Status report on project GRAND
J. Poirier, C. D'Andrea, E. Fidler +4
GRAND is an array of position sensitive proportional wire chambers (PWCs) located at 86.2 degrees W, 41.7 degrees N at an elevation of 220 m adjacent to the campus of the Universit…
A study of the Forbush decrease event of September 11, 2005 with GRAND
J. Poirier, M. Herrera, P. Hemphill +1
Project GRAND, a proportional wire chamber array, is used to examine the decreased counting rate of ground level muons during the Forbush decrease event of September 11, 2005. Data…
Forbush Decrease Data with a Simple Model
C. D'Andrea, J. Poirier, D. S. Balsara
On October 28, 2003 an earthward-directed coronal mass ejection (CME) was observed from SOHO/LASCO imagery in conjunction with an X17 solar flare. The CME, traveling at nearly 2000…
A Study of the Ground Level Event of April 15, 2001 with GRAND
C. D'Andrea, J. Poirier
Project GRAND, a proportional wire chamber array, is used to examine the increased counting rate of single muons during the solar Ground Level Event (GLE) of April 15, 2001. Data a…
Ground level muons in coincidence with the solar flare of April 15, 2001
J. Poirier, C. D'Andrea
The counting rate of single muon tracks from the Project GRAND proportional wire chamber array is examined during the Ground Level Event (GLE) of April 15, 2001. The GLE was seen b…
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…
