在該算法中將需規(guī)劃路徑的二維編碼簡(jiǎn)化成一維編碼。
In addition to pic method , the numerical computation method is used as a compensation for the study of the characteristics of electron beam . the two methods are used separately to attain the trajectory of axially - emitted electron beam in diode region and drift region , and the trajectory of radially - emitted electron beam with axial , azimuthal , as well as compounded axial and azimuthal magnetic field . three two - dimensional codes and two three - dimensional codes have been made out to compute the trajectories
本文特點(diǎn)之一就是采用粒子模擬和數(shù)值計(jì)算相結(jié)合的方法進(jìn)行仿真計(jì)算,分別得到了軸向發(fā)射條件下電子在二極管區(qū)域和漂移區(qū)的軌跡,徑向發(fā)射條件下電子在角向磁場(chǎng)、軸向磁場(chǎng)、角向和軸向復(fù)合磁場(chǎng)中電子的運(yùn)動(dòng)軌跡,分別編制了三個(gè)二維電子軌跡計(jì)算程序和兩個(gè)三維電子軌跡計(jì)算程序,最后將粒子模擬和數(shù)值計(jì)算得到的結(jié)果進(jìn)行了對(duì)比,得到了較為滿意的結(jié)果。
