Bias Voltage: The signal mean was extracted for five different runs at five different detector bias voltages and then plotted. As the bias voltage is increased, the silicon depletion, and with it the signal height, should rise quickly to full depletion, between 10 and 15 volts, and then plateau. Ideally, this should result in a logarithmic curve; our data, while not conclusive, do show the expected behavior in the voltage range covered.
