REVEAL

REVEAL is a collaboration between e2v, RSK, Gooch Housego (G&H) and the University of Birmingham (UoB) to develop and trial the first commercial prototype QT gravity gradiometer sensor. It builds on the successful InnovateUK SIGMA/SIGMA+ & FreezeRay/FreezeRay2 projects. SIGMA/SIGMA+ have already developed tools (forward models, improved understanding of noise sources) to provide a more informed assessment of the detectability of targets of interest to their clients. The FreezeRay projects have already enabled e2v and Gooch & Housego to develop sub-systems for quantum gravimeters based on UoB knowledge and expertise. The specific developments within the FreezeRay projects have enabled the consortium to develop the core systems required for a quantum sensor. REVEAL will, for the first time, build an industrial gravity gradiometer prototype based on the knowledge gained at the UoB and through IUK projects and place it in the hands of an expert geophysical surveying company. This is the next logical step for the route to market of these instruments. As well as opening access to the QT research market, this primarily provides a direction towards the creation of a commercial QT supply chain in the UK - aiming to enhance the uptake by industry, and alongside demonstrations, create market growth and wealth creation.To achieve the aim of a first commercial QT gravity gradiometer prototype, REVEAL will focus on the following key steps: 1) Development of ruggedized laser and control systems, 2) Creation of a sensor platform including a vacuum system, 3) System integration into a mobile, transportable unit suitable for civil engineering applications, 4) Knowledge transfer from UoB to e2v and G&H for the sensor requirements and 5) Field trials and survey optimisation to feed back into the sensor development requirements and benchmark against existing geophysical systems.REVEAL will accelerate the commercialisation of QT gravity instruments in two ways: 1) ensuring that the sensor development and system engineering efforts produces instruments that are fit for purpose by providing sensor configuration and performance parameters, 2) increasing the marketplace for the sensors by engagement with the client base, excellent dissemination activities, and practical field demonstrations of prototype equipment capability and 3) demonstrating what can be achievable from a commercial system with respect to sensitivity, resilience, size, weight and cost.
