Abstract

Work on Z-pinches, that is under way at the SRC RF TRINITI, is aimed at the resolution of two basic problems: to investigate the problem of physics of X-ray generation in a Z-pinch scheme with the goal of its application for ICF at the "Angara-5-1" facility to develop the engineering aspects of multimegampere facilities intended for using them in a Z-pinch scheme for ICF and making the "Baikal" project. At the "Angara-5-1 facility" the measurements of plasma production rates for the wire and foam liners were taken. It has been shown that for Mo, W, Cu, Fe, and Al a current sheath with a radial thickness much larger than the skin- layer forms. The value of the plasma production rate for these metals was obtained. In the case of the liner from agar-agar foam no formation of such a layer was observed. The spectral measurements taken in hybrid Al-W liners make it possible to estimate the electron temperature and concentration from the spectrum of Al ions. It is also shown that an addition of tungsten into the array compound at a constant mass leads to a decrease of not only the electron temperature but also the final radius of stagnation. The measurements of the hard X-radiation appearing at the moment close to a peak of the X-ray pulse are likely to indicate the formation of an several kiloamperes electron beam. The experiments with conical arrays consisting of tungsten wires demonstrate the effects which arise when the wire array is imploded both in radial and axial directions. For large cone angles there appear two separate radiating regions. The corresponding X-ray pulses have a double-peak structure. Calculations of such liner compression are used to test the programs describing both radial and axial plasma compression. The results obtained at the IMM RAS fairly well provide a quantitative description of the X-ray pulse structure. Such conical liners prove to be a promising tool to test complicated RMHD codes. A pulse generation scheme relevant to the "Baikal" project is under development at the MOL facility. A 30-fold reliable current multiplication in the inductive storage has been obtained. The storage energy was effectively transferred to the subsequent stage of formation, i.e. a magnetic amplifier. The current in the latter was multiplied by a factor of 1.55. At the "Angara-5-1" facility the MEVL code reporting the process of magnetic insulation arising in the in-parallel- connected magnetically insulated vacuum lines has been tested.

“贝加尔湖”项目和“安加拉-5-1”设施的辐射z -pinch调查
SRC RF TRINITI正在进行的Z-pinch工作旨在解决两个基本问题:研究Z-pinch方案中x射线产生的物理问题,目标是将其应用于“Angara-5-1”设施的ICF,开发用于ICF Z-pinch方案和制作“贝加尔湖”项目的多尺度设施的工程方面。在“Angara-5-1设施”,测量了电线和泡沫衬垫的等离子体产生速率。研究表明,对于Mo、W、Cu、Fe和Al,会形成径向厚度远大于皮层的电流鞘层。得到了这些金属的等离子体生成速率值。在琼脂泡沫衬里的情况下,没有观察到这样一层的形成。在混合Al- w衬垫中进行的光谱测量使得从Al离子的光谱中估计电子温度和浓度成为可能。在阵列化合物中加入恒定质量的钨,不仅降低了电子温度,而且降低了最终的滞止半径。在接近x射线脉冲峰值的时刻出现的硬x射线的测量可能表明形成了几千安培的电子束。用钨丝组成的锥形阵列进行了实验,证明了钨丝阵列在径向和轴向内爆时所产生的影响。对于较大的锥角,出现两个独立的辐射区域。相应的x射线脉冲具有双峰结构。这种线性压缩的计算被用来测试描述径向和轴向等离子体压缩的程序。在IMM RAS获得的结果相当好地提供了x射线脉冲结构的定量描述。这样的锥形衬垫被证明是一个很有前途的工具,以测试复杂的RMHD代码。MOL工厂正在开发与“贝加尔湖”项目有关的脉冲产生方案。在电感存储器中获得了30倍可靠的电流倍增。存储的能量被有效地转移到形成的下一个阶段,即磁放大器。后者的电流乘以1.55倍。在“Angara-5-1”设施中,MEVL代码报告了并联磁绝缘真空线路中产生的磁绝缘过程,并进行了测试。
