In February 2023 Dr Marek Walczak and PhD student Theo Hugues had a scientific trip to Mexico City. The reason for such a long journey was to attended DEAP-3600 collaboration meeting, where scientists were presenting status of the experiment, discussing issues and plans. Our colleagues have presented AstroCeNT’s work on the Inelastic Boosted Dark Matter search in the DEAP-3600 experiment.
