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.

Magnet Data (top without magnets bottom with magnets) (error was 50 counts in 30 min) Counts in 30 minute trial TRIALSTRIALS

Total Counts In 90 Minutes

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
