Status Report of Project GRAND: An Extensive Air Shower Array of Proportional Wire Chambers

Authors

Description

Project GRAND is an extensive air shower array utilizing position sensitive detectors of proportional wire chambers. The 64 detectors deployed in a field 100 m x 100 m are located at 86.2 deg W and 41.7 deg N, at 220 m above sea level. The project was completed about two years ago and has been taking data, simultaneously on two triggers: 1) multiple-hit coincidence triggers which collect data on extensive air showers, and 2) 200 Hz triggers which collect the single tracks stored in each station during the last 5 msec.
