[en] When we use accelerator beam for researches, we must apply different detection methods for different radiation environments which were given by accelerator beam conditions. The case of KOMAC proton accelerator, it generate a pulse type proton beam, and the maximum current of each pulse beam could be as high as 20 mA. This high current pulse beam makes saturations of detector signals. Moreover, it is necessary to develop a Multi Functional detector for various conditions of radiation environment. In addition, we need to develop proper electronic circuits for new type of detector development and software for data taking and analysis of the data
