A Measurement of Secondary Muon Angular Distributions
J. Poirier, C. D'Andrea
Project GRAND is an array of proportional wire chambers composed of 64 stations with each station containing eight proportional wire planes and a 50 mm steel plate. The proportiona…
Status of Project GRAND's Proportional Wire Chamber Array
J. Poirier, D. Baker, J. Barchie +9
Project GRAND is an extensive air shower array of proportional wire chambers. It has 64 stations in a 100m x 100m area; each station has eight planes of proportional wire chambers…
A Project GRAND Study of the GLE of July 14, 2000
J. Poirier, C. D'Andrea, M. Dunford
The Ground-Level Event (GLE) associated with the X5.7 solar flare of July 14, 2000 is studied by the Project GRAND proportional wire chamber array. Results are compared to those ob…
Variation of Muon Counts Versus Solar Time
J. Poirier, C. D'Andrea
Project GRAND observes small variations in the number of incident muons when plotted versus local solar time. The total accumulated number of muons by GRAND over four years' time i…
Secondary Muon Asymmetries at Sea Levell with Low Systematics
J. Poirier, C. D'Andrea, M. Dunford
Project GRAND has the capability of measuring the angle and identity of single tracks of secondary muons at ground level. The array is comprised of 64 stations each containing eigh…
