How the NEUWAVE workshop series has pushed neutron imaging developments

ABSTRACT

In 2008, a series of international workshops—named NEUtron WAVElength-dependent Imaging (NEUWAVE)—was initiated after several decisions were taken to build new neutron spallation sources in the world, namely target station two of ISIS in the UK, J-PARC in Japan, SNS in the US, and the future ESS, now being built in Sweden. The aim was to collect existing knowledge about energy-dependent effects in neutron imaging, but also to develop new energy-selective imaging methods for the upcoming spallation sources, and also for steady-state sources using energy selecting devices for neutrons. The special format was a workshop with plenty of discussions but without explicit publications, where participants discussed not their past work, but their ideas and future plans. This paper gives a résumé after nine such meetings and highlights the most important progress features. The series will continue in 2019 with NEUWAVE-10 to be organized by Paul Scherrer Institut.
