摘要
In 2016,the total operation time is 6 500 h,including 4 500 h for experiments,740 h for ion source tuning and beam changing,400 h for machine preparation and beam waiting at the site.The percentages for these activities mentioned are 69%,11%and 6%.The failure time is 900 h,accounting for 14%of the running time,and this value is at the highest level in years.37%of the experimental time was contributed to IMP,11%was to institutes other than IMP,47%to universities and 5%to enterprises(shown in Fig.1).Among the research purpose,71%of the experimental time was for material research,20%for atomic and molecular dynamics,9%for plasma physics,nuclear astrophysics,and atom and molecular spectroscopy(presented in Fig.2).
