Abstract We have developed an enriched 40K source used in 40K--87Rb atomic mixture cooling experiment. The enriched 40K source is a home-made dispenser which releases 40K atoms by the redox reaction between 40K enriched KCl and calcium. It is efficient and easy to be made and used. We collect 107 ～108 40K atoms in collection magneto-optical trap. With this dispenser, we perform a quantum degenerate Fermi gas experiment.
