快重离子辐照固体材料在线紫外可见光发射测量平台

An Experiment Platform for in situ Study of Ultraviolet Visible Emission from Solid Irradiated by Swift Heavy Ions

快重离子辐照固体材料是个复杂的物理过程,涉及大量粒子发射过程,包括紫外可见光发射。为了研究快重离子辐照过程中紫外可见光发射,在兰州重离子加速器(HIRFL)中能辐照终端SFC-T1搭建了快重离子辐照固体材料光发射测量平台。利用该实验平台,可在线获取不同能量和不同电荷态的快重离子辐照固体材料过程中发射的紫外可见光谱,有助于加深理解快重离子在固体材料中的辐照效应物理机制。对于进一步结合辐照后微结构分析开展核用材料辐照损伤的研究做了展望。

Swift heavy ion irradiation of solid materials is a complicated physical process involving a large number of particle emission processes,including ultraviolet visible emission.In order to study the ultraviolet visible light emission from solid induced by fast heavy ion,a measurement platform for swift heavy ion irradiation solid was built in the medium energy irradiation terminal SFC-T1 of Lanzhou heavy ion Accelerator(HIRFL).The ultraviolet-visible spectra from solid irradiated by swift heavy ions with different energy and charge states can be obtained online at this experimental platform,which is helpful to deepen the understanding of the physical mechanism of swift heavy ions irradiation effect in solid materials.Further research on radiation damage of nuclear materials combined with microstructure analysis after irradiation is prospected.
