The Brookhaven Accelerator Test Facility (ATF) pioneered the principles of Accelerator Stewardship and served the Advanced Accelerator Concepts community as a users’ facility for over two decades. Over this time, the ATF provided facilities and expert support free of charge for users from academia, industry and national labs with a unique combination of high-brightness electron beams and high power lasers synchronized with the electron beam as well as diverse beam instrumentation and control software. There are over 30 scientists who did all or part of their graduate degree work using the ATF. The Accelerator Stewardship is now a formal program at the Office of High Energy Physics (OHEP), and the ATF has been awarded a transformational upgrade by OHEP, the ATF-II, that will lead in a short time to a dramatic increase in the capabilities of the facility. The Stewardship mission and the ATF-II will be the subject of this presentation.

RadiaBeam Systems successfully completed testing of a proof-of-concept corrugated plate dechirper at the Brookhaven National Laboratory Accelerator Test Facility.* Such passive devices should prove indispensable for the efficient operation of future XFEL facilities. These experiments demonstrated a narrowing of the energy spectrum in chirped beam bunches at 57.6 MeV. In this paper, we compare these results with results from Elegant simulations of the BNL-ATF beam. We also compare GdfidL simulations of the wakefield with the analytic results of Bane and Stupakov.**
