THE DESIGN AND CONSTRUCTION OF A LUMINOUS SHOCK TUBE FOR SPECTROSCOPIC INVESTIGATIONS OF HIGHTEMPERATURE GASES; PRELIMINARY RESULTS FOR SOME ELEMENTS OF ASTROPHYSICAL INTEREST,
Abstract
The application of the shock tube to laboratory astrophysical studies is discussed, with particular regard to the experimental determination of atomic and molecular transition probabilities. The construction of a two-inch stainless-steel shock tube and its associated mechanical and electronic equipment is described. The measurement of the pressure and velocity history of the gas flow as well as radiation measurements behind the reflected shock are discussed. A comparison of hydrodynamic observations with theoretically derived values indicates that, for the McMillin shock tube, there are deviations from accepted shock-tube behavior. Excitation temperatures computed using the emission lines of neutral iron, are found to be very much lower than can be accounted for by present shock-tube theories. (Author)
