介绍了在"阳"加速器上使用的闪烁体功率计结构和测量参数,讨论了功率计在北京同步辐射装置上的标定实验,分析了标定结果及由此结果可能给最后实验结果带来的误差,并探讨了修正该误差可行的办法,利用 Dante谱仪测得的能谱对功率计测试结果进行修正.修正后,两套设备之间的测试结果差异由原来的30%以上降至15%以内.最后给出了利用软X光闪烁体功率计进行喷气Z箍缩等离子体辐射测量的结果,得到"阳"加速器上喷气Z箍缩负载产生的软X光辐射峰值功率为几十GW,能量产额数百J.

This paper presents the configuration and measuring parameters of scintillator power meter applied in Z-pinch plasma soft X-ray yield measurement on Yang accelerator. It also introduces the calibration experiment on BSRF, and analyzes the defect of the power meter from calibration results, the possible errors and feasible method for correcting the errors. The measuring results are revised according to spectrum acquired from Dante spectrometer. The revised discrepancy of two instruments is decreased from over 30% to subter-15%. Finally, the result of yield measurement of the puff Z-pinch X-ray radiation is reported as well, i.e., hundreds of Joule, multigigawatt levels of soft X ray radiation were produced by puff Z-pinch on Yang accelerator.
