Summary

19

bull The In-Gas-Jet method is being optimized to study fusion evaporation reaction products

bull IGLIS combines good efficiency and spectral resolution and is well suitedfor the study of heavy elements

bull PLIF has been implemented and can be used to characterize local flow parameters find the best nozzles for IGLIS studies

bull Considering RIS as an alternative method to characterize flow parameters (higher efficiency)

bull Commissioning of REGLIS3 at LPC Caen is ongoing A full off-line characterization of the setup along with a further optimization of the IGLIS technique are planned
