C graphs
 Our C detector at the time was not
functioning properly (small light leak) so we
decided to take it out of our magnet trials to
simplify it. We later fixed the detector and
recalibrated it, and it is now functioning fine.
Hypothesis
 We thought that if we put up a magnetic field
above the detector then the field could curve
muons and other particles off the path of
hitting all 3 detectors.

No Magnets
With Magnets
Results
 Our magnet array did not deflect many
muons, but it increased our count rate. We
are thinking about why this would happen
but still have not found an answer
Next Step
 If we were to continue out experiment to find
out why we got more counts we would…
 Change the orientation of the magnet box.
 Change the magnetic field
 And make a better structure to angle our
detectors
Directional experiment
 We put 2 detectors on a box 1 foot apart and
then tilted it to find out where a majority of
muons were coming from in orders to see if
we were curving muons into out detectors
with our magnets
 We found that many more muons were
coming from above us rather than from an
angle
Data
Electron theory
 We thought that it was possible that we were
curving particles with less momentum int out
detectors
