摘要
北京大学6MV串列静电加速器上建成4条束流输运线,加速~1H,^(12)C,^(16)O,^(19)F,^(35)Cl,^(79)Br等离子,并开展物理实验研究。首次利用D(^(12)C,p)^(13)C核反应建立起高灵敏度的氘分析法;利用共振核反应~1H(^(19)F,αγ)^(16)O分析材料中氢的深度分布;用重离子背散射分析超导材料YBa_2Cu_3O_(7-x);用35MeV^(35)Cl和45 MeV^(79)Br的弹性前冲分析不同材料中的轻元素及测定低能重离子的阻止本领等。
Four beam lines are constructed for the 6MV Tandem Accelerator of Peking University.Various ions such as ~1H, ^(12)C, ^(16)O, ^(19)F, ^(35)Cl, ^(79)Br, etc. are accelerated. Some experiments are made, such as deuterium determination for the first time by the D(^(12)C, p)^(13)C nuclear reaction,hydrogen profiling using the resonance reaction ~1H(^(19)F, αγ)^(16)O, backscattering analysis for highT_c superconductor YBa_2Cu_3O_(7-x), ERDA induced by 35 MeV of ^(35)Cl and 45 MeV of ^(79)Br ions foranalyzing of light elements in various materials and stopping power measurements of low energyheavy ions and other experiments.
