YBCO高温超导带材在大功率电力装备和强场磁体制备上具有非常重要的意义，但其性价比仍然是大规模应用的主要障碍。金属有机化学气相沉积（MOCVD）技术在规模化制备YBCO超导层方面具有明显的优势。本项目在现有的基带自加热技术基础上，通过流体动力学仿真模拟改善反应器结构，开展系统的实验研究，探索反应腔尺寸引起的气体流动变化、反应过程中的成分变化、薄膜沉积带来的温度变化等规律，找到解决薄膜高性能、沉积高速率、原料高利用率和带材高均匀性相矛盾问题的方法，以获得高性能低成本的双面高温超导带材的MOCVD制备技术。

YBCO high temperature superconductive (HTS) tapes have important applications in high power electrical devices and high-field magnet system because of its excellent electromagnetic characteristics. But the high price has limited its application. Based on Metal Organic Chemical Vapor Deposition (MOCVD), which is a potential large scale production technique for the deposition of superconducting thin film, we propose to calculate the gas flow velocity field, temperature distribution, particle diffusion rate, and the deposition rate distribution in different reaction chambers by computational fluid dynamics numerical simulation and obtain MOCVD process parameters influence. Combined with our electrical resistance direct heating technology, in which the current is inlet from the edge of tape with elastic electrode brush, we will develop compact reaction chambers with several millimeters in one dimension. In such a system, we will mainly investigate the experimental condition influence on thin film deposition rate, raw material utilization, superconductive, properties, and homogeneity. After that, further optimization will be accomplished and high performance low cost double-sided YBCO HTS tape samples will be prepared.
