Dr. Tremsin has been working on research and development of new
technologies in position sensitive photon, electron and neutron
counting detectors based on microchannel plates. Dr. Tremsin has
performed fundamental research into the development of new event
counting detection systems with unique combination of very high
spatial and temporal resolution capable of operation at very high
counting rates exceeding 500 MHz with no readout noise. These
detection systems enable novel non-destructive testing techniques
in materials research, astrophysics, synchrotron instrumentation,
biological imaging, space and ground-based observations, nuclear
energy, studies of cultural heritage objects and many others. The
high efficiency neutron detectors with no readout noise and very
low background are widely used now at various experimental
facilities around the world and several of those systems have been
installed at the user facilities at the DOE laboratories (ORNL,
LANL) and Rutherford Appleton Laboratory in the UK. The new
non-destructive testing techniques with neutrons developed by Dr.
Tremsin enable high resolution studies through energy-resolved
neutron imaging in a wide range of energies, from cold to
epithermal neutrons. Mapping of elemental composition, temperature
and even gas pressures through neutron resonance absorption,
simultaneously with studies of crystallographic properties through
Bragg scattering has been enabled by these novel fast neutron
counting detectors and data analysis methods, developed recently
by Dr. Tremsin. During his career Dr. Tremsin has also
worked on the development of new detection technologies for the
future NASA astrophysical missions, with some of these novel
devices successfully flown on multiple NASA astrophysical
missions. Dr Tremsin was also active in promoting science to the
public by lecturing at various events, including annual Cal Day,
Acalanes and Campolindo High Schools as well as serving as a Grand
Award Judge at Intel International Science Fair. In addition
to his fundamental research activities Dr. Tremsin serves as a
reviewer of many scholar journals and serves at many review panels
for various government agencies and has been named as a best
reviewer in several of them.
