The SLAC accelerator runs from the original injector, toward the top right, diagonally to the end stations, colliding beams, and offices this side of Hwy 280. When it was used for high energy physics, SLAC (originally Stanford Linear Accelerator Center) was used to discover new classes of particles, and led to several Nobel Prizes. Now it is poised for another groundbreaking career as a source of high-energy coherent X-rays: the LCLS (Linac Coherent Light Source). Jasper Ridge Biological Preserve, the bare ridge surrounded by forests halfway to Skyline, has also yielded important scientific results. JRBP stretches basically from the SLAC injector across to the left of this image. The bare ridge is its most prominent feature from this angle. Searsville Lake is hiding behind the ridge.
