The inertial fusion program requires knowledge of the amount of gas contained within Microshell targets. Beta particles from the decay of tritium in a DT-filled shell interact with the glass walls producing x-rays. Measurement of the intensity of the emitted x-rays yields information on tritium content and indirectly on total gas pressure in the shell. The x-ray yield is influenced by fill pressure, shell wall thickness, shell composition, and shell diameter. Experimental results have been obtained relating effects of fill pressure as well as glass composition on x-ray production. X-ray spectra have been obtained with a Si(Li) detector. A qualitative measure of glass composition is obtained from the spectra: Si, Na, Al, K, and Ca lines are clearly visible when present.
