Outlook Experiments at RIBF for –Decay spectroscopy with EURICA gamma-ray detector array. – Half-lives and Pn-values as part of BRIKEN collaboration setup (Beta-delayed neutrons at RIKEN). ?! Experiments at DESPEC setup in FAIR from 201X… AIDA expected to be ready for experiments by Fall BRIKEN setup

Parasitic test at RIBF Stable running of detector system under experimental conditions (10 days of beamtime). Tested data merging for full system, and clusterization algorithm. Identified issue of high noise for low amplitude range (20MeV) with BB18 sensor connected to system. Data analysis ongoing (K. Matsui, C. Griffins). Heavy ion signals (20 GeV range)
