高级伽马跟踪阵列（AGATA）已安装在意大利的莱尼亚罗国家实验室（LNL）。在这个装置中，AGATA将在开始时由13个AGATA三重集群（ATC）组成，角度覆盖范围为1π，并且ATC的数量将逐渐增加到2π角度覆盖范围。该装置将利用Tandem-PIAVE-ALPI加速器复合体和SPES设施提供的稳定和放射性离子束。在LNL的AGATA的新实施将用于两种不同的配置，首先是一个耦合到PRISMA大接受磁谱仪，最近的第二个在零度，沿着束线。这两种配置将使我们能够涵盖广泛的物理程序，使用不同的反应机制，如库仑激发，聚变蒸发，转移和裂变的能量接近库仑势垒。这些装置被设计为与各种互补探测器耦合，例如带电粒子探测器、中子探测器、重离子探测器、高能γ射线阵列、低温和气体喷射靶以及用于寿命测量的柱塞装置。我们在本文中提出的概念设计，特点和性能数字，这种实施AGATA在LNL。
The Advanced GAmma Tracking Array (AGATA) has been installed at Laboratori Nazionali di Legnaro (LNL), Italy. In this installation, AGATA will consist, at the beginning, of 13 AGATA triple clusters (ATCs) with an angular coverage of 1π, and progressively the number of ATCs will increase up to a 2π angular coverage. This setup will exploit both stable and radioactive ion beams delivered by the Tandem–PIAVE-ALPI accelerator complex and the SPES facility. The new implementation of AGATA at LNL will be used in two different configurations, firstly one coupled to the PRISMA large-acceptance magnetic spectrometer and lately a second one at Zero Degrees, along the beam line. These two configurations will allow us to cover a broad physics program, using different reaction mechanisms, such as Coulomb excitation, fusion-evaporation, transfer and fission at energies close to the Coulomb barrier. These setups have been designed to be coupled with a large variety of complementary detectors such as charged particle detectors, neutron detectors, heavy-ion detectors, high-energy γ-ray arrays, cryogenic and gasjet targets and the plunger device for lifetime measurements. We present in this paper the conceptual design, characteristics and performance figures of this implementation of AGATA at LNL.
