I worked with Trevor Daino and Arpad Voros to design a new way to detect the trajectory of high energy muon particles for the purposes of muon tomography. We had read a few papers about how vaccuum tubes were being used to measure the trajectory of muons to capture images of materials.
We were fascinated by the new technology and reached out to a professor to learn more about building our own muon tomography device. We crafted a design and he told us it would cost over a million dollars!
So we scrapped the design and set out to build a new device to use muonss for imaging, that would be within our price range of a few hundred dollars.
Our idea was to have 4 layers of plastic scintillators, each paired with a silicon photomultiplier array, to triangulate the muon's position at each layer. Then we could use the change in positions from layer to layer to find the muon's trajectory.
We planned to put an object in the middle of the device (between two top layers and two bottom layers) so that we could measure the deflection of the muon after penetrating through the object (by comparing the muon's trajectory before and after hitting the object).
We worked every day after school for months designing, soldering, and sawing in my friend's garage to create a working model. We tested our protoype using UV light and built a muon scattering simulation for a scaled up version of the device in java and matlab.
Eventually we presented our findings at the Intel International Science and Engineering Fair (ISEF) where we placed 3rd in the Physics and Astronomy category!
