September 7 to 11, 2020, Tokyo Institute of Technology, Tokyo, Japan

Registration Registration fee Announcements Important Dates abstract submission

History of covariance workshop:

This workshop is the fifth one in a series, started 2008 in Port Jefferson, USA by BNL, and continued in 2011 in Vienna, Austria by the Vienna University of Technology, hosted in 2014 in Santa Fe, USA by LANL and in 2017 in Aix en Provence, France by CEA. The CW2020 workshop is planned to take place at Tokyo Institute of Technology (Tokyo Tech.), Tokyo, Japan during September 7-11, 2020, one month after the 2020 Tokyo Olympic game.

Purpose of CW2020:

The purpose of this workshop is to bring together key scientists in the field of nuclear data measurement and evaluation, statistical analysis, nuclear reaction theory, reactor physics, and other relevant applications to review recent developments in nuclear data evaluation methodology where uncertainty quantification is involved, to assess and discuss open questions, and to exchange our ideas and expertise relevant to the covariance data. This opportunity will be particularly important for identifying areas of future cooperation amongst the participants. The workshop scope is open to contributions on a wide variety of nuclear data observables (cross sections, fission yields, energy and angle spectra, etc.), from the resonance range up to high energy range as well as for light to heavy elements.


The workshop will take place at the Multi-Purpose Digital Hall in the west area of Tokyo Institute of Technology, Ookayama, Tokyo, Japan. http://www.dst.titech.ac.jp/outline/facility/hall_en.html
