Description
The seek for neutrinoless double beta decay as an experimental proof of the nature of the neutrino mass is currently a driving effort in neutrino physics. The deep connection with the possible Majorana nature and the mass origin of the neutrino make this observation one of the hottest topic in particule physics. The observation of such a potentially rare process requires a detector with an excellent energy resolution, extremely low background 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 filled with xenon gas could meet all the requirements and provide an ideal detector for the 0νββ decay search. The prototype has demonstrated an excellent resolution with argon at low pressure and test at higher pressure are ongoing. The xenon recuperation and recirculation systems are under commissioning and results in xenon will be obtained soon. In the proposed poster the R2D2 results obtained with the second prototype will be discussed as well as the project roadmap and future developments.
