<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-size:12.0pt; line-height:115%; font-family:"Times New Roman","serif"">Dear Colleagues,
</span></p>
<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-size:12.0pt; line-height:115%; font-family:"Times New Roman","serif"">Helmholtz Zentrum Berlin and European Spallation Source Project are pleased to announce the workshop on “Perspectives
in Terahertz Spectroscopy with Neutrons” to be held on November 29-30, 2011 in Helmholtz Zentrum Berlin, Germany.
</span></p>
<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-size:12.0pt; line-height:115%; font-family:"Times New Roman","serif"">The workshop will bring together young and experienced scientists who are using or planning to use neutron terahertz
spectroscopy for their research. The scope of the event is to address the new application directions and answer the questions: what are the important scientific issues to be addressed by help of neutron TOF spectroscopy.
</span></p>
<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-size:12.0pt; line-height:115%; font-family:"Times New Roman","serif"">The unique feature of neutron scattering is that it delivers direct microscopic information in both space and
time, while other spectroscopic probes are either local (such as hyperfine field methods) or macroscopic in the spatial dimension (such as light scattering). Time-of-Flight (TOF) spectroscopy with cold neutron allows us best to explore phenomena in condensed
matter on the terahertz frequency range (10</span><span lang="EN-US" style="font-size:12.0pt; line-height:115%; font-family:Symbol">m</span><span lang="EN-US" style="font-size:12.0pt; line-height:115%; font-family:"Times New Roman","serif"">eV -150meV) and
on a length scale from 0.5 to 100 Å . This method can be applied to study extremely broad range of phenomena in complex systems, e. g. quantum phenomena in magnetism, microscopy dynamics of proteins, and fast ionic diffusion in conducting systems. The high
data rates and new instrumental capabilities of modern spectrometers open up new opportunities for systematic, in situ and kinematic investigations or study of excitation spectrum of complete Brillouin zones. Direct neutron spectroscopic measurements in the
space and time domain allow us to benchmark and validate molecular dynamic model calculations forming a very powerful tool in exploring nanoscale dynamics and functionality.
</span></p>
<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-size:12.0pt; line-height:115%; font-family:"Times New Roman","serif"">The program will include sessions on soft matter, magnetism, and material science. An overview of new trends
in neutron TOF spectroscopy instrumentation and data handling and interpretation approaches will also be presented.
