Gas laser cells: stress analysis of cylindrical cells with radial injection of electrons

Description: The problem is to develop a design procedure for pressurized cylindrical excimer laser cells. Excitation of the pressurized laser gas is by a short pulse of high energy electrons injected through the cell wall. In traversing the wall, the electrons lose energy and heat the wall. Because of rapid gas heating, a shock wave is generated which produces an additional load on the wall.

Development of a Low Cost Versatile Method for Measurement of HTO and HT in Air

Description: A low cost, highly sensitive method for the measurement of HTO and HT in air has been developed. The air is first passed through an ethylene glycol bubbler to remove the HTO, then through a heated palladium catalyst where the HT gas is oxidized to HTO and collected in a second ethylene glycol bubbler. The tritium collected by the bubblers is measured by liquid scintillation counting. Recoveries of 95 to 100% with air flow up to 750 cm/sup/3 /min are routinely obtained. The sensitivity of the me… more
