Shahab Khan and Peter Torres Linearity Test Shahab Khan and Peter Torres

Objective A linearity test is performed to determine if there is a direct response from the cells and PMT To rule out the possibility of light leakage, light saturation, or any other problems By changing the input light incident upon the cells, we should see a linear output response

Procedure Used discrete pulsed LED with settings: f = 100 Hz, Amplitude = {8,10,12,14,16}V Observed output current from ammeter as input amplitude was varied Took 500 measurements for each LED input Repeated procedure for PMT Voltage 1400, 1500, 1600, 1700
