Design And Construction

National Synchrotron Light Source (NSLS-II) is a new 3 GeV, 500 mA, high-brightness synchrotron light source facility being built at the Brookhaven National Laboratory. Approved for construction in January 2009, the NSLS-II project is expected to be completed in June 2014. In this paper we discuss the present status of the mechanical design and construction of some major components of this facility, namely (i) conventional facilities, (ii) injector complex (iii) storage ring, (iv) RF system and (v) beamlines.

Beam Position Monitors

The National Synchrotron Light Source II currently under construction at the Brookhaven National Laboratory is expected to provide unprecedented orbit stability in the storage ring in order to fully utilize the very small emittance of the electron beam. The desire to measure the position of such small beams to high resolution imposes stringent requirements on the thermal and structural stability of the supports for the beam postion monitor (BPM) pick-up electrodes located on multi-pole vacuum chambers and more so on those located upstream and downstream of insertion device sources where the beam size is the smallest. Even with tunnel air temperature expected to be controlled to ±0.1°C, low coefficient of thermal expansion materials is required to meet this level of thermal stability. Here, we present the application of these materials to the design of stable supports for radio frequency (RF)-BPMs as well as the methods of testing their performance.

National Synchrotron Light Source II (NSLS-II), a new state-of-the-art third-generation light source under construction at Brookhaven National Laboratory is expected to have extremely small emittance and extraordinary beam stability. The mechanical requirements for beam diagnostics and instrumentation are exceptionally challenging. Here we present an overview of the mechanical aspects of some NSLS-II diagnostics as well as the performance levels of some systems currently under development.

National Synchrotron Light Source II (NSLS-II) will be a 3-GeV, 792-m circumference third-generation synchrotron radiation facility with ultralow emittance and extremely high brightness. Front ends are required to transmit synchrotron radiation from the storage ring to the beam line while providing equipment and personnel protection. There will be up to 57 front ends in the NSLS-II facility with six in the baseline. Original designs are being developed and will be manufactured for three non-canted in-vacuum undulators, one canted in-vacuum undulator, one elliptically polarized undulator and one damping wiggler. Bending magnet and three-pole wiggler front ends are also being designed. Power densities range from 0.3 to 89.8 kW mrad−2, with total powers ranging from 0.34 to 64.5 kW. All components intercepting synchrotron radiation are water cooled and were analysed to confirm acceptable thermal limits.

Data Analysis Methods

Soft X-ray microscopy allows one to study nanoscale heterogeneities in dry and wet environmental science, biological, polymer, and geochemical specimens. Recent advances in instrumentation at the X-1A beamline at the National Synchrotron Light Source at Brookhaven National Laboratory are described. Spectromicroscopy data analysis methods including component mapping and principal component analysis (PCA) are then discussed.
