During the search of the new element Z = 119, the GARIS-III setup also initiated its transition to a digital electronics solution using the PIXIE-16 modules. The implementation of this solution and the overall improvement of the performance and preliminary results will be presented in this talk. The reduction of the overall deadtime of the setup and a preliminary analysis of the pulse shape will be detailed.
Recently, we also started to use a lighter surrogate reaction to study the effect of the side collision configuration based on a target with a similar deformation to 248-Curium using the 51-Vanadium beam. The main goal was to extend the systematic studies of 51-Vanadium reactions and side collision effects on deformed targets. The first measurement was performed using a 159-Terbium target and has produced both the barrier distribution and a precise excitation function.
