Soft X-Ray Photoemission Properties for the Newly Modeled Materials Gold, Silver, Copper, and Carbon

摘要

The work represents a continuation in our program to model soft x-ray photoemission for exploding wire radiator (EWR) sources incident on various materials. This program falls within the larger program SKYNET which is concerned with SGEMP effects for soft x-ray sources. Results are presented for four newly modeled materials - Au, Ag, Cu, and C. These results include the detailed atomic information required to model each material and photoemission and backscatter results obtained with the code SXRP. In particular, photoemission spectra and total primary yields are presented for an EWR source incident on the four materials cited. Their measured counterparts are included for comparison. Some comparisons provide good agreement while others call for further investigation. For Au, additional spectra and yields are presented for sources narrow in energy to compare with available published data. The photon energy range considered is between 1 and 5 keV. Good overall agreement is obtained with the data. (Author)
