Popis: We describe the realization of a dark spontaneous-force trap of rubidium atoms. The atoms are loaded from a beam provided by a two-dimensional magneto-optical trap yielding a capture efficiency of 75%. The dense and cold atomic sample is characterized by saturated absorption imaging. Up to \( {10}^9 \) atoms are captured with a loading rate of \( 3\times {10}^9 \) atoms/s into a cloud at a temperature of 250 \( \mu \)K with the density exceeding \( {10}^{11} \) atoms/cm\( {}^3 \). Under steady-state conditions, more than 90% of the atoms can be prepared into the absolute atomic ground state, which provides favorable conditions for the investigation of sympathetic cooling of ions in a hybrid atom–ion trap.
