High Performance SRF Cavities from Improved Superconductors and Production Techniques

由于其在科学和应用方面的许多成功，超导射频（SRF）已成为粒子物理，核物理和材料科学等基于加速器的科学的使能技术。然而，在充分实现这项技术的潜力方面仍然存在技术和科学挑战。 康奈尔大学的这一奖项将为SRF腔体的原位等离子体清洗研究提供支持，作为恢复和/或改善腔体介质场Q 0的有效方法，并系统地研究腔体的热循环如何提高其内在品质因数。该小组将使用温度测绘系统和现有的单细胞和9细胞腔进行这些研究。 该计划的更广泛影响是广泛的，包括跨加速器和材料科学的影响和研究生水平的学生研究。

Due to its many successes in science and applications, superconducting radio-frequency (SRF) has become an enabling technology for the accelerator-based sciences such as particle physics, nuclear physics and the materials sciences. Nevertheless, there remain technical and scientific challenges to the full realization of the potential of this technology. This award to Cornell will provide support for the study of in situ plasma cleaning of SRF cavities as an effective method to recover and/or improve the medium field Q0 of cavities and to systematically study how thermal cycling of a cavity increases its intrinsic quality factor. The group will use temperature mapping systems and existing single and 9-cell cavities for these studies. Broader impacts of the program are extensive, including impacts across accelerator and materials sciences and student research at the graduate level.
