Final announcement

The 4th Japan-China Joint Workshop on Positron Science (JWPS 2019) will be held on October 28 to November 2, 2019 at Nara Kasugano International Forum IRAKA, Nara, Japan. JWPS 2019 is organized by Kyoto University under the auspices of the Japanese Positron Science Society.
The workshop will gather scientists of the Asian area at the forefront of research on positron annihilation to share information on recent progress in this field. The main topics include a wide range of subjects involving fundamental aspects, applications as well as instrumentation. Keynote speakers will introduce subjects of broad interest, and stimulate discussions. Plenty of time will be assigned to each presentation and informal style discussions to promote the exchange of information and ideas.
Scientific Scope
  1. Positron Physics and Positronium Chemistry
  2. Positron Applications in Metals , Semiconductors, Superconductors, and Magnetic Materials
  3. Positron Applications in Porous media, Polymers, Membranes, and Biomaterials

About JWPS
The first workshop, JWPS2012, was held in November 2012 at Wuhan University, Wuhan, China, and aimed to gather together scientists working in China and Japan at the forefront of research on positron science in order to share information on the most recent progress in relevant fields. One year later, a second workshop, JWPS2013, was held at the National Institute of Advanced Industrial Science and Technology (AIST), in Tsukuba, Japan. The latest one, JWPS 2017, was held on June 9–11, 2017 at University of Science and Technology of China (USTC), Hefei, China. These China-Japan joint workshops provide valuable opportunities for exchanging ideas and the discussion of a wide range of subjects including positron science, material science developed/analyzed by positron techniques, and measurement techniques, etc. In particular, the workshops provide a good opportunity to promote international exchange between young researchers in positron science, thus making an important contribution to the future development of this research field.
