Hybrid Nanocomposite Scintillators for Transformational Breakthroughs in Radiation Detection and Neutrino Research

Introduction

The goal of UNICORN is to develop unprecedented nanocomposite scintillator (SL) detectors based on engineered nanomaterials for transformative breakthroughs in strategic radiation detection areas spanning homeland security and medicine to industrial, nuclear, and environmental monitoring to cosmology and high energy/particle physics.

Current Challenges

Today, conventional inorganic SL crystals are prohibitively energy-intensive, fragile, heavy, and cannot be produced in large quantities. Organic SLs are, in turn, affordable and scalable, but their low density and light yield reduce energy resolution.

These shortcomings preclude progress in application areas of great importance and impose a technological bottleneck to the fundamental study of rare events.

Importance of Neutrinoless Double Beta Decay

The most at risk of all is the study of neutrinoless Double Beta Decay (0DBD), a so far undetected, rare nuclear process that represents the Holy Grail in particle physics. Its observation would provide long sought-after answers on the origin of the Universe and unlock unexplored scientific territories with unimaginable progress perspectives.

Project Approach

UNICORN will tackle this urgent grand challenge by introducing revolutionary nanotechnology-based concepts combining:

1. High energy resolution
2. Efficiency
3. Stability
4. Unmatched mass scalability

The keystone of our disruptive approach are inorganic nanocrystals (NCs) that will be specifically designed to be both the source of 0DBD and high-performance nano-SLs.

Breakthrough Objectives

The breakthrough will also consist in achieving perfect compatibility with (in)organic hosts to obtain unparalleled ultra-high density optical-grade nanocomposite detectors with maximized light output. These will be coupled to custom-made light sensors that will embody the archetype of advanced radiation detectors of the future.

Collaborative Effort

UNICORN combines world-leading institutions and companies with complementary interdisciplinary competences, ensuring the pivotal synergy to reach the project goals and rapidly translate results into economic value.
