High Performance SRF Cavities from Improved Superconductors and Production Techniques

超导射频(SRF)由于其在科学和应用上的许多成功，已经成为粒子物理、核物理和材料科学等以加速器为基础的科学的使能技术。然而，要充分实现这项技术的潜力，仍然存在技术和科学方面的挑战。这项授予康奈尔大学的奖项将为SRF腔的原位等离子体清洗研究提供支持，将其作为恢复和/或改善腔的介质场Q0的有效方法，并系统地研究腔的热循环如何提高其固有品质因数。该小组将使用温度测绘系统以及现有的单细胞和9细胞腔体进行这些研究。该项目的广泛影响是广泛的，包括对加速器和材料科学的影响，以及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.
