  2. Background Info • A muon is an elementary particle that is a very heavy electron • Lifetime of 2.2 microseconds, makes up more then half of cosmic radiation • Created when cosmic rays (mostly protons) from deep space hit the earth’s atmosphere at about 15,000m

  3. Experiment Description • Two Photomultiplier tubes (PMT), a scintillator panel and a QNET board are sent up to 1000 ft to detect a change in the rate of muons • Hypothesis- more muons will be detected at a higher altitude

  5. Procedure • A gondola was constructed and attached to a weather balloon and lifted to 1000 ft. • Data was taken for 30 min. • A XBEE transmitter transmits the data to a receiver on the ground. • The counts are graphed and analyzed

  6. TheData • At ground level the rate was 2.6 counts per minute • At 766ft the rate was 94.1 counts per minute • We did have a very large discrepancy between the rates from the ground and at 766ft • About 36 times more muons at 766ft than at ground level

  8. Conclusion • We checked the PMT and threshold voltages • For this test, the data is valid • If repeated, the data would probably change • To improve, we would take more sets of data to reduce the error and take an average
