Outlook
To exploit the present and future facilities fully and most efficiently, advanced instrumentation and detection equipment is required – NuPECC recommendation
The 4p-array of highly segmented Ge detectors AGATA for g-ray detection and tracking is part of this effort
First measurements in-beam and with sources show that the position resolution is ~ 5 mm FWHM; this value is in line with the design assumptions of the AGATA spectrometer, confirming the feasibility of g-ray tracking
AGATA will have a strong impact on nuclear structure studies : lifetime measurements of nuclear states down to fs, angular distribution and polarization measurements
Is AGATA or part of it of interest for the ELI project?
