Radiation tolerance of perovskite solar cells under gamma ray

Organic electronics, 2019
Perovskite solar cells (PSCs) have been developed rapidly in recent years, representing the most promising candidates for photovoltaics. Regarding their application in spacecraft, it is essential to exploring the space radiation tolerance of PSCs.

Spinal cord radiation tolerance

International Journal of Radiation Oncology*Biology*Physics, 1994
Each case of radiation myelopathy represents a unique occurrence where an individual’s tolerance was exceeded. Therefore, each case offers the challenge to determine why this patient’s tolerance was exceeded at a dose that other patients tolerate.

Carbon Nanotubes for Radiation-Tolerant Electronics

ACS Nano, 2021
Electronics for space applications have stringent requirements on both performance and radiation tolerance. The constant exposure to cosmic radiation damages and eventually destroys electronics, limiting the lifespan of all space-bound missions. Thus, as space missions grow increasingly ambitious in distance away from Earth, and therefore time in space,

Investigating the effect of material microstructure and irradiation temperature on the radiation tolerance of yttria stabilized zirconia against high energy heavy ions

Journal of Applied Physics, 2019
Yttria stabilized zirconia pellets with different crystallite sizes were irradiated with 80 MeV Ag6+ ions at room temperature and 1000 K to understand the effect of crystallite size/material microstructure and irradiation temperature on the radiation ...

A Radiation Tolerant Photodetector

IEEE Transactions on Nuclear Science, 1987
This paper describes the development and test of a radiation tolerant photodetector. This was accomplished by building a single stage photo multiplier tube with a physically small, dielectrically isolated, silicon photodiode array at the anode. In this device the optically generated photocurrent is multiplied by a much larger factor than is the photo ...

Key factors in radiation tolerance of BCC metals under steady state

Nuclear Instruments and Methods in Physics Reseach B, 2019
Different materials would exhibit discrepant behaviors of radiation tolerance under energetic particle irradiation, due to the effect of intrinsic features (like defect migration energy and sink strength of grain boundaries) and extrinsic conditions ...

Radiation Tolerant Magnetic Amplifier

IEEE Transactions on Nuclear Science, 1963
Several operational magnetic amplifier stages of low and medium power levels were designed and tested in a nuclear radiation environment to levels of 1 x 1016 neutrons/cm2 (E > 0.1 Mev) and were found to exhibit acceptable performance. Various diode characteristics were obtained under radiation to correlate behavior with amplifier designs.

Radiation-tolerant supervisory circuits

Conference on Electron Devices, 2005 Spanish, 2005
This paper is devoted to the description of the evolution of different commercial microprocessor supervisory circuits under neutron radiation. After the irradiation, the tested devices showed some interesting changes: the increase of supply current and the duty cycles for watchdog timer.

Radiation tolerant SMART electronics

Conference Record of the 1991 IEEE Nuclear Science Symposium and Medical Imaging Conference, 2002
Summary form only given, as follows. SMART transmitters contain a microprocessor and other digital electronic circuits that are used to enhance accuracy, provide communications, reduce maintenance, and otherwise facilitate use. SMART transmitters are used extensively in factories, refineries, and elsewhere, but they are not used in nuclear power plants,

Radiation-Induced Tolerance

1977
Radiation-induced tolerance in the immunological response is fundamentally a result of cell death and necrosis of lymphatic and hematopoietic tissues. The energy of ionizing radiation is absorbed in a physical sense in tissue, primarily by ionizing water, yielding extremely reactive chemical products of water, which in turn alter macromolecules in ...
