Superconducting Shadows Experiment: Concept for Measuring the Anisotropic Field of a Particle Using a Superconducting Layer and SQUID Detection

This work presents a conceptual design of an experiment that uses a thin superconducting layer and a SQUID magnetometer to detect extremely weak anisotropic deviations in current density caused by the presence of a single particle. According to the TMD framework, massive particles generate a subtle non‑magnetic field that may manifest in a superconductor as an orientational shadow—a small but systematic modification of the local current distribution. The paper outlines the choice of superconducting material, layer thickness, operating temperature, current geometry, and the SQUID measurement protocol. Order‑of‑magnitude estimates show that the expected magnetic‑flux deviation ΔΦ ∼ 10⁻⁶ − 10⁻⁹ Φ₀ lies within the sensitivity range of modern SQUID devices.The proposed setup provides a realistic pathway for experimentally testing the existence of the orientational shadow predicted by TMD.
