This paper presents the special character of a new type of plastics sc intillator prepared for the diagnosis of the total xrays in Zpinch. The expe ri mental results in the laboratory of Beijing Synchrotron Radiation Facility (BSRF ) indicate that the scintillator has a characteristic of even energy respond in the energy region from 100eV to 1400eV, heavy restrain of visible light, fast de cay time of 6ns.
