Abstract:

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 0.01μW•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.
