Telescope Array Project

The Telescope Array project is an international collaboration involving research and educational institutions in Japan, The United States, Russia, South Korea, and Belgium.

[1] The experiment is designed to observe air showers induced by ultra-high-energy cosmic ray using a combination of ground array and air-fluorescence techniques.

The hybrid setup of the Telescope Array project allows for simultaneous observation of both the longitudinal development and the lateral distribution of the air showers.

[5] By combining the data from the three sites, it is possible to determine the primary energy, the arrival direction, and the maximum point of longitudinal development for an air shower.

It features displays about the history of cosmic ray research in Utah and about the Telescope Array, which is spread across the desert west of Delta.

The center also includes a display about the nearby Topaz internment camp, where U.S. citizens of Japanese descent were imprisoned during World War II.

These stations measure charged particle densities (the shower footprint) at the Earth's surface for lower energy events approaching 3x1016eV The Telescope Array RADAR (TARA) Project is an effort to overcome some of the problems inherent to current cosmic ray detection techniques.

[12] In September 2012, the W. M. Keck Foundation awarded researchers at the University of Utah a $1 million grant to develop a bistatic radar detection system.

This system will be built alongside the existing Telescope Array and will use analog television transmitters and digital receivers to observe the range, direction and strength of cosmic rays in order to trace them back to their point of origin.
