Development of a Multi-Channel Plate Time of Flight system for the European Recoil separator for Nuclear Astrophysics (ERNA)

Novae are the result of a thermonuclear runaway (TNR) on the surface of a white dwarf star, resulting in a cataclysmic explosion and the synthesis of new elements (nucleosynthesis) up to calcium. They are also likely the source of the 6,7Li budget of the universe. The nuclear reactions which occur in the TNR involve proton capture on stable and short-lived radioative nuclei. These reactions all occur at kinetic energies well below the Coulomb barrier, meaning the reation cross sections are very small.. As a result, directly measuring their reaction rates requires creative experimental facilities with high beam intensities and extremely high background suppression.

The European Recoil separator for Nuclear Astrophysics (ERNA) in Castera, Italy, is a unique European facility designed for the direct measurements of astrophysically important thermonuclear reaction rates, satisfying the requirements of high beam intensity and high background suppression. We are now actively dveloping a scientific program at ERNA to measure nova thermonuclear reaction rates, starting with the 33S + p --> 34Cl + γ reaction, which is important for understanding the isotopic ratios of 32,33,34S in presolar grains (star dust trapped in meteorites) and gamma-ray astronomy. As part of this development, a new time of fight (TOF) detector system is planned for installation at ERNA to enhance background suppression and discrimination of fusion events.

Development of this TOF system will occur jointly at the ERNA facility itself and locally at TUM, using beams from the 14 MV tandem accelerator of the Maier-Leibnitz laboratory. Succesful development of the TOF system for a masters degree would be naturally followed by a doctoral project of measuring the 33S(p,γ)34Cl thermonuclear reaction rate at the ERNA facility.
