The infrared-induced temperature distributions of solid D2 ices

A specific-wavelength infrared（IR） light（λ = 3140 nm） was irradiated into a solid D2 ice prepared in a cylinder target cell.The temperature in the solid D2 ice oscillated periodically with a high amplitude when irradiated by the IR light.The temperature oscillation has been well explained based on t...

More Information
Summary:A specific-wavelength infrared（IR） light（λ = 3140 nm） was irradiated into a solid D2 ice prepared in a cylinder target cell.The temperature in the solid D2 ice oscillated periodically with a high amplitude when irradiated by the IR light.The temperature oscillation has been well explained based on the two-dimensional heat transfer theory plus the IR-irradiation effect.The transmission optical imaging reveals that such a temperature oscillation is favorable to recrystallize the solid D2 ice from multicrystal to quasi single crystal.This suggests an efficient method to layer the solid hydrogen-isotope ice for the inertial-confinement-fusion（ICF） experiments.
