PPT-Constructing and calibrating a neutron detector using cosmi

Matthew Mendonca Woodside High School Mentor Dr Doug Higinbotham and Lawrence Selvy Abstract The particles that make up the nucleus of an atom are so infinitesimally small that it takes a detector of large magnitude in order to predict where protons and neutrons are located This certain device requires the construction and utilization of onemeterlong rectangular plastic bars called scintillators Attached to the left and right ends of each bar are Photomultiplier Tubes PMTs and bases with outlets for high voltage and signal wires In experiments there is a thick wall of lead positioned in front of the detector which excludes nearly all charged particles and permits primarily neutrons to enter and react with the nuclei inside the bars When charged particles do pass through the scintillators photons are released and bounce around until they reach a light guide and are collected by the PMTs Within these there is liberation of electrons which in turn provide an analog signal to the electronics A data acquisition system DAQ comprised of ADCs AnalogtoDigital Converters and TDCs TimetoDigital Converters then store the data into files for later replay and analysis By doing so we can better measure the type of particle detected its trajectory and the amount of energy that it deposits To ensure that these complex apparatuses are working at an acceptable level scientists manipulate the constant flux 100 particlesm. syntheticapcom When previewing video output its important that the video monitor be calibrated Proper monitor calibration ensures that what you see today will match what you see tomorrow and that the judgements and decisions you make based on what yo Varun Bhalerao.
