We report the magnetic trapping and evaporative cooling of bosonic and fermionic isotopes of atomic chromium. Using a cryogenic helium buffer gas, 10 1 2 chromium atoms are trapped at an initial temperature of ∼ 1 K. The chromium atoms are then cooled adiabatically and evaporatively to temperatures as low as ∼10 mK. Elastic and inelastic 5 2 Cr collisional cross sections are measured over this temperature range. Prospects for simultaneously creating a 5 2 Cr Bose-Einstein condensate and 5 3 Cr Fermi degenerate gas will he discussed.
