  1. The Medium Rares Measure with MoNA MoNA detects particles by picking up light produced in a scintillating material with photomultiplier tubes. Patricia Hanlan- Detroit Country Day KlintKanopka- Academy at Palumbo (Philadelphia) Gordon Loveland- University School (Cleveland) Day One We used MoNA and an oscilloscope to observe cosmic rays and neutrinos from a Californium Source. After a calibration, we tried to locate a source of unknown position. Conclusions: Taking data with an oscilloscope is really hard and our results did not win us any prizes. How cave physicists analyzed data. Difference in pulse arrival time and normalized pulse height versus source location. Day Two Conclusions: Using SpecTcl, we were able to determine the location of the source within 0.008m. Using the data analysis package SpecTcl, we repeated the previous day’s experiment with greatly increased accuracy. Hard at work in the Data U Cosmic ray energy spectrum within SpecTcl Day Three Locating the missing Californium Conclusions: We identified limits of the detector and observed the angle/energy correlation. Armed with 10 hours of overnight cosmic ray data, we used SpecTcl to investigate the incident angle of incoming muons, the speed of the cosmic muons and the relationship between energy deposited and distance traveled in the scintillating array. Our crowning achievement, the correlation between incident angle and energy deposited. Calculating muon speed Our observed and expected angular distributions. The missing counts are due to detector size. …is a magic number. Was that Lithium 5?
