could cast light on one critical piece missing in our knowledge i.e. the nature of the neutrino mass. Its observation is indeed the most sensitive experimental way to prove that neutrino is a Majorana particle. The observation of such a potentially rare process demands a detector with an excellent energy resolution, an extremely low radioactivity and a large mass of emitter isotope. Nowadays many techniques are pursued but none of them meets all the requirements at the same time. The goal of R2D2 is to prove that a spherical high pressure TPC could meet all the requirements and provide an ideal detector for the 0νββ decay search. In the presented talk the R2D2 goal and roadmap are discussed as well as the ongoing R&D and the future developments.
