激光产生的质子束已被用于实现固体密度的碳样品的超快体积加热。碳的等容熔化是通过二次激光产生的等离子体的x射线散射来探测的。从散射信号，我们推导出的材料，被熔化的不均匀加热的分数。结果进行比较，不同的理论方法的状态方程，建议从标准模型的修改。
Laser-produced proton beams have been used to achieve ultrafast volumetric heating of carbon samples at solid density. The isochoric melting of carbon was probed by a scattering of x rays from a secondary laser-produced plasma. From the scattering signal, we have deduced the fraction of the material that was melted by the inhomogeneous heating. The results are compared to different theoretical approaches for the equation of state which suggests modifications from standard models.
