Thermal Annealing of Chemical Radiation Damage

Laser annealing heals radiation damage in avalanche photodiodes

Avalanche photodiodes (APDs) are a practical option for space-based quantum communications requiring single-photon detection. However, radiation damage to APDs significantly increases their dark count rates and thus reduces their useful lifetimes in orbit. We show that high-power laser annealing of irradiated APDs of three different models (Excelitas C30902SH, Excelitas SLiK, and Laser Componen...

Non-Thermal Electromagnetic Radiation Damage to Lens Epithelium

High frequency microwave electromagnetic radiation from mobile phones and other modern devices has the potential to damage eye tissues, but its effect on the lens epithelium is unknown at present. The objective of this study was to investigate the non-thermal effects of high frequency microwave electromagnetic radiation (1.1GHz, 2.22 mW) on the eye lens epithelium in situ. Bovine lenses were in...

Radiation Damage and Annealing in 1310nm InGaAsP/InP Lasers for the CMS Tracker

Radiation damage in 1310nm InGaAsP/InP multi-quantum-well lasers caused by 0.8MeV neutrons is compared with the damage from other radiation sources, in terms of the increase in laser threshold current. The annealing behavior is then presented both in terms of both temperature and forward-bias current dependence. The annealing can be described by a model where radiation induced defects have a un...

MHD thermal radiation and chemical reaction effects with peristaltic transport of the eyring-powell fluid through a porous medium

In this paper, we analyze the thermal radiation and chemical reaction impacts on MHD peristaltic motion of the Eyring-Powell fluid through a porous medium in a channel with compliant walls under slip conditions for velocity, temperature, and concentration. Assumptions of a long wave length and low Reynolds number are considered. The modeled equations are computed by using the perturbation metho...
