Abstract

A new scheme for bright hard x-ray emission from laser wakefield electron accelerator is reported, where pure nitrogen gas is adopted. Intense Betatron x-ray beams are generated from ionization injected K-shell electrons of nitrogen into the accelerating wave bucket. The x-ray radiation shows synchrotron-like spectrum with total photon yield 8$\times$10$^8$/shot and $10^8$ over 110keV. In particular, the betatron hard x-ray photon yield is 10 times higher compared to the case of helium gas under the same laser parameters. Particle-in-cell simulation suggests that the enhancement of the x-ray yield results from ionization injection, which enables the electrons to be quickly accelerated to the driving laser region for subsequent betatron resonance. Employing the present scheme,the single stage nitrogen gas target could be used to generate stable high brightness betatron hard x-ray beams.

Abstract

With improved neonatal care, the survival rate of premature infants has been greatly increased, and retinopathy of prematurity (ROP) has already been the leading cause of blindness in children. Thereupon screening and treatment of ROP have been deeply performed in China. However, the implementation and the detection rate vary greatly in different regions. In this article, based on the 20-year prevalence data of ROP in all parts of the country before 2010, we review and summarize the literatures from 2008 to 2018, in order to track and update the screening data of ROP in the mainland of China and to find the incidence trend during the decade. The evidence of the changing prevalence of ROP would benefit further prevention of this serious eye disease. (Chin J Ophthalmol, 2021, 57: 379-385) .
