Narrow Cosmic-Ray Showers
It has been found that the cosmic-ray particles which occur in showers of small angular divergence are much more penetrating than those of the usual type of shower. The particles in such "hard showers" are clearly not electrons and are interpreted as medium and low energy mesotrons. The second maximum of the Rossi curve, which is accentuated for small-angle shower arrangements, can be accounted...
متن کاملChanges of the cosmic-ray mass composition in the 1014–1016 eV energy range
Data taken with ten Cosmic Ray Tracking (CRT) detectors and the HEGRA air-shower array on La Palma, Canary Islands, have been analysed to investigate changes of the cosmic-ray mass composition at the ‘knee’ of the cosmic-ray flux spectrum near 1015 eV energy. The analysis is based on the angular distributions of particles in air showers. HEGRA data provided the shower size, direction, and core ...
متن کاملRadio Pulses from Cosmic Ray Air Showers
The first experiment in which radio emission was detected from high energy particles is described. An array of dipoles was operated by a team of British and Irish physicists in 1964-5 at the Jodrell Bank Radio Observatory in conjunction with a simple air shower trigger. The array operated at 44 MHz with 2.75 MHz bandwidth. Out of 4,500 triggers a clear bandwidth-limited radio pulse was seen in ...
متن کاملAngular deviation of secondary charge particles in 1014-1016 eV extensive air showers: Constrains on application of hodoscopes
Deviation angles of secondary electrons and muons in simulated extensive air showers were studied. The angles have wide distribution, whose width depends on energy cuts imposed on shower particles. In this work, variation of deviation angles with the energy of secondary particles, shower energy, primary direction, and core distance was investigated. The results put limitations on application ...
متن کاملLOPES Detecting Radio Emission from Cosmic Ray Air Showers
Radio pulses emitted in the atmosphere during the air shower development of high-energy primary cosmic rays were measured during the late 1960ies in the frequency range from 2 MHz to 520 MHz. Mainly due to difficulties with radio interference these measurements ceased in the late 1970ies. LOFAR (Low Frequency Array) is a new digital radio interferometer under development. Using high bandwidth A...
