Low-background applications of MICROMEGAS detector technology

Abstract

The MICROMEGAS detector concept, generally optimized for use in accelerator experiments, displays a peculiar combination of features that can be advantageous in several astroparticle and neutrino physics applications. Their sub-keV ionization energy threshold, excellent energy and space resolution, and a simplicity of design that allows the use of radioclean materials in their construction are some of these characteristics. We envision tackling experimental challenges such as the measurement of neutral-current neutrino-nucleus coherent scattering or Weakly Interacting Massive Particle (WIMP) detectors with directional sensitivity. The large physics potential of a compact (total volume O(1)m${}^3$), multi-purpose array of low-background MICROMEGAS is made evident.
