摘  要：激光同步輻射源能產(chǎn)生準(zhǔn)單色、能量可調(diào)的超短脈沖X射線，它將在醫(yī)學(xué)、生物、材料等很多科學(xué)領(lǐng)域得到廣泛的應(yīng)用。

　　　本文對(duì)激光同步輻射源的特性和國(guó)內(nèi)外一些激光同步輻射源裝置的實(shí)驗(yàn)參數(shù)進(jìn)行了分析，主要內(nèi)容分為以下幾個(gè)部分：

1.首先用康普頓散射理論分析了激光同步輻射源的原理，討論了激光同步輻射源光子的最大能量，散射截面和散射能譜。

2.分析了激光同步輻射源的特性，包括考慮和不考慮激光束和電子束的橫向分布對(duì)散射光子產(chǎn)額的影響時(shí)散射光子通量，實(shí)驗(yàn)裝置的接收角、電子束能散、角發(fā)散、激光束角發(fā)散和帶寬對(duì)散射X光單色性的影響以及X射線的時(shí)間結(jié)構(gòu)。在這里考慮了電子束和激光束的發(fā)散度的影響，這是大部分文獻(xiàn)沒(méi)有考慮的。

3、上海應(yīng)用物理研究所正在研制ps、fs直線加速器，考慮可以利用它開展激光同步輻射源研究，分析了可能達(dá)到的性能。國(guó)內(nèi)外的多家科研機(jī)構(gòu)也在這一領(lǐng)域里開展了理論和實(shí)驗(yàn)研究，用我們得到的關(guān)于激光同步輻射源的特性理論分析了這些實(shí)驗(yàn)的性能，提出了優(yōu)化的條件。

Abstract：The laser synchrotron source (LSS) configuration was proposed to be used as an effective way of producing tunable, short pulse, near-monochromatic X-ray source for many medical and material science applications. Experiments have been proposed to study and implement similar configuration at many institutions.

　　Theory and properties of laser synchrotron source and experimental parameters of some domestic and aboard laser synchrotron source facilities have been investigated in this paper. It includes the following sapects:

1.first compton scattering theory for analyzing LSS was reviewed, which is including the energy of scattering photons、scattering section、scattering energy spectrum and the relations between them .

2.main properties of LSS, including X-ray flux,、time structure of pulse and energy spectrum are calculated and discussed. The impact of transverse distribution of electron and laser beams in the interaction area is took into account.

3.Based on the facilities of ps 、fs electron linacs and ns、fs high-power lasers which are now building in shanghai institute of applied physics, we calculate the based properties of these LSS facilities. properties of other domestic and aboard LSS falities are also calculated and we get the sililar compared with the given results. We also simply analyse the optimum experimental conditions.
