About John Linsley
- John David Linsley (12 March 1925 – 25 September 2002) was an American physicist who performed pioneering research on cosmic rays, particularly ultra-high-energy cosmic rays.
- He did his most significant work from 1959 to 1978 using a ground-based array of detectors at Volcano Ranch in New Mexico.
- He is best known for being the first to detect an air shower created by a primary particle with an energy of 1020 eV.
- This was the highest energy cosmic ray observed up to that point.
- Linsley's observations suggested that not all cosmic rays are confined within the galaxy and showed the first evidence of a flattening of the cosmic ray spectrum at energies above 1018 eV.
