New Directions for ALP Searches Combining Nuclear Reactors and Haloscopes

Abstract

In this work we propose reactoscope, a novel experimental setup for axion-like particle (ALP) searches. Nuclear reactors produce a copious number of photons, a fraction of which could convert into ALPs via Primakoff process in the reactor core. The generated flux of ALPs leaves the nuclear power plant and its passage through a region with a strong magnetic field results in the efficient conversion to photons which can be detected. Such magnetic field is the key component of axion haloscope experiments. Adjacent nuclear reactor and axion haloscope experiment exist in Grenoble, France. There, the Institut Laue-Langevin (ILL) research reactor is situated only $\sim 700$ m from GrAHal, the axion haloscope platform designed to offer several volume and magnetic field (up to 43 T) configurations. We derive sensitivity projections for photophilic ALP searches with ILL and GrAHal, and also scrutinize analogous realizations, such as the one comprising of CAST experiment at CERN and Bugey nuclear power plant. The results that we obtain complement and extend the reach of existing laboratory experiments, e.g. light-shining-through-walls. While the derived sensitivities are not competitive when compared to the astrophysical limits, our analysis is free from the assumptions associated to those.
