Electron tubes continue to provide the highest speeds possible for recording dynamics of hot high-energy density plasmas. Standard streak camera drive electronics and CCD readout are not compatible with the radiation environment associated with high DT fusion yield inertial confinement fusion experiments >10 14 MeV DT neutrons or >10 n cm ns. We describe a hardened x-ray streak camera developed for the National Ignition Facility and present preliminary results from the first experiment on which it has participated, recording the time-resolved bremsstrahlung spectrum from the core of an inertial confinement fusion implosion at more than 40× the operational neutron yield limit of the previous National Ignition Facility x-ray streak cameras.
电子管仍然能够为记录高温高能量密度等离子体的动力学过程提供可能的最高速度。标准的条纹相机驱动电子设备和电荷耦合器件(CCD)读出方式与高氘-氚(DT)聚变产额惯性约束聚变实验(产生大于10^14兆电子伏特的DT中子或大于10个中子/厘米²·纳秒)所涉及的辐射环境不兼容。我们描述了一种为国家点火装置开发的加固型X射线条纹相机,并展示了它参与的首次实验的初步结果,该实验记录了惯性约束聚变内爆核心的时间分辨轫致辐射光谱,其运行中子产额超过了国家点火装置先前X射线条纹相机的40倍以上。
