Abstract
"A high-performance technology platform to prepare coated conductors based on high-temperature superconductors (HTS) currently exists. Large scale commercialization of this technology is delayed due to the non-availability of a viable,cost effective HTSprocessing method that could provide a sufficiently high quality material. The current SBIR proposes a solution to this problem.We propose a new, cost effective and energy efficient processing method for the preparation of high temperature superconducting (HTS) coated conductors. The proposed pulsed electron-beam technology, in addition to having the same intrinsic potentialas the pulsed laser deposition ( a technique that has delivered the best quality HTS films), can be orders of magnitude more efficient, economical and scalable. Manufacturing equipment for HTS coated conductors based on pulsed electron-beam technology willbe commercialized by Neocera.In our Phase I effort, we plan to improve the stability and reliability of pulsed electron-beam source for producing HTS coated conductors. The improved source will be tested by evaluating HTS film quality obtained on biaxially textured substratesproduced by RABiTS (rolling-assisted biaxially textured substrates) and IBAD (ion beam assisted deposition) approaches.Phase II will focus on scaling up this technology where pulsed electron beam arrays will be developed, optimized and integrated with areel-to-reel deposition system f
