The first muX collaboration Meeting is organised at PSI on Monday November 5, 2018. The aim of the collaboration meeting is to discuss the main aspects of the developments done since the beginning of the muX project in 2015 and the future upgrade plans. Special emphasis will be put on the plan of hosting Miniball at PSI during 2019. In this respect the Miniball collaboration and the nuclear spectroscopy community are warmly invited to participate to the meeting and present ideas for possible measurements which go beyond the muX experimental programme. Open slots have been reserved in the Discussion section for presenting new proposals. Please send an email in case you have a contribution.
