Rare and short lived radioactive isotopes provide unique possibility for the study of fundamental interaction and symmetries. At TRIµP different radioactive isotopes are produced in inverse kinematics mode. Dual magnetic separator is used for separating fast radioactive isotopes of interest from the primary beam. For example, 21Na are produced with a yield of 104/s/pnA(of primary beam) in the 20Ne (2H, n)21Na reaction. Produced fast radioactive isotopes are converted into low energy ion beams in thermal ionizer. This allows one to collect efficiently and transport the ions into magneto-Optical Trap (MOT) and ions are neutralized in MOT chamber. We will measure β-ν energy and angular correlation measurement in β decay for 21Na. From this measurement, deviation from the weak interaction (V-A type) can be studied. One of the other measurements which are of our particular interest is search of permanent electric dipole moment, and to improve the value for parity non conservation in Ra. Different radium isotopes have been produced in inverse kinematics. 213Ra has been produced with a typical yield of 103 /s/pnA (Pb beam) in 206Pb (12C, 5n) 213Ra reaction. A procedure to trap Ra effectively has been successfully developed by the first time trapping of Ba. Details on the facility and new technological approaches for several units of the TRIµP facility will be presented.
