Description
The TRUST-ME project is a new application of MUon Survey Tomography based on Micromegas detector for Unreachable Sites Technology (MUST²) to address a societal challenge of increasing importance: sustainable water management. To this end, a network of application-oriented muon trackers is being developed to both survey groundwater in aquifers and enhance the safety and operational efficiency of large structures, such as dams.
This innovative muon tracker, conceived by the Laboratoire Souterrain à Bas Bruit (LSBB), relies on a Micromegas readout plane with a thin time projection chamber [1]. The resulting compact, high field-of-view detector is able to operate in harsh environments with challenging access and deployment conditions. A network comprising a new generation of the detector is being developed within specially developed underground facilities at the LSBB.
Here, we present the context and objectives of the project. We introduce the functioning principles of the detector, and we detail the software and hardware upgrades of the new version. We discuss the technical challenges found while building and configuring the detector network. We present and discuss preliminary data acquired within LSBB (inside a large karstic reservoir) including the reconstruction of muon trajectories inside the detector and ongoing work towards temporal 3D imaging.
