The Columbia University Astrophysics Laboratory invites applications for a Postdoctoral Research Scientist position in experimental atomic physics. The project is entitled “Fe IX Line Survey and Density Sensitivity Studies in Support of the NASA Heliophysics Program”. The successful candidate will join the group of Drs. Daniel Wolf Savin and Michael Hahn. The experimental work will be carried out using the EBIT-I electron beam ion trap located at the Lawrence Livermore National Laboratory (LLNL) in Livermore, CA. The research is being carried out in collaboration with the groups of Dr. Greg Brown at LLNL and Dr. Peter Beiersdorfer at the University of California Berkeley. The successful candidate will be appointed at Columbia, but will be based at LLNL. The appointment will be initially for one year, with the possibility of renewal for up to two additional years; this is contingent upon the availability of funds and mutual satisfaction. The successful candidate will have a Ph.D. or equivalent degree in Physics, Applied Physics, or a related discipline. Desired laboratory skills include single particle/photon detectors and the associated electronics; magnetically guided electron beams; understanding of accelerator physics; EUV, UV, and optical spectrometers; EBITs; and ultrahigh vacuum systems. Desired computer skills include programming, multidimensional data analysis, LabView, IGOR Pro, Autodesk Inventor, SIMION, Python, IDL, Linux/Mac OS, and Windows OS. The successful candidate will have a strong background in at least some of the areas listed above, a proven research ability, and evidence of future research potential. They are expected to be able to work well independently and cooperatively with a team and to communicate the results of their research both orally and in writing. Demonstrated written and oral communication skills are highly desirable. Questions regarding this position can be addressed to Dr. Savin at [email protected]. Applicants should submit a cover letter, curriculum vitae (including a list of publications) and statement of past research. In addition, they should arrange to have three letters of reference sent directly by the writers to Dr. Savin. Applications will be considered only after all of the requested material has been received. Applications can be submitted via email to [email protected]. Screening of applicants will begin immediately and will continue until the position is filled. Columbia is an Equal Opportunity Employer/Disability/Veteran Employer.
