用于测量Z箍缩铝等离子体K层辐射的邻苯二甲酸氢铊弯晶摄谱仪
TAP curved crystal spectrometer for diagnosing K-shell radiation of aluminum Z-pinch plasma
摘要
Abstract
A temporally- and spatially-resolved X-ray spectrometer,with spectral range of 1 500~2 300 eV and temporal resolution about 2 ns,has been developed for diagnosing K-shell radiation of aluminum wire array Z-pinch plasma driven by Qiangguang-I generator (1.5 MA,80~100 ns).It consisted of an elliptically-curved TAP crystal and a four-channel X-ray frame camera.Theoretical analyses were made to check out possible effects of different signal transfer and conversion processes on spectral response of the spectrometer.It recorded time-resolved and -integrated K-shell resonance lines of H-,He-like aluminum ions and satellite lines of Li-,He-like ions.Results were compared with spectral-resolved X-ray images obtained by pinhole cameras.Time-resolved K-shell spectra show many differences on line ratios and axial distribution with each other and time-integrated results,which exhibits variations of electron temperature and ion population on a 5~10 ns time scale.关键词
