Abstract
Abstract A detector suitable for use in the study of cosmic-ray showers above 1019 eV has been operated at a remote location, within the Haverah Park air shower array, under the control of a computer located at the centre of the array. A microprocessor handled pulse height and timing data at the detector and also responded to command signals transmitted via a 2-way radio link from the computer by initiating the transmission of detector data back to the computer. The computer then found those measurements which corresponded to air showers by looking for matching times between the remote detector and the central detector of the array. The timing measurements were derived from broadcast television signals and were accurate enough to allow the incident directions of air showers to be calculated with an error of less than ±3.5°.
