Based on the molecular plating and brush plating technology,a new method for preparing large-area 241 Am source was developed.Compared with the traditional molecular plating,it broke through the restrictions of plating tank so that the active area of the source could be increased;and also,the automatic 2D travelling equipment resolved the problem of uniformity of large-area source through the controllable and well-regulated movement to and fro.Some sources were prepared to explore some experimental conditions such as time, voltage,and the acidity of solution that influenced the deposition efficiency of 241 Am.The uniformity and firmness of sources were also discussed.
