A study of Prof Tomoya Yamauchi and Associate Prof Masato Kanazaki on solid-state track detectors has been published in the international journal ‘Radiation Measurements’.
The title is "Isolated radiation damage created along un-etchable tracks in PADC consists of two hydroxyl groups ".

PADC is a transparent polycarbonate thermoset and an etched track detector with high sensitivity. Energetic protons or heavy ions create nano-sized damage along their path in it, and etching creates etch pits that can be observed under an optical microscope. This research has elucidated the damage structure that does not produce etch pits, providing essential knowledge for the development of detectors with higher detection sensitivity.
Professor Yamauchi and his colleagues have long collaborated with the University of Strasbourg and the National Institute for Quantum Science and Technology QST Institute for Radiological Science, but this work was carried out in collaboration with the QST Takasaki Institute for Advanced Quantum Science and the Inter-University Program for the Joint-use of JAEA/QST Facilities, Nuclear Professional School, School of Engineering, the University of Tokyo.
