The tutorial presents the Bo2022 database, a tool that collects - and will continue to collect in the future - Padua's academic population over the eight centuries of its history. The research project BO2022,from which this database was born, began in 2019 and ended in February 2021, and one of its aims was to map the academic population from the foundation of the University of Padua, in 1222,...
Fundamental processes related to negative ion formation by

Twenty years ago, there was no ion source that could provide high-currents (>20 mA) of H- beams at high duty factors (>>1%). In addition, the lifetime of H- sources was limited to ~2 Amp-hours. Therefore high-duty-factor H- sources had to be replaced every few weeks! The H- ion sources limited...
