摘　　要：引进了美国GAMMA公司的高精度数字式可调标准光源RS-5B,并对其性能参数进行了测试。结果表明,该光源光强空间分布非常稳定,在光强大于0.001μW.cm 2时,复位性优于1%;在光强大于0.01μW.cm 2时,稳定性优于0.5%。其输出光强与标称值呈线性分布关系。这些优良的参数和特性满足聚变物理标定研究中对标定源的需求,为物理实验数据分析和计算模拟提供了条件。The high-precision digital light source RS-5B from GMMA company was introduced and its performance parameters was measured. The results show that the spatial distribution of light intensity is very stable. When light intensity is stronger than 0.001μW-cm-2, the resettability better than 1% and when stronger than 0.01μtW-cm-2, the stability better than 0.5%. The output light intensity and nominal value keep the linear relationship. These excellent parameters and characteristics meet the demands of the calibration source in the calibration test of fusion research and meanwhile provide the conditions for experiment data analysis and computer simulation.
