Radio signals from extensive air showers with the energies E 0 ≥ 1019 eV according to data from the Yakutsk extensive air shower array

A large aperture, five element cosmic ray telescope was operated in conjunction with an air shower array in a search for long lived particles, delayed between 1 and 45 μs after extensive air showers. After sampling ~ 29 000 air showers with an energy greater than ~ 1014 eV, over a period of 9 months, an excess of 11 such events were observed with time delays in the interval of 1 to 6 μs following the showers. The events in the remainder of the 45 μs interval were consistent with background random coincidences. We estimate that only 1 of the 11 excess events might be attributable to afterpulsing in our telescope photomultiplier tubes. All the excess 'trailing particle' events can be explained as being due to electrons resulting from shower associated muons that stop and decay in the vicinity of the cosmic ray telescope.

Air Shower Array

A search has been made for very high energy photons from the direction of the Crab Pulsar using the Lodz extensive air shower array. This device is particularly suitable for such a study because it consists of a large muon detector which can be used to search for the characteristic muon poor showers.

The Chacaltaya air shower array has continued to be used for the accumulation of muon-poor air showers in an attempt to find evidence of gamma rays in the primary cosmic radiation. A progress report is given here, and some upper limits to the intensities are presented for possible point sources and for galactic and isotropic backgrounds.
