The hadronic component of the radiation received threatens the lifetime of these detectors and it is vital to choose the silicon starting material to maximise the performance and lifetime. Ion-implanted silicon detectors with various initial resistivities and germanium concentrations have been irradiated with high energy protons up to a fluence of 10/sup 14/ cm/sup -2/. The change in leakage current and full depletion voltage have been studied both as a function of fluence and of time after irradiation. Measurements were made up to 100 days post-irradiation at room temperature and then using heating techniques to accelerate processes up to the equivalent of over 10 years at room temperature. The leakage-current damage constant is shown to be independent of the starting material while the conduction type inversion point and the long-term annealing of the depletion voltage are sensitive to the initial resistivity and impurity concentrations.","PeriodicalId":310087,"journal":{"name":"Proceedings of the Third European Conference on Radiation and its Effects on Components and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130946701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the dose rate is increased, correlated failures are due to both cell photocurrent summation (rail span collapse) and supply voltage drop in peripheral circuits.

The light-reflecting fluorine-doped silica cladding is synthesized by the plasma outside deposition process. The aluminum coating technology used provides a very high strength of the fibers, unattainable for polymer coatings, and expands the fiber operating range up to 400/spl deg/C. It is established that the metal coating application can result in the annealing of the drawing-induced color centers with an absorption peak at 630 nm.

Reliability of data included in the base is achieved with: a standardization of total dose, neutron fluence and dose rate, test procedures; a standardization of test report presentation; a verification and a digital processing of experimental results before their transfer in the base. The pertinence of information obtained by this means enables an empirical and statistical analysis of the behaviour of the various component families, serving to define design rules of systems that have to resist a tactical nuclear aggression. This approach is illustrated with examples concerning the cumulative damage measured on 151 operational amplifiers in neutron fluence and on 70 MOS transistors in total dose, as well as the threshold effect existing in CMOS/bulk integrated circuits in dose rate on 226 components. Thanks to this analysis, the accumulation of test data should enable us to extract, by family, the characteristics representative of radiation effects, as well as their distribution law.","PeriodicalId":310087,"journal":{"name":"Proceedings of the Third European Conference on Radiation and its Effects on Components and Systems","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124164670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
