An Accessible platform for simultaneous Macro, Meso and Microscopic Measurements of Polymeric Materi
Abstract
This proposal requests support for a three year period project to carry out fundamental research directly tied to the advancement of, effective high lethality HPM sources. It involves developing anode materials that reduce the number of adsorbates on the surface wh,ich can limit both the repetition rate of HPM sources and the pulse length. It is not known a priori if long pulse or high repetitio,n sources will have a greater effect on the target - this needs to be tested. What is known is that electromagnetic energy is requir,ed to affect a target, and designing electrodes with lower adsorbate load will increase the energy and hence, very likely, the letha,lity of HPM sources. This work is multipronged and has at its heart a novel idea, for which we will apply for a patent on reducing t,he adsorbate load content. In one part of this collaborative research project, the nature, ionization level of these neutrals will b,e determined by careful experimental measurements of the adsorbate load on cathode and anode materials on UNMs LTD test bed by utili,zing time and spatially resolved diagnostics. A second parallel part will involve Molecular Dynamics (MD), Monte Carlo and first pri,nciple atomic physics Density Functional Theory (DFT) simulations on the likely hydrogen content on these materials and how these wi,ll be reduced via shock loading of the first few monolayers of the material. This parallel paired collaborative proposal is between,Dr. Salvador Portillo at the University of New Mexico (UNM) and Dr. Ravi Joshi at Texas Tech University (TTU). UNM will lead the exp,erimental effort, and TTU will lead the material numerical simulations for quantitative predictions, experimental validation and opt,imization. This is approved for Public Release.
