Description

A new opportunity for a possible flagship experiment in Europe opens by exploiting a unique opportunity that has long been hidden in the Chooz site — Europe’s most famous site for reactor neutrino science. The “SuperChooz” project benefits by existence of 2 caverns, formerly hosting the Chooz-A nuclear reactor, built in the 60’s, that are becoming vacant upon its dismantling completion. They hold a total volume of up to 50 000m^3, thus directly comparable to the size of SuperKamiokande. Its potential use for for science purposes is under active discussion with EDF and dedicated agreement has just been signed, thus starting the official pathfinder exploration era. The SuperChooz caverns combined with the existing ~1km baseline of the most powerful 2x N4 Chooz PWR nuclear reactors make this site a unique asset world-wide. Experimentally, the challenge is the poor overburden (order 100m underground). However, the novel LiquidO technology, born as byproduct of Double Chooz, heralds the potential for unprecedented active background rejection of up to 2 orders of magnitude, thus providing feasibility potential ground for a hypothetical SuperChooz. The rationale of the experiment will be highlighted in the talk for the first time — first official released. The project is aimed to address some of the most fundamental symmetries (studies under completion) behind the Standard Model, including a design that may open for key synergies that may boost the sensitivities of other neutrino flagship experiments such as DUNE (US), JUNO (China) and HyperKamiokande (Japan).
