Outline of Final Research Achievements

This work aimed at the trap of radioactive atoms such as francium in an optical lattice formed by the interference of laser beams. Francium will be produced via the nuclear fusion reaction, ionized by the surface ionization, transported as an ion beam, converted to neutral atoms, and cooled in a magneto-optical trap. Finally the cooled francium will be trapped in the optical lattice.
In this work, a signal in synchronization with a sequence of the francium-trap experiment was achieved. In order to make sure this signal, experimental components have been developed individually. As a result, their abilities and performances have been improved.
