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 10^7 -10^8 ^40K atoms in collection magneto-optical trap. With this dispenser, we perform a quantum degenerate Fermi gas experiment.展开更多
