为了满足日益增多的重离子辐照的要求,同时改进重离子辐照的辐照质量,决定在R20管道上建立支线,成为专用重离子辐照管道。1束流线基本要求束流线基本要求为:重离子注量率为102～106s-1·cm-2可调;辐照面积为10cm×10cm;离子种类为C～Au。以Au为例,能量为300MeV的Au30+,在10cm×10cm面积上,以102～106s-1·cm-2的注量率辐照时,要求加速器提供的束流强度为0.5fA～5pA,通常串列加速器在稳定状态下最小只能提
In order to meet the increasing requirements of heavy ion irradiation, while improving the irradiation quality of heavy ion irradiation, it is decided to establish a branch line on the R20 pipeline and become a special heavy ion irradiation pipeline. A beam line basic requirements Beamline requirements: heavy ion fluence rate of 102 ~ 106s-1 · cm-2 adjustable; irradiation area of 10cm × 10cm; ion species C ~ Au. Taking Au as an example, Au30 + with an energy of 300MeV is required to irradiate the beam with an intensity of 0.5fA to 5pA at a fluence of 102 to 106s-1 · cm-2 on a 10cm × 10cm area, Tandem accelerator in the steady state can only mention the minimum
