使用二维粒子模拟研究了自生磁场中的无碰撞韦伯不稳定性介导的激波（Kato和Takabe，Astophys. J. Lett. 681，L93（2008））。据预测，韦伯激波的产生需要使用NIF级高功率激光系统。使用Gekko XII激光系统在逆流等离子体中产生无碰撞静电冲击（Kuramitsu等人，物理修订信函106，175002（2011））。批准了一个NIF设施时间方案，以研究无碰撞韦伯激波的形成。OMEGA和OMEGA EP实验已经开始研究使用汤姆逊散射的NIF实验所需的逆流等离子体的等离子体条件，并开发质子射线照相诊断。
A collisionless Weibel-instability mediated shock in a self-generated magnetic field is studied using two-dimensional particle-in-cell simulation (Kato and Takabe, Astophys. J. Lett. 681, L93 (2008)). It is predicted that the generation of the Weibel shock requires to use NIF-class high-power laser system. Collisionless electrostatic shocks are produced in counter-streaming plasmas using Gekko XII laser system (Kuramitsu et al., Phys. Rev. Lett. 106, 175002 (2011)). A NIF facility time proposal is approved to study the formation of the collisionless Weibel shock. OMEGA and OMEGA EP experiments have been started to study the plasma conditions of counter-streaming plasmas required for the NIF experiment using Thomson scattering and to develop proton radiography diagnostics.
