摘　　要：报道了一种同步辐射光束线单色仪晶体的真空安装应力形变、热缓释方法及其实验结果 ,在总功率为 2 1 0W ,最大功率密度为 1 .2 8W/mm2 时 ,晶体形变的等效曲率半径大于 2 0 0 0m ,最大隆起高度小于 0 .1 μm .The stress distortion and a cooling method of crystal of double crystal monochromator and its experimental result are reported. The crystal, cooled by this method and exposed to the heat load of total power of 210W and the peak power density of 1.28W/mm 2, can be used for bending magnet beam line of Shanghai Synchrotron Radiation Facility.
