source confidence: High status: Useful updated 2026-06-19
Summary
The official project website for the Telescope Array (TA), the largest ultra-high-energy cosmic-ray observatory in the Northern Hemisphere. Hosted by the collaboration with the University of Utah as lead institution.
Useful Claims
- The Telescope Array is located in Millard County, Utah, west of Delta.
- The collaboration is led by the University of Utah and the University of Tokyo ICRR.
- The detector array covers hundreds of square kilometers using surface scintillation detectors and air-fluorescence telescope stations.
- This capture describes TALE, the low-energy extension, and a separate expansion adding 500 scintillator detectors; it does not name that expansion TAx4.
- The site documents the collaboration's publications, news, and technical specifications.
Verbatim
"The Telescope Array project is a collaboration between universities and institutions in the United States, Japan, Korea, Russia, and Belgium." — Home page, welcome section
"The surface array samples events over 300 square miles of desert. It consists of more than 500 scintillator detectors, each 3 m 2 located on a 1.2 km (3/4 mile) square grid." — Home page, welcome section
"The Telescope Array has been collecting data in the high desert in Millard County, Utah, USA since 2007." — Home page, welcome section
"Led by the University of Utah (the U) and the University of Tokyo, the Telescope Array consists of 507 surface detector stations arranged in a square grid that covers 700 km 2 (~270 miles 2 ) outside of Delta, Utah in the state’s West Desert." — Home page, Amaterasu particle news item
"The Telescope Array is in the middle of an expansion that that they hope will help crack the case. Once completed, 500 new scintillator detectors will expand the Telescope Array will sample cosmic ray-induced particle showers across 2,900 km 2 (1,100 mi 2 ), an area nearly the size of Rhode Island." — Home page, "Expanding the footprint"
Reliability Notes
The capture discusses the TALE low-energy extension but does not confirm the page's TAx4-expansion claim.
The public project URL currently serves its content from dyndns-home.com; the captured page identifies itself as the Telescope Array collaboration site, but the infrastructure-level redirect is fragile and should be monitored.
Primary source from the collaboration itself. Technical claims and institutional affiliations are authoritative here. Specific measurement claims should be cross-checked against peer-reviewed publications (Physical Review Letters, Science) for independent validation.
