Based on the potential resonance in heavy - ion collisions, the anomalous phenomenon of the backward - angle oscillatory arising in the angular distribution for 16o + 12c elastic scattering have been studied within the framework of the optical model using a deep optical potential
摘要基於重離子碰撞中勢共振的考慮,在光學模型的框架下,使用深光學勢研究了16o + 12c彈性散射角分佈后角振蕩上升的反常現象。To make pic ( particl - in - cell ) simulations. to set up models of guns and magnetic field and simulate them in the vacuum and plasma, respectively. we found that plasma held back part of space charge effects and improved trajectory of electrons. but beam would oscillate and became instable as accretion of plasma density. by simulating again and again, we draw a conclusion magic could n ' t work when plasma density was more by far than beam electron density. at last a four - stage depressed collector was simulated
建立電子槍和聚焦系統模擬模型,分別在真空和填充等離子體條件下進行模擬。發現填充等離子體能補償部分空間電荷效應,改善電子束包絡軌跡,提高電子的流通率,但是隨著等離子體密度的增大,束電子會出現振蕩不穩定性,遺憾的是通過反復多次模擬發現本文所用粒子模擬的代表性軟體magic無法用於模擬等離子體密度遠高於束電子密度的情況。Theoretical model of self - mixing interference in a linear frequency modulated laserdiode is presented by using the dynamic theory of semiconductor laser with weak external optical feedback. the characteristics of oscillation frequency shift and output power changes of the laser diode are analyzed by using the theoretical model. the absolute distance from front facet of laser diode to target can be found by measuring spectrum of output power of the laser diode
