Target material, and method and device for preparing target material

The invention relates to a target material, and a method and a device for preparing the target material. The target material comprises a back lining tube and a target material body. The target material body is formed on the outer surface of the back lining tube; the target material body comprises two end sections and a middle section; the thickness of a first target material of each end section islarger than that of a second target material of the middle section. According to the technical scheme, the target material, the method and the device have the advantages that the thicknesses of the end sections of the target material body are increased, the consumed durations of the target material can be prolonged in use procedures, accordingly, the problem that two ends of an existing target material body are used up at first can be solved, and the utilization rate of the target material can be increased. 本发明是关于种靶材、靶材制备方法及装置。该靶材包括：背衬管；形成于背衬管的外表面的靶材体；其中，靶材体包括：两个端段和中间段；其中，所述端段的第靶材厚度大于所述中间段的第二靶材厚度。该技术方案增加了靶材体的端段的厚度，延长
