The Short Baseline Neutrino Detector (SBND) at Fermilab is a 100 ton liquid argon detector that is part of a suite of three new detectors based on new technology using liquid argon, sited in a neutrino beam at Fermilab. Sheffield has played a leading role in construction of this new experiment, including contributing to design and construction of the main Anode Plane Arrays (APAs). SBND is due to start full operation in 2018/19. The project will focus on analysis of data in the area of searches for sterile neutrino events and the relationship to the dark matter problem. This includes development of LARSOFT simulations. There will be opportunity to contribute to final installation activities, detector optimization and operation. The project offers a rare chance in neutrino physics to gain experience of both detector hardware and operation as well as data analysis towards new physics. There will be chance for long term attachment (6-12 months) in Chicago, Fermilab.
