The ‘Spectroscopy Decay Fission’ team at IJCLab, Orsay, invites applications for a postdoctoral researcher to spearhead the development and commissioning of the SIRIUS detection system. Funded by the D-SHEXI ANR grant, the role involves leading the SHEXI upgrade of SIRIUS for improved L X-ray detection, enabling unambiguous identification of superheavy elements. The successful candidate will also participate in commissioning SIRIUS at the RITU separator in Finland, with potential extended stays, and is expected to propose an experimental program post-commissioning. Additional responsibilities include data analysis of 217Pa experiments to study single-particle energies and residual interactions beyond 208Pb. The position requires expertise in silicon detectors, front- and back-end electronics, C++/ROOT programming, and collaboration with teams at IPHC, GANIL, and CEA-Saclay.
