On the path to fusion, nuclei dissipate their initial kinetic energy into internal excitation, but the understanding of how energy dissipation during the collision affects the resulting fusion cross-sections is still limited. To investigate energy dissipation in fusion, we are developing a new detector array that measures charge, mass, angle, and excitation energy of scattered particles, called MANTEIS (Multi-ANgle Time and Energy Identification Spectrometer). This detector performs measurements of reflected flux as a function of angle for a given beam energy. These measurements enable us to determine how the projectile and target charge, mass and kinetic energy distributions evolve as nuclei approach each other — effectively measuring the evolution and mechanism of energy dissipation. Here we present the performance and current status of the new detector array.
