报告人简介：

Dr Sergey Danilkin completed his M.Sc. in materials science and solid-state physics at the Moscow Institute of Physical Engineering in 1974. He then went to work at the Institute for Physics and Power Engineering (Obninsk) in Laboratory of Neutron Spectroscopy performing experiments with time-of-flight spectrometer DIN-2 at the pulsed reactor in Dubna, Russia.

Sergey Danilkin received his PhD in experimental physics from the Joint Institute for Nuclear Research (Dubna) in 1986, studying the lattice dynamics of light interstitial atoms in transition metals. Immediately prior to joining ANSTO, he was instrument scientist for a 3-Axis Spectrometer at the Hahn-Meitner Institute, Berlin, Germany. 

In August 2004, Dr Sergey Danilkin joined ANSTO to lead the efforts on installation and development of the TAIPAN thermal-beam 3-Axis Spectrometer at the OPAL reactor. His current research interests include inelastic neutron scattering study of superionic conductors and thermoelectric materials.

报告摘要：

In the talk I will give a short overview of neutron facility at OPAL reactor at ANSTO with special emphasis on thermal triple-axis spectrometer TAIPAN, its design, performance and recent experimental results.

Thermal triple-axis spectrometer TAIPAN was the first instrument for inelastic neutron scattering built at the new Australian research reactor OPAL. The TAIPAN started operation in February 2009 and is in full user service since November 2010. The basic description of design and parameters of TAIPAN are given in papers [1, 2]. First experiments on TAIPAN were performed with superionic conductor Cu _2−xSe and published in 2010 year [3, 4].

Resent experimental results on phonons in superionic and thermoelectric materials with high performance will be presented including the copper selenide and SnSe. I will give a short overview of recent investigations of HT superconductors performed by users from China.
