Abstract
This article presents a technique to restore X-ray bremsstrahlung spectrum.Through restoring the bremsstrah-lung spectrum of the imploded capsule,we can obtain the information of the pellet.Assuming the energy density in each energy band is equal,we divided the energy range into 5 parts,and with a specially-made multi-pinhole camera and an algebraic transfor-mation,we recorded images of the hot-spots.The images were produced on the imaging plate.In this way,five different linear e-quations were obtained and through this equation group,we could restore the spectrum.This approach was applied to hot-spot bremsstrahlung spectrum reconstruction of Shenguang Ⅲ prototype Facility.Based on the spectrum reconstruction,we deduced the temperature of the hot-spot,which is in line with the result obtained from the characteristic spectral line of the tracer element.关键词
