Yi Xie
I'm a graduate student working with Prof. Matthias Liepe and Prof. Hasan Padamsee on Superconducting Radio Frequency (SRF) cavities at Laboratory for Elementary-Particle Physics of Cornell University.
SRF cavities made of niobium (Nb) are the essential parts of future particle accelerators such as the International Linear Collider (ILC) and Energy Recovery Linac (ERL) due to the fact that they can be operated at high gradient, high current and continuous wave conditions.
My research focuses on developing a sample test system to measure high field RF properties of higher temperature superconductors like Nb3Sn and MgB2. In addition, my work includes surface analysis of material samples to find correlations between the RF performance of superconductors and their surface properties like roughness and crystal dislocations.
Biographical sketch
I grew up near the legendary Wudang Mountain which is one of the birth places of Chinese martial arts. After obtaining a telecommunication engineering degree at CQUPT, I went to the School of Physics at Peking University to fulfill my dream of studying physics. I entered a fascinating field of accelerator and beam physics while working with Profs. Chen Jiaer, Fang Jiaxun, Guo Zhiyu and Liu Kexin on Radio Frequency Quadrupole (RFQ) accelerator. After graduating from Peking University with a master's degree, I've been working at Cornell SRF group to get my PhD degree in physics.
