A novel type of gaseous ionization detector—Optical Time Projection Chamber (OTPC)—developed to study rare nuclear decays is presented. The OTPC records tracks of charged particles ionizing a counting gas by optical imaging of the light generated by electrons multiplied in the amplification structures. By combining an electron drift-time profile measured by a photomultiplier and a CCD camera image we reconstruct three-dimensional trajectories of particles, energies and charges. The capabilities of the OTPC detector to study various decay modes are demonstrated by observation of beta-delayed proton emission from 13O, two-alpha break-up of 8Be, triple-alpha decay of 12C excited states and two-proton radioactivity of 45Fe.
