“ when a particle beam is directed toward a point on the surface , the gold atoms bounce off and expose the silicon layer underneath just like a hammer and chisel , “ zohar said 當粒子光束被導向于矽片表面的某一點,金原子反彈,露出底下的矽層,就像是鐵?與鑿子的作用,左哈爾說。

These results indicate that the magnetic field should have upper stability when the particle beam is low polarized while the requirement of the stability of the magnetic field can be lowered when the particle beam is high polarized in the experiment of producing the polarization of the particle beam . and the complementariness can be used as a negative feedback to stabilize the polarization of particle 這一結果表明,在產生離子束極化的實驗中,在離子束低度極化的前期階段,磁場應具有較高的穩定性,而在離子束極化度較高的后期階段,磁場的穩定性要求可以放松;自旋的縱向分量的無規漲落和橫向分量的無規漲落的互補性有可能用來做成穩定離子極化的負反饋。

With the wide application of carbon / phenolic composite in spacecrafts and missile hulls , the prediction of dynamic response or internal damage of structures subject to explosion , impact or the shock wave induced from the sediment of high - energy particle beam and the evaluation of capability of composite in defending stress wave , aroused the study of the constitutive relation and the characteristic of stress wave propagating 隨著碳酚醛在航天飛行器結構及導彈殼體中日益廣泛的應用,預測結構受到爆炸作用、沖擊或由于高能粒子束在其表層大量沉積而產生的應力波所引起的動態響應及內部損傷,以及對其防護應力波的性能進行評估等,都需要對碳酚醛的本構關系以及應力波在其中的傳播特性開展研究。

To attain the high - power , well - proportioned and steady high - energy particle beam is the base of analyzing beam loss . the factors that influence the emission performance of the filament are analyzed , and the parameters are calculated . the experiment results proved the correctness of analyses 獲得大功率、均勻、穩定的高能粒子束是進行束流損失分析的基礎,本文分析了影響燈絲發射特性因素,對燈絲各參數進行了設計計算,實驗證明了分析的正確性。

Fortunately , when a laser or charged particle beam is sent through a plasma , interaction with the plasma can create a longitudinal electric field 幸運的是,當雷射或帶電粒子穿過電漿時,與電漿的作用可創造出縱向的電場。

At first sight , laser beams and charged particle beams do not seem well suited for particle acceleration 乍看之下,雷射光束和帶電粒子束似乎并不適用于粒子加速上。

A pulse from an intense laser or particle beam , however , creates a disturbance in the plasma 然而,一個從高密度的雷射或粒子束所產生的脈沖,可以對電漿產生擾動。

The power source is not microwave radiation but is either a laser beam or a charged particle beam 能量的來源不是微波幅射,而是雷射光束或是帶電粒子束。

Charged particle beam 荷電粒子

High power laser and particle beams 強激光與粒子束
