Washington Large Area Time Coincidence Array (original) (raw)

The Washington Area Large-scale Time-coincidence Array (WALTA) is a cosmic ray physics experiment run by the University of Washington to investigate ultra high energy cosmic rays (>1019eV). The program uses detectors placed at Seattle-area high schools and colleges which are linked via the internet, effectively forming an Extensive Air Shower array. In addition to working on the unexplained levels of Ultra High Energy cosmic ray (UHECR) flux, it hopes to serve as a pedagogical tool for increasing the physics involvement of high schools and community colleges with a University level physics experiment. Each site has three to four scintillation detectors with the goal of having enough sites to cover a 200 km2 area around the city of Seattle. WALTA is a part of the larger NALTA project which
