[Neutron] Position as instrument scientist for a novel high intensity cold neutron spectrometer at NIST

[Collin Broholm]

NIST CENTER FOR NEUTRON RESEARCH 

NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY 

The NIST Center for Neutron Research (NCNR) is seeking expressions of
interest in a position as instrument scientist for a novel cold neutron
spectrometer. Required qualifications are a Ph. D. in experimental Condensed
Matter Physics. Experience in neutron, X-ray, or light scattering is
desirable as is an interest in scientific instrumentation and software
development. The Multi Analyzer Crystal Spectrometer (MACS) features a
doubly focusing monochromator and a twenty channel detection system (see
http://www.pha.jhu.edu/~broholm/MACS). These innovations will yield two
orders of magnitude greater sensitivity than a conventional triple axis
spectrometer for probing localized or slowly propagating excitations in hard
condensed matter. The instrument is being developed in a partnership between
NIST, Johns Hopkins University, and NSF. The successful candidate will
participate in the commissioning phase for MACS, which will include software
development and optimizing strategies for data acquisition on this new type
of spectrometer. This effort will transition into development of a wide
ranging scientific program that takes advantage of the high sensitivity of
MACS. The scientific program will include inelastic magnetic scattering
experiments on quantum magnets, strongly correlated electron systems, and
artificially structured solids as well as diffuse scattering experiments to
probe polarons and other static or dynamic nano-scale phenomena in condensed
matter. This work will be carried out in close collaboration with Prof.
Collin Broholm from Johns Hopkins University. From the fall of 2006, MACS
will welcome external users at which point there will be an opportunity to
collaborate with and help a wide range of users with experiments on MACS.
Appointments will be for several years. The salary will be competitive and
will depend on qualifications and experience. 

Letters expressing interest in such a position along with a resume and
contact information for three references should be sent to:
