Abstract: THE DESIGN AND APPLICATION OF THE MULTIPOINT SOURCE FOR THE RADIATIVE LEVEL Liu Yuanxiang Hou Jianhua Wan Shushun (Dalian Institute of Applied Technology, CNNC,116032) ABSTRACT The methods of design, calculation and linear process of multipoint source are introduced. The multipoint source radiative level has been applied to some works. The accuracy of the radiative level are 2.5%. The multipoint source is made rather simply and cost cheaply than rodshapped source. So that, this kind of radiative level may be developed fast. Key words multipoint source radiative level rodshapped source linear process
