AGATA, for advanced gamma tracking array, is a highly developed detector system to track gamma rays. It is a European collaboration project funded by twelve countries in Europe. The project was proposed in 2001 and in 2002 it was signed by the participant countries; in 2005 the first detector showed its result. It is expected that the complete AGATA will be ready within 2018. The spectrometer is 4π gamma-ray detector which is a combination of several Germanium detectors (Ge-detector). It is a major instrument to study nuclear structure ray tracking by measuring the . AGATA will have very good full energy peak efficiency with high peak-to-total ratio (P/T) and angular resolution. The system will be capable of high event rates with ancillary detectors to measure light charged particles or ne
