Question

7. Why do we allow the gas to flow (as opposed to filling the chamber and shutting off the gas or using a sealed detector)? 8. With the proportional counter, if we had used an alpha/beta mixed source to develop the counting curve, we would have seen two plateaus. Draw this ideal curve and explain what is happening to produce the plateaus and the general shape of the curve. Which plateau (alpha or beta) occurs first? With some detail, explain why it occurs first. Using a dashed line, plot the general shape of your counting curve and explain any discrepancies from the ideal.
