JUNO scien­tists discuss es­tablis­hing a giant neut­ri­no ob­ser­va­to­ry in the Py­hä­sal­mi mine

At their most recent meeting, the European members of the Jiangmen Underground Neutrino Observatory (JUNO) discussed the possibility of establishing a next-generation giant neutrino observatory in the Pyhäsalmi mine. This subject is relevant in the context of the update of the European Strategy for Particle Physics scheduled for 2019. European members of JUNO held a meeting at the University of Jyväskylä 17–19 October 2018.

The idea to establish the neutrino observatory in the Pyhäsalmi mine was part of the concluding session, where the status and perspectives of scientific projects in the Pyhäsalmi mine were presented and discussed. Other meeting topics included JUNO-related physics and software, photo-sensors and electronics, scintillator issues and the Top Tracker.

Around 40 physicists from Italy, France, Germany, the Czech Republic, Slovakia, Russia and Finland took part in the JUNO meeting at the University of Jyväskylä. The previous JUNO meeting in Finland took place in October 2015. During both meetings the participants have visited the Pyhäsalmi mine.

International collaboration

JUNO is a medium-baseline reactor neutrino experiment, which was constructed in Southern China with the aim of determining the neutrino mass hierarchy and performing precision measurements of the Pontecorvo–Maki–Nakagawa–Sakata matrix elements. European scientists contribute significantly to this international effort, which currently involves over 500 scientists from 72 institutions in 17 countries.

The JUNO-Eu meeting was organised by the Accelerator Laboratory of the Physics Department at the University of Jyväskylä (http://www.jyu.fi/hendes ) together with INFN Milan (http://www.mi.infn.it/en/ ) and chaired by Gioacchino Ranucci (INFN) and Wladyslaw H. Trzaska (JYU). The event was co-sponsored by the Kerttu Saalasti Institute (http://www.oulu.fi/ksi-eng/ ) and Callio Lab (https://callio.info ).
