The payload will be launched on August 21st, 2017 during the solar eclipse. By sending it during the eclipse we can determine if the majority of muons are from extrasolar sources. The payload will have the original design of three detectors. In future payload launches, the use of four or five Geiger counters could be used. Since the Arduino Mega could not process five Geiger counters, a different circuit could be programmed for the coincidence counts. The cylindrical shape of the Geiger tube is most effective. Other aspects like the thickness of the cylinder or anode wire could be studied. Moving forward, I would test the design of the four Geiger counters. I would place a radioactive source near the tubes and record the number of counts made. Then, I would have the same set up but with three Geiger counters. I would compare the two and show that the four Geiger counters have a higher count.
