primary beam energy

基本解释

The simulation results for a pin point electron beam show that a good resolution corresponds to lower values of primary energy, detection energy windows and detection angle.
点源模型的模拟结果显示小的入射能量、探测能量窗口及探测角值对应较好的分辨率。
The propagation characteristics of laser beam in underground air medium were studied, primary causes of the laser energy decaying in the underground were explored theoretically and practically.
