美国布鲁克黑文国家实验室2020年招聘博士后（同步加速器/x射线）

The National Synchrotron Light Source-II (NSLS-II) at Brookhaven National Laboratory is seeking exceptional candidates for a beamline scientist position within the Complex Scattering Program at NSLS-II to support operations and perform research at the Complex Materials Scattering (CMS) and Soft Matter Interfaces (SMI) beamlines. Based on a high-brightness undulator source, the SMI beamline enables the exploration of novel types of hierarchical ordering and heterogeneities in frontier materials by providing advanced x-ray scattering capabilities in tender and hard x-ray ranges, including grazing- incidence and transmission small- and wide-angle x-ray scattering (GI)SAXS/WAXS, resonant scattering, and liquid-interface scattering. Based on a three-pole-wiggler source, the CMS beamline facilitates efficient exploration of complex materials in vast material parameter spaces by providing high-throughput and streamlined (GI)SAXS/WAXS capabilities. Through their complementary capabilities, the CMS and SMI beamlines together enable state-of-the-art research for a user community with wide research interests covering both soft and hard materials and a variety of applications, including in-situ studies during advanced manufacturing processes and mechanical testing, polymeric and nano-composite materials, liquid and solid interfaces, novel nanomaterials, complex fluids, liquid crystals, biomaterials, and materials for energy conversion and storage.

Position Description：

Working together with beamline scientists, data analysis scientists, beamline technicians and engineers, and other support staff, the successful candidate will support the user program and beamline operations at the CMS and SMI beamlines. The candidate will also develop an independent science program and scientific collaborations, which intersect with the CMS and SMI capabilities. The candidate will be placed at the appropriate scientific level dependent upon depth and breadth of relevant knowledge and skills the candidate brings to the position, as well as the amount of relevant experience.

Essential duties:

Support of the CMS and SMI beamlines: beamline development, operations and user programs;

Development of an independent research program and opportunities for internal and external scientific collaborations that leverage the unique capabilities of the beamlines;

Interact with the scientific user community and work with the Complex Scattering Program staff to help grow user programs for x-ray scattering and execute technical developments needed to facilitate the growth.

Position Requirements：

Required Knowledge, Skills, and Abilities:

Ph.D. in materials science, physics, chemistry, or a related field.

At least two (2) years of postdoctoral or equivalent experience associated with activities at synchrotron x-ray or neutron scattering beamlines.

Experience in the collection and analysis of small- or wide-angle scattering data.

Experience and an extensive publication record in polymer science research based on x-ray or neutron scattering.

Excellent written and oral communications skills.

Demonstrated experience and ability to work effectively with a multidisciplinary team of scientists, engineers, technical support staff, and users.

Preferred Knowledge, Skills, and Abilities (One or more of the following):

Prior experience with grazing-incidence scattering (GISAXS/GIWAXS), x-ray reflectivity, and/or liquid-interface scattering.

Prior experience with in-situ studies of materials, especially under processing conditions.

Prior experience with 2D detectors and related data analysis.

Programming skills for data reduction and analysis in Python.

Prior experience with designing instruments or sample environments.

Other Information: The position classification offered will be commensurate with the candidate’s depth and breadth of experience.
