We have constructed a magneto-optical trap for chromium atoms. Using trapping light at 425 nm and two repumping lasers tuned to intercombination transitions, over 106 atoms were trapped and average densities of over 1016 m-3 were obtained. Non-exponential loss of atoms is observed at high densities indicating inelastic collisions between trapped atoms. Over a range of trapping conditions, the density-dependent trap loss rate constant β is extracted from fluorescence decay curves and found to have values in the range of 10-15m3s-1,much larger than is observed in alkali traps.
