Research Associate - Experimental Nuclear Astrophysics

The Facility for Rare Isotope Beams (FRIB) is a major new scientific user facility for nuclear science, funded by the Department of Energy Office of Science (DOE-SC), Michigan State University (MSU), and the State of Michigan, with operations supported by the DOE-SC Office of Nuclear Physics. FRIB will provide intense beams of rare isotopes (that is, short-lived nuclei not normally found on Earth). FRIB will be operational in 2022. Presently, experiments are performed at MSU at the National Superconducting Cyclotron Laboratory (NSCL) supported by the National Science Foundation. NSCL accelerates stable and long-lived rare isotopes. FRIB and NSCL will continue to enable scientists to make discoveries about the properties of these rare isotopes in order to better understand the physics of nuclei, nuclear astrophysics, fundamental interactions, and applications for society.

At FRIB, rare-isotopes beams will be produced and separated in-flight, and subsequently thermalized and reaccelerated to energies up to 6 MeV/u, by the ReAccelerator facility ReA3, a worldwide unique, state-of-the-art accelerator for rare-isotope beams. An upgrade to higher energies (ReA6) is presently under construction. Presently stable and long-lived rare isotopes are accelerated at NSCL. When FRIB comes online, it will provide the highest possible intensity rare isotope beams as input to the ReA facility.

This position affords an exciting opportunity to become part of the world-class FRIB Laboratory, and to get in on the ground floor of an emerging scientific user facility that will expand nuclear science into a whole new realm of possibility.

Position overview

NSCL invites applications from outstanding candidates for a fixed-term research associate (postdoctoral researcher) position in the area of experimental nuclear astrophysics, who will work in the research group led by Professor Chris Wrede (wrede@nscl.msu.edu).

Major position responsibilities

The successful candidate will have the unique opportunity to make major contributions to designing, building, commissioning, and running the first scientific experiments with, the Particle X-ray Coincidence Technique (PXCT) detection system for nuclear astrophysics. PXCT will use various solid-state detector technologies to measure radiations (X-rays, gamma rays, protons, and alpha particles) associated with the electron-capture decays of proton-rich nuclides in FRIB’s thermalized rare-isotope beam area. The data will be used to constrain the energies, spins, parities, lifetimes, and branching ratios of unbound states: The ingredients needed to determine the rates of key thermonuclear reactions and photodisintegrations in explosive astrophysical environments such as supernovae and X-ray bursts on accreting neutron stars. These rates will be used to simulate astrophysical observables associated with nucleosynthesis and/or energy generation in collaboration with the Joint Institute for Nuclear Astrophysics – Center for the Evolution of the Elements (JINA-CEE). Opportunities will also be available to contribute to experiments using other systems including the Gaseous Detector with Germanium Tagging TPC (GADGET II) at FRIB and the Doppler Shift Lifetimes 2 (DSL2) setup at TRIUMF.

Qualifications

Required

  • PhD in nuclear physics, nuclear and radiochemistry, nuclear astrophysics, or related field
  • Ability to carry out independent and original research as demonstrated by published work in refereed journals and/or conference proceedings

  • Strong research interest, demonstrated in the cover letter, in at least one and preferably several of the following areas: Nuclear detector developments, simulations of experimental setups, data analysis and interpretation, and digital data acquisition
  • Ability to work with export-controlled technologies

Desired

  • Demonstrable knowledge of experimental principles and techniques pertaining to nuclear spectroscopy involving charged-particle, gamma-ray, and/or X-ray spectroscopy
  • Experience with semiconductor radiation detectors
