Angle and Flux
The relationship between angle and flux
Josh Eisenman and Gia Resendiz


for outr experiment we compared flux and the angle at which detectors are orriented. As we predicted the decrease in angle results in a decrease in flux. it seems that there is a Sine sort of relationship between angle and flux and that the closer the angle is to 45 the greater the rate of change is observed in the flux patterns.



We know that cosmic rays come from deep within our solar system, maybe even futher. They penetrate the earth's atomosphere at speeds close to the speed of light. They decay once they enter earth's atmosphere and can sustain themselves for a shore amount due to time and distance dialation. Once they decay, it creates a shower of secondary particles that can go in every direction. We want to find out if there is a relationship between angle and flux, and if there is one, what is that relationship.



1.     Find the correct voltage for the Counters through the process of plateauing.

2.     Obtain a Muon telescope (to the right) that holds the 4 counters at a set distance and has the ability to change angles.

3.     Using a protractor find 90� and lock it into position.

4.     Gather data for at least 8 hours with Putty (Data collection program)

5.     Find geometry relative to the GPS unit location.

6.     Upload and analyze data using cosmic ray elab.

7.     Repeat steps 3 to 6, but this time with the angles of 60�, 45�, 30�, and 0�.


8.     Compare results and formulate conclusion. 



The data shows the decrease in the amount of flux whenever angle is decreased. the graphs below show the decrease in average flux as the angles decrease


Discussions & Conclusions

Based off of the data we analyzed we can conclude that there is a direct relationship between the angle at which a muon telescope is at and it�s registered flux. As angle decreases so does the flux. 

Some possible areas of improvement

More Time.

More angles tested.


Test multiple directions such as south, east, and west.
