Abstract

A new detector system for measurements of charged particles and

γ

-rays in coincidence has been developed at TIFR Mumbai, by coupling an annular double-sided segmented Si detector with an array of Compton-suppressed clover HPGe detectors. Digital data acquisition system has been configured for the setup, which has been calibrated and tested using the ²²⁹Th radioactive source that emits

α

-particles along with

γ

-rays. The functionality and performance of the coincidence apparatus for Doppler correction of

γ

-transitions emitted during the in-flight de-excitation of the projectile and the target in the ³⁰Si + ¹⁹⁷Au Coulomb excitation experiment have been demonstrated.

在 TIFR 开发用于核结构和反应研究的带电粒子-γ 重合系统

通过将环形双面分段硅探测器与康普顿抑制三叶草 HPGe 探测器阵列耦合在一起，孟买 TIFR 开发出了一种用于测量带电粒子和 γ 射线重合的新型探测器系统。已为该装置配置了数字数据采集系统，并使用 229Th 放射源对其进行了校准和测试，该放射源在发射 γ 射线的同时还发射 α 粒子。在 30Si + 197Au 库仑激发实验中，对射弹和目标在飞行中去激发过程中发射的 γ 转变进行多普勒校正的巧合装置的功能和性能已经得到证明。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
