Line 4A's Instrument
Scientist is Valeria Lauter. Valeria received her PhD in Experimental and Theoretical Solid State Physics from the Joint Institute for Nuclear Research in Dubna, Russia. Her previous work has been as a Research Scientist at the Technical University of Munich, Germany; Research Scientist at the University of Konstanz, Germany; Visiting Scientist at the Institute Laue-Langevin in Grenoble, France; Research Scientist at the Laboratoire de Magnetisme CNRS in Grenoble, France; and Staff Scientist at the Joint Institute for Nuclear Research in Dubna, Russia.
During her many years of experience in neutron scattering Valeria focused on reflectometry, off-specular scattering, and grazing incidence small angle scattering (GISANS) with polarized and unpolarized neutrons. Her professional experience in these fields covers both instrumentation and the physics of low-dimensional systems. The field of Valeria's scientific research includes magnetic and non-magnetic nano-scale materials, magnetic anisotropy, interlayer coupling, GMR, interfacial structure, formation of domains, magnetisation reversal, determination of layer-by-layer magnetisation distribution, domain structure, self-organised organic structures with incorporated magnetic nanoparticles, high temperature superconducting films, smart films.
In instrumentation Valeria's professional skills are related to the development, construction, commissioning and performing experiments on time-of-flight and monochromatic reflectometers.

Line 4A's postdoctoral
scientist is Haile
Ambaye. Haile
received a B.S. and
M.S. in Physics from
Addis Ababa University,
Ethiopia. His masters
research was done at
the Forschungszentrum
Juelich, Germany under
a scholarship granted
by the German Academic
Exchange Service (DAAD). Haile
earned his PhD in Physics
from Clemson University
before joining the
SNS magnetism reflectometer
group in 2006. Previous
areas of research include
understanding and developing
theoretical models
for molecular scattering from
metal surfaces (rotational
and vibrational energy
exchange channels),
transport processes
in disordered media
and bio-medical optics
(laser detection of
anomalous tissue growth).

Line 4A's scientific
associate is Rick Goyette,
who has over nineteen
years experience supporting
reflectometers and
their users. Rick has
a B.S. and an M.S.
in Physics from the
University of Rhode
Island, and is a Red
Hat Certified Engineer. Prior
to coming to SNS Rick
spent sixteen years
at the Intense Pulsed
Neutron Source where
he supported both the
polarized and un-polarized
reflectometers as well
as the single crystal
diffractometer and
two computer networks.
