Ion trapping and laser cooling have become the techniques of choice for high-precision experiments in different branches of physics. On one hand, Penning traps have been used for nuclear-astrophysics, standard model tests, anti-hydrogen, and trace element analysis experiments. On the other hand, Paul traps have been widely used for decades for frequency standards, quantum information, and various atomic physics applications. In this talk, I will discuss an ion trap facility JYFLTRAP (1), consists mainly of three different parts: a gas cell for stopping the radioactive ions; a radiofrequency quadrupole structure for cooling, accumulating and bunching the ions; and a double Penning trap system for isobaric purification and cyclotron frequency measurements. The data were used to study neutron shell closure at N = 50 (2,3), and for Q-value measurements of double beta-decay for neutrino mass hunting (4, 5, 6). I will discuss all of these results. Also I will discuss the progress on the ion trapping experiment at Los Alamos National Lab using laser cooled single ion in a linear Paul trap and its application to precision measurements (7).
