Abstract
Many modern and future particle accelerators employ high gradient superconducting RF (SRF) to generate beams of high energy, high intensity and high brightness for research in high energy and nuclear physics, basic energy sciences, etc. In this paper we report the record performance large-scale SRF system with average beam accelerating gradient matching the International Linear Collider (ILC) specification of 31.5 MV m−1. Design of the eight cavity 1.3 GHz SRF cryomodule, its performance without the beam and results of the system commissioning with high intensity electron beam at Fermilab Accelerator Science and Technology (FAST) facility are presented. We also briefly discuss opportunities for further beam studies and tests at FAST including those on even higher gradient and more efficient SRF acceleration, as well as exploration of the system performance with full ILC-type beam specifications.

Many particle accelerators use superconducting radio frequency technologies to generate particle beams of high intensity, high brightness, and high energy. These particle beams are used for research and development in particle physics, nuclear physics, and also in industry.
Here in this paper, we report the record performance of the superconducting radio frequency accelerator. The problem is that it's been nearly a decade of work by permanent lab scientists and engineers and others worldwide. This superconducting RF power module is the first one to meet the international laser collider specifications
of an average accelerating gradient of 31.5 million electrons worldwide. Superconducting gradient are possible because of advances in the production of superconducting radio frequency
and the development of 50k feedback control systems. Here we have an international linear collider by Niobium cavity. We cooled using liquid helium to two kelvins. This cavity will resonate at 1.3 GHz with a quality factor of nearly 10 billion.
This makes the feedback and control system strictly important for accelerating electrons here at the Fermilab Accelerator Science and Technology School. We plan to use this heat superconducting radio frequency linear accelerator to support broad spectrum experiments.
We anticipate finding physical results in our facility. Thank you for your attention.
