位于俄罗斯莫斯科地区的普罗维诺加速器设施在中微子物理领域具有丰富的实验研究项目的优势。特别令人感兴趣的是将中微子束从普罗维诺射向KM3NeT/ORCA探测器的可能性，该探测器目前正在法国土伦40公里外的地中海建造。这一提议被称为P2O。由于其2595公里的基线，该实验将对地球上的物质效应产生无与伦比的灵敏度，允许在仅仅几年的适度光束强度运行后，以高度确定性确定中微子的质量顺序。通过长时间曝光（），可以实现对轻子cp违反狄拉克相的灵敏度。实验的第二阶段，包括加速器综合体的进一步强度升级和ORCA探测器的致密版本（超级ORCA），将允许对CP违反的灵敏度提高，并在使用450千瓦光束运行10年后对CP阶段进行解决，与其他计划的实验竞争。中微子束的初始成分和能谱需要由附近的探测器监测，探测器将在质子束目标下游几百米处建造。同样的中微子束和近探测器装置也将允许进行中微子核截面测量。一个短基线无菌中微子搜索实验也是可能的。
The Protvino accelerator facility located in the Moscow region, Russia, is in a good position to offer a rich experimental research program in the field of neutrino physics. Of particular interest is the possibility to direct a neutrino beam from Protvino towards the KM3NeT/ORCA detector, which is currently under construction in the Mediterranean Sea 40 km offshore Toulon, France. This proposal is known as P2O. Thanks to its baseline of 2595 km, this experiment would yield an unparalleled sensitivity to matter effects in the Earth, allowing for the determination of the neutrino mass ordering with a high level of certainty after only a few years of running at a modest beam intensity of. With a prolonged exposure (), asensitivity to the leptonic CP-violating Dirac phase can be achieved. A second stage of the experiment, comprising a further intensity upgrade of the accelerator complex and a densified version of the ORCA detector (Super-ORCA), would allow for up to asensitivity to CP violation and aresolution on the CP phase after 10 years of running with a 450 kW beam, competitive with other planned experiments. The initial composition and energy spectrum of the neutrino beam would need to be monitored by a near detector, to be constructed several hundred meters downstream from the proton beam target. The same neutrino beam and near detector set-up would also allow for neutrino-nucleus cross section measurements to be performed. A short-baseline sterile neutrino search experiment would also be possible.
