About the Project
This PhD project will give you the opportunity to carry out some of the first physics exploitation of the DarkSide-20k dark matter observatory, a next-generation international experiment being constructed 1.4 km beneath a mountain at the Gran Sasso National Laboratory in Central Italy. DarkSide-20k will use around 50 tonnes of ultra-pure liquid argon as a target to search for the extremely rare interactions expected if particle-like dark matter passes through the detector. Following…
commissioning in 2027, it is expected to become the world's most sensitive experiment of its kind, with an operational lifetime of around a decade.
The University of Manchester and the wider UK community play major roles in DarkSide-20k. Our group leads activity in advanced photosensor instrumentation, detector simulation, AI-enabled analysis, and the development of high-fidelity digital twins of the experiment. These tools are essential for modelling possible dark matter signals, understanding backgrounds that can mimic them, and optimising the detector and analysis to maximise its discovery reach.
As the PhD student, you will:
- Contribute to the installation and commissioning of Manchester-built radiopure silicon photosensor arrays in the DarkSide-20k neutron veto system, use recorded in situ performance to improve detector simulations, and explore the potential of the highly instrumented veto system for additional physics measurements beyond its primary background-rejection role.
- Develop generative-AI digital twins trained on calibration and commissioning data to replace computationally costly detector simulations, enabling fast, high-fidelity modelling of signal and background processes and improved statistical inference.
- Develop and deploy AI-enabled real-time techniques to identify and classify low-level pulses in silicon photosensors, using unsupervised-learning and pulse-shape-discrimination techniques to separate possible dark matter interactions from noise and detector backgrounds.
- Analyse the first physics data from DarkSide-20k for a range of non-standard dark matter candidate models, using these advances to extend the experiment's discovery potential and scientific reach.
You will receive training in:
- Silicon photosensor operation and low-background instrumentation.
- Astroparticle physics and rare-event searches.
- Computational detector simulation and digital-twin development.
- Generative AI, unsupervised learning, and advanced data analysis.
- Statistical inference, high-performance computing, and scientific software.
You will join one of the UK's largest particle physics groups and become a member of both DarkSide-UK, spanning 11 institutes, and the international Global Argon Dark Matter Collaboration of around 500 scientists and engineers. You will work closely with researchers, engineers, and other PhD students in Manchester and internationally, with opportunities to contribute directly to experimental operations and collaboration activities. Subject to additional research funding, we anticipate the possibility of an extended placement at the underground experimental site in Italy.
This project will place you at the interface of experimental particle physics, AI, advanced instrumentation, and scientific computing, with the opportunity to contribute directly to one of the leading dark matter searches of the coming decade. The combination of detector, AI, simulation, and large-scale data-analysis expertise will provide strong preparation for careers in fundamental research, data-intensive science, AI, instrumentation, and wider technology sectors.
This project is expected to start in September 2027.
