At KVI a new facility is being set up which aims for trapping radioactive isotopes to study fundamental interactions in physics using combined atomic and nuclear physics methods. Radioactive nuclides are created with ion beams from the superconducting cyclotron AGOR in inverse kinematics and fragmentation reactions. A broad range of possible products can be separated from the primary beam in a magnetic double recoil and fragment separator system. The isotopes of interest will be slowed down in matter and further cooled, confined and bunched using a segmented radiofrequency quadrupole device. Singly charged species are guided to experimental stations. After neutralization the atoms will be optically cooled and stored in atom traps (e.g. MOTs) The research program pursued by the local KVI group includes precision studies of nuclear β-decays, through β–neutrino (recoil nucleus) correlations, parity violation in atoms and searches for permanent electric dipole moments. Commissioning of the separator facility is foreseen in the course of the year 2004, where after it will be open for use by outside scientific groups.
