Thomas Jefferson National Accelerator Facility (TJNAF), commonly called Jefferson Lab or JLab, is a US Department of Energy National Laboratory located in Newport News, Virginia. [ 1 ] Since June 1, 2006, it has been operated by Jefferson Science Associates, LLC, a limited liability company created by Southeastern Universities Research ...
SLAC National Accelerator Laboratory, originally named the Stanford Linear Accelerator Center, [2] [3] is a federally funded research and development center in Menlo Park, California, United States. Founded in 1962, the laboratory is now sponsored by the United States Department of Energy and administrated by Stanford University .
The SLAC 2-mile linear accelerator was the original source for 3GeV electrons, but by 1991 SPEAR had its own 3-section linac and energy-ramping booster ring. Today, the SPEAR storage ring is dedicated completely to the Stanford Synchrotron Radiation Lightsource as part of the SLAC National Accelerator Laboratory facility.
The local irradiance near the area is about 7.4 kWh/m 2 /day [53] [54] (annual average) for a total solar energy flow in the visible spectrum of 2.717 MWh/m 2 yearly. One heliostat mirror is a 75.6 square feet (7.02 m 2 ) reflecting surface, [ 55 ] giving a total of 151.2 square feet (14.05 m 2 ) per heliostat.
The project includes 10,347 heliostats that collect and focus the sun's thermal energy to heat molten salt flowing through an approximately 656-foot (200 m) tall [13] solar power tower. Each heliostat is made up of 35 6×6 feet (1.8 m) mirror facets, yielding a heliostat overall usable area of 1,245 square feet (115.7 m 2 ).

The journal focuses on accelerator physics and engineering. [1] Its lead editor is Frank Zimmermann . The journal was established in 1998 as Physical Review Special Topics – Accelerators and Beams, obtaining its current title in 2016. [2]
After three years of construction and testing, the new accelerator facility became operational in December 1968. [7] Henry Newson, a nuclear physics professor at Duke University, was responsible for the proposal, was the original proponent of combining the efforts of the three universities, and served as the first director of the new laboratory ...
