Alpha energy resolution enhancement of a Si surface barrier detector

In this work, alpha energy resolution of a Si surface barrier detector was improved. For this purpose, we used constant fraction timing method. Energy resolution enhancement of about 1 % was achieved for alpha peak of 210Po. In order to prove the validity of the timing method, it was applied to the alpha spectrum of 226Ra. It was concluded that proposed method was successful on the energy resolution improvement. © 2012 Akadémiai Kiadó, Budapest, Hungary.99 BIL 001 197T087, 111T571 11 FEN 085Acknowledgments This work was supported by TUBITAK, the Scientific and Technical Research Council of TURKEY under Project Nos. 197T087 and 111T571, and by EBILTEM, Center of Science and Technology, Ege University under Project No. 99 BIL 001, and finally Scientific Research Foundation of Ege University under Project No. 11 FEN 085. -
