Working at MIT offers opportunities, an environment, a culture – and benefits – that just aren’t found together anywhere else. If you’re curious, motivated, want to be part of a unique community, and help shape the future – then take a look at this opportunity.
POSTDOCTORAL ASSOCIATE, Nuclear Reactor Lab (NRL), to join the MIT Research Reactor (MITR), the primary experimental facility of Nuclear Reactor Laboratory and one of five U.S High-Performance Research Reactors. MITR is developing high-efficiency neutron diffractometers suitable for both large national neutron facilities and small university research reactors and building a novel high-resolution neutron diffractometer. Unlike existing powder and engineering diffractometers, which operate with monochromatic beam, MITR will use polychromatic beam and multiple bent perfect crystal analyzers. The use of the polychromatic beam will allow combining several analyzers to increase the signal rate or allow to measure several components of the stress tensor at once. Will participate in all aspects of the instrument building, testing, and demonstration. The work will include finalizing the design, assembling instrument components (focusing analyzers, position-sensitive detectors, oscillating collimators, etc.), enabling the instrument-control software, testing, and commissioning of the facility. MITR is also designing a focusing SANS diffractometer which will use axisymmetric focusing mirrors (Wolter mirrors) to enable a compact SANS instrument suitable for a university-based research reactor. This project will require ray-tracing optimization of the design parameters of the mirrors and other beam-conditioning optics and conducting initial tests.
REQUIRED: Ph.D. in nuclear engineering, mechanical engineering, physics, or another related field; Interest and experience in hands-on experimentation with neutron or X-ray diffraction or small-angle scattering; solid understanding of neutron diffractometers inner workings; and the ability to keep to schedules and deadlines and to work effectively both as a team member and independently. Job #19518
