【摘要】：SSW(Solar SoftWare)的能量電子產(chǎn)生X光子的軔致輻射積分計算發(fā)展到版本2時,其性能相比初始的版本1提高很多.在版本2的基礎(chǔ)上,對這個積分進一步改進.通過對比幾種軔致輻射積分方案,結(jié)果顯示,最終的方案性能上比版本2可以快約2～5倍.在積分的精確性上比版本1及版本2均改進了很多,在缺省的積分控制精度下也不再產(chǎn)生光子譜的尖刺現(xiàn)象.而且,積分耗時不再敏感于積分上限取值.由于積分性能的提高,使得利用精確的軔致輻射截面計算軔致積分成為可能.結(jié)果顯示,用精確軔致輻射截面比先前的近似截面積分的結(jié)果光子流量略小(≤4%),積分時間大約比先前使用近似截面多30%.
[Abstract]:The Bremsstrahlung integral (Bremsstrahlung integral) of energy electrons produced by energy electrons of SSW Solar Software has been developed to version 2, and its performance is much higher than that of the original version 1. This integral is further improved on version 2. By comparing several Bremsstrahlung integral schemes, the results show that the performance of the final scheme is about 2 or 5 times faster than that of version 2. The accuracy of the integral is much better than that of version 1 and version 2, and the pinching of photon spectrum is no longer produced under the default integral control precision. Moreover, the integral time consuming is no longer sensitive to the upper value of the integral. Due to the improvement of integral performance, it is possible to calculate the Bremsstrahlung integral by using accurate Bremsstrahlung cross section. The results show that the photon flux with the exact Bremsstrahlung radiation cross section is slightly smaller than that of the previous approximate cross section (鈮，
