Title: AGATA: The European HPGe tracking array

Abstract

The future experiments on {gamma} spectroscopy need more advanced detection techniques than those typically used for stable beams. In fact, very often the studied nucleus is characterized by very high velocity (up to relativistic energy) and the conditions on the background must be very severe. The next generation detector arrays, consequently, require unprecedented levels of efficiency and sensitivity. A completely new technology on {gamma}-rays detection based on digital electronics, electrically segmented HPGe and {gamma}-ray tracking is needed. Monte Carlo simulations suggest that an HPGe array based on such techniques will have a high photopeak efficiency over a broad energy range (larger than 35% for single (1 MeV photons and larger than 20 % for a cascade of 30 photons of {approx} 1 MeV energy), combined with an excellent peak-to-total ratio (of the order of 55%). The European array based on such technology, AGATA, will be briefly presented together with the first in beam tests of segmented detectors.
