### Study of life time of muons

1. 1. Study of Life Time of Muons Author: Frank Researcher: Frank Nati
2. 2. Data Source • Detector ID 6818 from Gleenbrook North High School. • Data: Sep 19th 2015
3. 3. Verification Steps
4. 4. Theoretical Ananysis • Equation for decay: • Cosmicray e-lab program: x-axis: t y-axis: dN/dt Take the differential form: 0 t NdN e dt      0 t N N e   
5. 5. Cosmicray e-lab result
6. 6. Revision---Matlab • Input data into Excel then into Matlab
7. 7. Revision---Matlab • Draw a histogram
8. 8. Revision---Matlab • Draw best-fitting line---change equations • Define y= , then , we take ln on both sides: dN dt 0 t N y e      0 1 ln ln( ) * N y t    
9. 9. Revision---Matlab Y=-0.38*x+2.7
10. 10. Calculation • = -0.38 • = 2.63 μs 1   
11. 11. Verification • Wiki page: https://en.wikipedia.org/wiki/Muon
