N2 - A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2015β2018 at βπ = 13 TeV from ππ collisions corresponding to an integrated luminosity of 139 fbβ1are examined. Particles producing anomalously high ionization, consistent with long-lived spin-Β½ massive particles with electric charges from |π| = 2π to |π| = 7π are searched for. No statistically significant evidence of such particles is observed, and 95% confidence level cross-section upper limits are calculated and interpreted as the lower mass limits for a DrellβYan plus photon-fusion production mode. The least stringent limit, 1060 GeV, is obtained for |π| = 2π particles, and the most stringent one, 1600 GeV, is for |π| = 6π particles.
