Dear Rietvelders, Necsa (South African Nuclear Energy Corporation) is seeking candidates for the following two positions in the field of neutron and X-ray diffraction. We are looking for experienced scientists with practical hands-on experience and a record of diffraction based research. POSTIONS IN X-RAY AND NEUTRON DIFFRACTION The Diffraction Group from the Research and Development Division of Necsa provide X-ray and neutron diffraction (at the SAFARI-1 Research Reactor) facilities for user access. All laboratories are currently being upgraded and expanded, to meet the needs of the South African scientific and engineering research fraternities. A key element is the expansion of the scientific expertise base through the attraction of skilled individuals to become technical experts in support of the user communities. We are looking for suitable candidates to fill the following two positions: 1. POSITION: SCIENTIST/ENGINEER (Residual stress / texture) The candidate will be responsible to lead visiting scientists with their material science related research topics in residual strain/stress and texture analyses using X-ray and neutron diffraction. Duties involve both technical and scientific tasks associated with the development of the new neutron diffraction instrument, operation and use of both instruments, collaboration/participation with scientific user programs, as well as theoretical modeling/validation of results. Job Description: * Technically responsible for the X-ray strain scanner (Bruker D8 Discover with GADDS) with co-responsibility on the development and running of the new 2nd generation neutron strain scanner. * Leading and collaborating with visiting scientists/students in their user programs at the facilities. * Development of new experimental equipment, capabilities and ancillaries to fulfill user requirements. * Establishment of theoretical models based on finite-element methods to validate/predict results. Person Profile: The successful applicant should comply with the following education, experience and skills requirements: * At least MS or PhD in Physics or Mechanical Engineering. * Practical skills and keen interest in instrumentation/facility development. * 3 -5 years hands-on experience with strain / texture investigations with diffraction techniques. * Proven experience in conducting independent research. * Ability to function in a multi-disciplinary environment and teach understudies. * Medically fit for registration as a radiation worker. 2. POSITION: SCIENTIST (X-ray and neutron powder diffraction) The candidate will be responsible to lead visiting scientists with investigations of chemical and magnetic related research topics using X-ray and neutron diffraction. Duties involve both technical and scientific tasks associated with the development of the new neutron diffraction instrument, operation and use of both instruments, collaboration/participation with scientific user programs, as well as theoretical assessment with Rietveld methods. Job Description: * Technically responsible for the running of the X-ray powder diffraction instrument with co-responsibility on the development and running of the new neutron powder diffraction instrument. * Leading and collaborating with visiting scientists/students in their user programs at the facilities. * Development and application of ancillaries such as 3.5K cryostat and 1500K furnace on the neutron instrument to fulfill user requirements. * Establishment of theoretical models based on finite-element methods to validate/predict results. Person Profile: The successful applicant should comply with the following education, experience and skills requirements: * At least MS or PhD in Physics/Chemistry/Geology. * Practical skills and keen interest in instrumentation/facility development. * 3 -5 years hands-on experience with Rietveld techniques and powder diffraction. * Proven experience in conducting independent research. * Ability to function in a multi-disciplinary environment and teach understudies. * Medically fit for registration as a radiation worker. Location: Necsa Limited, Pretoria, South Africa. More information and detailed resumes to be sent to: Andrew Venter: Tel: +27 12 305-5038; e-mail: [EMAIL PROTECTED]
