Prof. Uwe Greife's group at
the
Colorado School of Mines is part of
the Subatomic Physics group
in the Physics Department.
Currently the research group is pursuing the
following three activity streams:
1) Nuclear astrophysics with
radioactive ion beams (RIB): we are performing RIB experiments,
predominantly radiative capture in inverse kinematics, at the
facilities of TRIUMF (ISAC, DRAGON) and ORNL (HRIBF, DRS). In
preparation for the future where transfer reactions will play a larger
role, we are designing and building a gas jet target system for
deployment at the above mentioned facilities as well as at NSCL/FRIB.
The reactions pursued are usually relevant to nucleosynthesis on the
proton rich side of the chart of nuclides.
2) Neutron induced reactions
relevant to nuclear energy and non-proliferation issues: we are
developing experimental equipment (time projection chamber and dual arm
spectrometer) and approaches for precision measurements of fission
cross sections and fragment distributions as well as for neutron
scattering experiments. These activities are using the LANSCE neutron
beam facilities of LANL.
3) Nuclear diagnostic development
for the National Ignition Facility (NIF): the uniqueness of the time
structure as well as energy/density conditions in the nuclear burn of
ignition experiments at NIF requires creative approaches to the
diagnostics characterizing variables and outcomes. Our group is
involved with the development of a Cherenkov detecor for gamma flash
detection, neutron time of flight experiments as well as evaluations of
catcher geometries and materials for radiochemical analysis of the burn
debris.
The uniting element in all our
efforts is instrument development, which we try to apply to all fields
where our involvement is beneficial. A strong component at our state
university is naturally dedicated to education through the involvement
of undergraduate and graduate students in the research enterprise.
