The International Workshop on Positron Studies of Defects (PSD-24)

Following a standing tradition that began in 1987 in Germany, The International Workshop on Positron Studies of Defects (PSD-24) was held in the Sala Bianca of the Teatro Sociale di Como, Italy, from September 1 to 6, 2024.The workshop aimed to provide a platform for the exchange of the latest scientific results and developments concerning positron interactions with solids and surfaces, the applied techniques, and their diverse applications. An intensive two-day Summer School in honour of Alfredo Dupasquier was held at the Brunate Library on August 31st and September 1st, prior to the PSD-24. The School featured lectures delivered by leading international experts in Positron Annihilation Spectroscopy (PAS).
