  At the Kernfysisch Versneller Instituut (KVI) in Groningen, NL, a new
facility (TRI$\mu$P) is under development. It aims for producing, slowing down
and trapping of radioactive isotopes in order to perform accurate measurements
on fundamental symmetries and interactions. A spectrum of radioactive nuclids
will be produced in direct, inverse kinematics of fragmentation reactions using
heavy ion beams from the superconducting AGOR cyclotron. The research programme
pursued by the KVI group includes precision studies of nuclear $\beta$-decays
through $\beta$--neutrino (recoil nucleus) momentum correlations in weak decays
and searches for permanent electric dipole moments in heavy atomic systems.
This offers a large potential for discovering new physics or to limit
parameters in models beyond standard theory significantly. The scientific
approach chosen in TRI$\mu$P can be regarded as complementary to such high
energy physics. The facility in Groningen will be open for use by the worldwide
community of scientists.
