- ПубликацияТолько метаданныеComparative Assessment of Digital and UHF Optoelectronic Transceivers Radiation Hardness(2019) Mozhaev, R. K.; Cherniak, M. E.; Pechenkin, A. A.; Ulanova, A. V.; Nikiforov, A. Y.; Можаев, Роман Константинович; Печенкин, Александр Александрович; Уланова, Анастасия Владиславовна; Никифоров, Александр Юрьевич© 2019 IEEE.A method for radiation hardness evaluation of digital and microwave transmitting-receiving optoelectronic modules is presented. The technical aspects of parameters monitoring during exposure are described. The most vulnerable components of optoelectronic modules are identified.
- ПубликацияТолько метаданныеSoftware and Hardware System for Charge Coupled Devices with Interline Transfer of Charge Parameters Monitoring during Radiation Tests(2019) Lukashin, V. P.; Cherniak, M. E.; Akhmetov, A. O.; Nikiforov, A. Y.; Ulanova, A. V.; Лукашин, Владислав Павлович; Никифоров, Александр Юрьевич; Уланова, Анастасия Владиславовна© 2019 IEEE.The paper presents a method of device monitoring during radiation testing for charge coupled devices with interline transfer (hereinafter-CCD). The results of heavy ions, dose rate and total ionizing dose tests are presented together with the description of the developed software and hardware set-up based on the National Instruments platform and on the designed specialized equipment adapted for radiation tests.
- ПубликацияТолько метаданныеEvaluation of Organic Light-Emitting Diodes Total Ionizing Dose Sensitivity in Temperature Range(2021) Mozhaev, R. K.; Pechenkin, A. A.; Ukolov, D. S.; Ulanova, A. V.; Nikiforov, A. Y.; Можаев, Роман Константинович; Печенкин, Александр Александрович; Уланова, Анастасия Владиславовна; Никифоров, Александр Юрьевич© 2021 IEEE.The paper presents the comparative results of spectrum degradation organic light-emitting diode with different dominant wavelengths. The diodes were exposed with stationary gamma-irradiation at room and low temperatures. The research has shown moderate degradation of the light-emission spectrum when exposed at room temperature and significant degradation at low temperature. The greatest deterioration in the optical parameters was observed for organic light-emitting diodes with blue and white light emission color.
- ПубликацияТолько метаданныеMethod for Determining the Most Sensitive Region of an Optocoupler Chip under X-ray-Induced Dose Effects(2019) Ranneva, E. V.; Verizhnikov, A. I.; Tsyrlov, A. M.; Fedosov, V. S.; Chernyak, M. E.; Ulanova, A. V.; Nikiforov, A. Y.; Kalashnikov, V. D.; Titovets, D. O.; Уланова, Анастасия Владиславовна; Никифоров, Александр Юрьевич; Калашников, Владислав Дмитриевич; Титовец, Дмитрий Олегович© 2019, Pleiades Publishing, Ltd.Abstract: This paper is devoted to analyzing the effect of gamma radiation on the behavior of optocouplers. According to a series of experiments that involve masking various parts of a chip from X-ray irradiation, the most sensitive region of the chip is determined and the design of the optocoupler is improved. Upon modification, the radiation hardness of the device more than triples.
