| 摘 要： | 利用六波长瞬态光学高温计测量了"神龙一号"加速器发射的高能电子束与靶材作用后靶受作用区的温度变化过程。获得了厚度为0.1~0.25mm的Ta,Al和Cu片靶与强流电子束作用后的温度变化过程,最高温度接近9000K,达到了温密物质区域。实验结果表明,利用"神龙一号"加速器发射的强流电子束与特定靶材作用可以获得可供观测的温密物质,而多波长瞬态光学高温计是测量这种温密物质的温度变化的有效手段。

| Abstract: | Abstract:The electron beam generated by the Dragon-Ⅰlinear induction accelerator struck the target, and an instantaneous optic pyrometer with six working wavelengths was used to measure the temperature process of beam-target interaction region. The thicknesses of targets were 0.1-0.25 mm. Temperature processes of tantalum, aluminum and copper target stricken by strong electron beam were acquired. The highest temperature was up to approximately 9000 K, it reached the region of warm dense matter. The experiment results show that the observable warm dense matter can be acquired by means of the electron beam generated by the Dragon-Ⅰlinear induction accelerator striking specifical targets, and the instantaneous optic pyrometer with multi-working wavelengths is an effective instrument for measuring temperature of the warm dense matter. |
