WebMar 17, 2024 · The helium emission spectrum in the EUV wavelength range is presented to show all the relatively strong EUV lines. A Maxwellian shape is assumed for the electron energy distribution, and a corona model is applied to evaluate the plasma parameters under low-pressure conditions. WebThe initial pressure in tank 2 is P1 = 1.2 bar, and the minimum pressure for a normal shock wave is found to be P2 = 1.35 bar. Since the minimum pressure for a normal shock wave is higher than the initial pressure in tank 2, a normal shock wave cannot exist in the pipe from tank 2 to the outside environment under any conditions.
