摘要: 肖特基（Ｓｃｈｏｔｔｋｙ）精密质量谱仪，是建立在ＧＳＩ所（当今核研究的领导所）电子冷却存储环（ＥＳＲ）上的精密质量谱仪，它对轻中量核与重核的测量精度Δｍ／ｍ分别达到５×１０－６，和５×１０－７．该谱仪为非阻挡型极灵敏的，甚至可测出一个裸核的测量设备，是冷却存储环束流诊断的可靠仪器，又是一台作核反应和核谱学研究的精密质量测定的谱仪． A Schottky precise mass spectroscope in lightmedium and in heavier nuclei with the mass resolution of Δm/m=5×10^-6　　　　　　　　　　　　　　　　　　or 5×10^-7, respectively,has been successfully built up and operated well at ESR ( Experimental Storage Ring cooled by electron beam) in G SI,the leading nuclear research institute.The spectroscope is anonstop of the beam type with quite sensitive,even one nucleus can be measured,setup that is a beam diagnosis relia ble instrument for the cooling beam in ESR...
