Development of nuclear pumped lasers (NPL) in the CFBR-Ⅱ reactor is briefly reviewed. The results ofthe two NPL experiments in CFBR-Ⅱ reactor are described. The first one focused on the principle ofnuclear pumped laser, and 4-mW laser output power achieved. The second NPL experiment focused onthe small signal gain and the efficiency of the nuclear pumped He-Ar-Xe gas mixture at 1.73 μm. Themaximum laser power measured to be 45 mW when thermal neutron flux rate is 6.9 × 10 14 cm-2 @ s-1.The small signal gain at 1.73μm by the Rigrod analysis method is to be 0.24%.cm-1, and the saturationintensity is fitted to be 36 W/cm2. 相似文献

新建堆厅的密封包容性检测 总被引:1,自引:0,他引:1
新建堆厅必须具有很好的密封包容性,即对放射性气溶胶具有小的泄漏率(常压下约10^-2/d;超压保持约1h,超压情况下的泄漏率是常压下的约10倍)。在堆厅建造完成后,用实验来检验其是否满足设计要求。采用工程模拟性的SF6气体作为示踪剂对3个堆厅的密封包容性进行了检测,该方法是研究气体扩散、混合、渗漏及泄漏和传输等气体动力学特征的有效方法。SF6气体示踪检漏的基本原理是在堆厅内具有所需压力后,在堆厅内迅速释放一定量的SF6气体,然后将堆厅内取样点处的气样通过管道直接引入气相色谱进样系统, 相似文献
