A compact, quasi-4pi position sensitive silicon array, TIARA, designed to study direct reactions induced by radioactive beams in inverse kinematics is described here. The Transfer and Inelastic All-angle Reaction Array (TIARA) consists of 8 resistive charge division detectors forming an octagonal barrel around the target and a set of double-sided silicon-strip annular detectors positioned at each end of the barrel. The detector was coupled to the -ray array EXOGAM and the spectrometer VAMOS at the GANIL Laboratory to demonstrate the potential of such an apparatus with radioactive beams. The 14N(d,p)15N reaction, well known in direct kinematics, has been carried out in inverse kinematics for that purpose. The observation of the 15N ground state and excited states at 7.16 and 7.86 MeV is presented here as well as the comparison of the measured proton angular distributions with DWBA calculations. Transferred l-values are in very good agreement with both theoretical calculations and previous experimental results obtained in direct kinematics.
Development and characterization of a large area silicon pad array for an electromagnetic calorimeter
我们目前的研究和开发工作的第一个版本的6*6阵列的硅垫探测器，在印度进行，为拟议的前向量热计（FOCAL）的ALICE合作升级计划的一部分，在欧洲核子研究中心。主要的动机是开发一个大面积的硅垫阵列实现高能量物理实验的挑战性要求，如低漏电流，高击穿电压，并评估其性能作为原型硅钨（Si-W）电磁（EM）量能器中的有源层。为了实现这些目标，在班加罗尔的Bharat Electronics Limited，在4英寸高电阻率N型晶片上设计了一个36焊盘的硅传感器，其单个焊盘尺寸为1 cm 2。该传感器已被用于组装原型硅钨量热计，并成功地与高能粒子束测试。本文报道了大面积硅传感器的设计、研制及其在实验室用放射源和高能粒子束上的特性。
