  1. Muon Lifetime Eric Chu & Joseph St. Marie

  2. Goals of our Experience • Gain an understanding of electronics • Design and run a working muon experiment • Analyze data and improvement experiment • Run final experiment • Acquire data reading the lifetime of the muon to be close to 2.19µs.

  3. Understand the Electronics • How do we use the oscilloscope? • What is a scintillator? • How does the setup work?

  4. An Oscilloscope is…

  5. A Scintillator is…

  6. The Setup is…

  7. Preparation • Conversion Graph

  8. Conversion Graph

  9. Setup

  10. First Experiment • Started: June 25 at 16:00 • Ended: June 28 at 15:38

  11. Results

  12. Results Cont.

  13. Final Experiment • Started: July 2 at 12:45 • Ended: July 6 at 9:20

  14. Preparation • Coincidence graphs • Singles graphs • New power supply • Rearranging the setup

  15. Coincidence Graphs • Final Threshold Levels: • Scintillator A: 120.026 mV • Scintillator B: 200.110 mV • Scintillator C: 70.601 mV

  16. Coincidence Between Scintillators A & B (B fixed)

  17. Coincidence Between Scintillators A & B (A fixed)

  18. Coincidence Between Scintillators B & C (B fixed)

  19. Singles Graph • To see what kind of particles are coming through (distinguish between noise and “real” particles) • Get a better understanding of how threshold affects counts

  20. Scintillator A Singles

  21. Scintillator B Singles

  22. Scintillator C Singles

  23. Scintillator D Singles*

  24. New Setup
