大功率电子辐照加速器X射线具有较强的穿透能力,应用于食品保鲜、医疗灭菌、工业材料改性等领域,能够弥补电子束辐照穿透能力弱的缺点。X射线转换靶是利用高能电子束轰击高Z材料产生X射线。电子打靶产生X射线的效率低约10%,较多功率沉积在转换靶上,导致转换靶产热率较高。因此在X射线转换靶设计中,冷却结构 High-power electron radiation accelerator X-ray has strong penetrating ability, and is applied to the fields of food preservation, medical sterilization, industrial material modification and the like, and can make up for the weak penetration ability of electron beam irradiation. X-ray conversion target is the use of high-energy electron beam bombardment of high-Z material to produce X-rays. Electron-targeting produces X-rays less than about 10% less efficiently, and more power is deposited on the conversion targets resulting in higher heat transfer rates. Therefore, in the X-ray conversion target design, the cooling structure
