This is the background on the name of the device and what it is actually doing:

Called a Hodoscope (from the Greek “hodos” for way or path, and “skopos:” an observer) it is a type of detector commonly used in particle physics that make use of an array of detectors to determine the trajectory of an energetic particle.

When a muon flies through the detector, it will trigger two tubes simultaneously.  By graphing which of the two tubes are triggered on an array of 81 LEDs, it gives an indication that a muon was detected as well as where it struck.

Well that was sciencetastic!  What types of applications would this be used for can you guess?

We hope you liked the video and big thanks to Muon Ray for the footage.
