用K壳层X射线能谱研究了小质量铜箔靶(>；20x20x2微米；{3})与高强度(>；10；{19}wcm；{2})激光脉冲的相互作用。利用循环快电子的碰撞能量转移，可以有效地加热到200 eV以上。用三维数值模拟计算的K光子产额和体电子温度与实验测量结果吻合较好。
K -shell x-ray spectroscopy is used to study the interaction of small-mass copper foil targets (>20x20x2microm;{3}) with a high-intensity (>10;{19}Wcm;{2}) laser pulse. Efficient bulk heating to greater than 200eV is demonstrated using collisional-energy transfer from recirculating fast electrons. K -photon yields and bulk-electron temperatures calculated by three-dimensional numerical target-heating simulations are in good agreement with the experimental measurements.
