2014 WSU Abstract: Flux Study

How Muon Flux is Affected by Barometric Pressure and Temperature

Andie Anger and Oscar Mota
The purpose of this study was to conclude whether temperature and pressure have an effect on the fluctuation of muon flux. In order to test this, four muon detectors were set in a stacked formation and recorded data from Monday night at 5 p.m. to Friday morning at 9 a.m. The coincidence was set at two-fold. Upon analysis of the data, a graph for each channel was created with a 600 second bin width, and the data points were exported to an Excel Spreadsheet. The extreme flux counts were noted, and were then tested with a two sample t-test to determine significance. These were then compared with barometric pressure and temperature data that was tested by a two sample t-test. Since the fluctuations in muon count and pressure/temperature corresponded, it was concluded that temperature was a significant factor in muon flux count.
