本文报道了能量为4 MeV/u的氩离子穿透完全电离的碳等离子体的能量损失和射弹电荷态的测量结果。用波长为532 nm的两束激光从两个相对侧面入射到薄碳箔上，产生了n（e）约为10（20）cm（-3），T-e约为180 eV的等离子体。产生的等离子体是空间均匀的，使我们能够记录精确的实验数据。数据显示，在阻止功率的一个因素的增加是非常好的协议与专门开发的蒙特卡罗代码，允许计算的重离子束的电荷状态分布和它的能量损失在等离子体中。DOI：10.1103/PhysRevLett.110.115001
This Letter reports on the measurement of the energy loss and the projectile charge states of argon ions at an energy of 4 MeV/u penetrating a fully ionized carbon plasma. The plasma of n(e) approximate to 10(20) cm(-3) and T-e approximate to 180 eV is created by two laser beams at lambda(Las) = 532 nm incident from opposite sides on a thin carbon foil. The resulting plasma is spatially homogenous and allows us to record precise experimental data. The data show an increase of a factor of 2 in the stopping power which is in very good agreement with a specifically developed Monte Carlo code, that allows the calculation of the heavy ion beam's charge state distribution and its energy loss in the plasma.
