the study of nucleon structure. Both positions will be divided between the experimental programme at Jefferson Laboratory (JLab) in Virginia, USA, and R&D for the Electron-Ion Collider (EIC), to be built at Brookhaven National Laboratory in New York state, USA.
The JLab focus of the two RA positions will be on the experimental programmes of Halls A and B, respectively. The focus for the Hall A position will be the upcoming high Q2 nucleon form factor programme with the Super Bigbite Spectrometer (SBS). This will involve installation and commissioning of the detector systems, development of dedicated data analysis and simulation software, and making a significant contribution to the day-to-day running of this challenging experimental programme. The project in Hall B will focus on experiments using the CLAS12 spectrometer, as part of the CLAS collaboration, which will start taking data with a longitudinally polarised target in 2022. It will include data-taking (shifts manning the experiment), quality-checks and calibrations, simulations, data-analysis and preparation of data for publication, as well as the writing of the associated papers and collaboration documents. There’s scope for contributions to the development of particle / event reconstruction software and preparation of proposals.
The EIC project is currently going through a detector proposal preparation stage. The half of both RA positions which is dedicated to the EIC will be a combination of detector design and optimisation using Geant4-based simulations, including the addition of new detectors to the simulation framework, evaluation of the sensitivity of the EIC towards different processes and potentially development of generators. There is scope for hardware work on a detector prototype.
The research projects will involve close collaboration with colleagues in other institutes, including Paris-Saclay, France, where one of the project leaders (Daria Sokhan) is currently on leave as Blaise Pascal Chair.
The successful candidates should have an experimental background in hadron, nuclear or particle physics and familiarity running simulations and analysing data. The successful candidates will also be expected to contribute to the formulation and submission of research publications and research proposals and help manage and direct these complex and challenging projects as opportunities allow.
