An apparatus to produce francium atoms and to trap them in a magneto-optical trap (MOT) has been set up at the Legnaro INFN National Laboratories (Italy). A detailed description of the main parts of the apparatus is given together with step-by-step measurements characterizing the production, transport, neutralization, and trapping of the radioactive atoms. The Fr MOT is operative, and the first trapping signal of the 210 Fr isotope is reported.

Abstract
An apparatus to produce francium atoms and to trap them in a magneto-optical trap (MOT) has been set up at the Legnaro INFN National Laboratories (Italy).
