Polymer waveguide (WG) S-bends are necessary for fan-out routing techniques and optical splitting in high-density optical interconnects. Designing and manufacturing of optimal S-bends are critical for minimizing optical link loss while maintaining overall size and layout constraints. Complete structural loss analysis is demonstrated theoretically and shown experimentally utilizing both radial a...

The Canadian Light Source (CLS) storage ring has been operating routinely since commissioning was completed in the spring of 2004. Beam currents up to 230 mA have been achieved with the single superconducting RF cavity. With steady improvement beam lifetimes (1/e) of 14 hours at 200 mA and 0.5% coupling are now possible. In the last year the vertical tune was increased by 1 integer to produce a...

The aim of this study was to determine the influence running wide on bends regarding intermediate changes position, dispersion athletes, and speed relative season best (SB) between medalists non-medalists in men’s women’s 800 m championship finals. Extra distance covered measured using official videos. total run calculated described as minimum calculable distance. Theoretical mean speeds, theor...

The BESSY VSR upgrade of the BESSY II light source [1] represents a novel approach to simultaneously store long (ca. 15ps) and short (ca. 1.5ps) bunches in the storage ring with the “standard” user optics. To this end, new high-voltage L-Band superconducting multi-cell cavities must be installed in one of the straights of the ring. These 1.5 GHz and 1.75 GHz cavities are based on 1.3 GHz system...

The 3rd generation of light sources have exceptionally low emittances (1-5 nm-rads) at energies of a few GeV. Generic design procedures for their storage ring lattices are now available and will be reviewed in the talk. These procedures involve both linear matching of arc sections (eg achromats) to straights of variable length, based on both accelerator and user needs, and nonlinear dynamics co...

We review the work carried out in the X13 R&D Straight Section of the NSLS X-Ray Ring on small gap in-vacuum undulators (IVUNs). Then we discuss: (1) plans to replace the pure permanent magnet undulator in X13 by a hybrid design providing stronger magnetic fields, enhancing the tunability of the device; (2) plans to install hybrid IVUNs in the two RF straights of the X-Ray Ring, increasing the ...

The SPEAR 3 Upgrade Project seeks to replace the present 160 nm-rad FODO lattice with an 18 nm-rad double bend achromat (DBA) lattice. The new lattice must conform to the layout of the SPEAR racetrack tunnel and service the existing photon beamlines. Working within these constraints, we designed a lattice with 18 achromatic cells and 3 GeV beam energy. This paper reports on design of the main D...
