Status of the TRIμP project

At KVI the technical structures for the TRIμP facility are nearly all in place. The aim of the project is to use radioactive ions to study fundamental interactions and symmetries. We will measure β-recoil correlations in nuclear β decay. There the V,A structure of the Weak interaction may be violated. The second line of research is the search for a permanent electric dipole moment in Ra, with a magnitude forbidden by the Standard Model. By trapping these radioactive nuclei in atom traps a pure sample that can be manipulated facilitates these searches. The TRIμP facility consists of a production target and magnetic separator on the high energy side and a Radio-Frequency Quadrupole (RFQ) cooler and buncher on the low energy side. An ion catcher stops the fast product nuclides and transport them into the RFQ cooler. New technological approaches were implemented for several of these devices.
