To study and reveal the radiation damage of the silicon drift detector (SDD) in a deep-space environment, which will degrade the detector performance, in this paper, the SDD radiation damage effects and mechanics, including displacement damage and ionization damage, for irradiations of different energy of neutrons and gammas are investigated using Geant4 simulation. The results indicate the recoil atoms distribution generated by neutrons in SDD is uniform, and recoil atoms\u2019 energy is mainly in the low energy region. For secondary particles produced by neutron irradiation, a large energy loss in inelastic scattering and fission reactions occur, and neutron has a significant nuclear reaction. The energy deposition caused by gammas irradiation is linear with the thickness of SDD; the secondary electron energy distribution produced by gamma irradiation is from several eV to incident particle energy. As the scattering angle of secondary electron increases, the number of secondary electrons decreases. Therefore, a reasonable detector epitaxial thickness should be set in the anti-irradiation design of SDD.<\/jats:p>","DOI":"10.3390\/s19081767","type":"journal-article","created":{"date-parts":[[2019,4,15]],"date-time":"2019-04-15T11:15:58Z","timestamp":1555326958000},"page":"1767","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Simulation of Radiation Damage for Silicon Drift Detector"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9725-6007","authenticated-orcid":false,"given":"Yang","family":"Liu","sequence":"first","affiliation":[{"name":"School of Nuclear Science and Engineering, North China Electric Power University, Beijing 102206, China"},{"name":"State Key Laboratory of Intense Pulsed Radiation Simulation and Effect, Xi\u2019an 710024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tengfei","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Nuclear Science and Engineering, North China Electric Power University, Beijing 102206, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianxi","family":"Yao","sequence":"additional","affiliation":[{"name":"Renewable Energy School, North China Electric Power University, Beijing 102206, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoping","family":"Ouyang","sequence":"additional","affiliation":[{"name":"School of Nuclear Science and Engineering, North China Electric Power University, Beijing 102206, China"},{"name":"State Key Laboratory of Intense Pulsed Radiation Simulation and Effect, Xi\u2019an 710024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,13]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"ARPA\/DARPA space programs","volume":"8","author":"Pines","year":"2004","journal-title":"XNAV Ind.
