NSLS-II is a synchrotron light source, designed to produce X-rays 10,000 times brighter than BNL's original light source, the National Synchrotron Light Source (NSLS). NSLS-II supports research in energy security, advanced materials synthesis and manufacturing, environment, and human health. [4]
The National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory (BNL) in Upton, New York was a national user research facility funded by the U.S. Department of Energy (DOE). Built from 1978 through 1984, and officially shut down on September 30, 2014, [2] the NSLS was considered a second-generation synchrotron. [3]
A synchrotron light source is a source of electromagnetic radiation (EM) usually produced by a storage ring, [1] for scientific and technical purposes. First observed in synchrotrons , synchrotron light is now produced by storage rings and other specialized particle accelerators , typically accelerating electrons .
The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour).
Inside the storage ring at the Advanced Light Source, Lawrence Berkeley National Laboratory. Large magnets bend, steer, and focus the electron beam as it circles the ring 1.4 million times per second. Electron bunches traveling near the speed of light are forced into a nearly circular path by magnets in the ALS storage ring.

"Planets look more like a steady light, while stars often twinkle because their light is affected by Earth’s atmosphere," Conafoy says. Planets also might take on "distinctive colors," Conafoy says.
The two-way speed of light is the average speed of light from one point, such as a source, to a mirror and back again. Because the light starts and finishes in the same place, only one clock is needed to measure the total time; thus, this speed can be experimentally determined independently of any clock synchronization scheme.
