Two types of DD neutron energy spectrometer (NES) are under development for deuterium plasma operation in KSTAR to understand behavior of beam ions in the plasma. One is based on the state-of-the-art nuclear emulsion technique. The other is based on a coincidence detection of a recoiled proton and a scattered neutron caused by an elastic scattering of an incident DD neutron, which is called an associated particle coincidence counting-NES. The prototype NES systems were installed at J-port in KSTAR in 2012. During the 2012 and 2013 experimental campaigns, multiple shots-integrated neutron spectra were preliminarily obtained by the nuclear emulsion-based NES system.
为了了解韩国超导托卡马克先进研究装置(KSTAR)中氘等离子体运行时束流离子的行为,正在开发两种类型的DD中子能谱仪(NES)。一种基于最先进的核乳胶技术。另一种基于对入射DD中子弹性散射产生的反冲质子和散射中子的符合探测,这被称为关联粒子符合计数-NES。NES原型系统于2012年安装在KSTAR的J端口。在2012年和2013年的实验期间,基于核乳胶的NES系统初步获得了多次 shots-integrated 中子能谱。
