基于康普顿背散射的10 MeV级强$γ$射线束线
An Intense $γ$-ray Beam Line of 10 MeV Order Based on Compton Backscattering
摘要:
上海激光电子γ源是最近提出的一条10 MeV量级的$γ$射线束线。在上海同步辐射装置3.5GeV储存环中,该束线将通过CO $_2$激光与电子的后向康普顿散射产生最大能量为22 MeV的$γ$ -射线。如果采用100 W量级输出功率的商用CO $_2$激光器并以优化设置注入,则非准直$γ$ -射线的通量可以是10 $^9$ $\sim$ 10 $^{10}$ s $^{-1}$。
英文摘要:
Shanghai Laser Electron Gamma Source, a $γ$-ray beam line of 10MeV order was proposed recently. The beam line is expected to generate $γ$-ray with maximum energy of 22MeV by backward Compton scattering between CO$_2$ laser and electron in the 3.5GeV storage ring of future Shanghai Synchrotron Radiation Facility. The flux of non-collimated $γ$-ray can be 10$^9$ $\sim$ 10$^{10}$s$^{-1}$ if a commercial CO$_2$ laser of 100W order output power is employed and injected with optimized settings.
