高功率激光和电子束的汤姆逊散射是高场区电动力学的一个很好的测试方法。我们在布鲁克海文国家实验室加速器测试设施演示了二氧化碳激光和60兆电子伏特电子束正面碰撞产生的高强度x射线。在线性（最低阶）汤姆逊散射中，x射线光子的能量被限制在6.5 keV，但非线性（高阶）过程产生更高能量的x射线。我们测量了高能x射线的角度分布，并证实了它与理论预测相符。
Thomson scattering of high-power laser and electron beams is a good test of electrodynamics in the high-field region. We demonstrated production of high-intensity X-rays in the head-on collision of a CO2laser and 60-MeV electron beams at Brookhaven National Laboratory, Accelerator Test Facility. The energy of an X-ray photon was limited at 6.5 keV in the linear (lowest order) Thomson scattering, but the nonlinear (higher order) process produces higher energy X-rays. We measured the angular distribution of the high-energy X-rays and confirmed that it agrees with theoretical predictions.
