We report the fast accumulation of up to 1 million 52Cr metastable atoms in a mixed trap formed by the superposition of a quadrupolar magnetic trap and a strongly confining optical trap. The cloud is at a temperature of 100 μK with a peak density of 1018 atoms/m3, which is a promising starting point to reach quantum degeneracy by forced evaporation in an optical trap.
