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.
點源模型的模擬結果顯示小的入射能量、探測能量窗口及探測角值對應較好的分辨率。
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.
