BDN NSLS-II Project Status: How to Recycle a Synchrotron?

With many synchrotron facilities retiring or going through upgrades, what is the future of some of the stateof-the-art equipment and the beamlines built for a specific science at these older facilities? Can the past investments continue supporting the current scientific mission? The Beamlines Developed by NSLS-II (BDN), former NxtGen project, are reusing scientifically valuable equipment recovered from the now shuttered NSLS. For example TES(8-BM) reported 2um x 3um beam size achieved with reclaimed KB mirrors [1]. This paper describes new, reused, adapted and modified instruments, which NSLS beamlines they came from, as well as their integration into the new NSLS-II control system. Many popular NSLS programs and custom-built equipment developed for them are welcoming old and new users in NSLS-II. INRODUCTION Every facility puts efforts into minimize maintenance by standardizing common infrastructure and utilities. All BDN beamlines received the following new standardized equipment: photon shutters, vacuum gauges and controllers, Beam Intensity (BI) Monitoring equipment, CCDs and surveillance cameras, network and computing infrastructure, Personnel Protection System (PPS) and Equipment Protection System (EPS). Most of the beamlines received new optic for the mirrors, while reusing vacuum chambers and motorized positioning systems. Some mirrors were reused, as well as end station equipment. Fig. 1 shows X15B instruments being moved to NSLS2. BDN is home for instruments developed by scientific non-commercial groups. CMS(11-BM), TES(8-BM), and XFM (4-BM) use KB-mirrors, designed by the Center for Advanced Radiation Sources (CARS) at the University of Chicago [1]. In-house developed electrometer by P. Siddons was used in many beam diagnostic solutions at all BDN beamlines. This design is now sold commercially [2]. All beamlines reused ion pumps and ion pump controllers, gate valves, bellows, viewports and more, wherever it was suitable, with some beamlines building mostly from recovered components. * This research used resources of the National Synchrotron Light Source II, a U.S. Department of Energy (DOE) Office of Science User Facility operated for the DOE Office of Science by Brookhaven National Laboratory under Contract No. DE-SC0012704." 16th Int.
