Book Description
The shock tube and auxiliary equipment are described in AD-410 569. Modifications and additions to the equipment are discussed. The theory of the formation of spectrum lines, applicable to shock-tube spectroscopy, is developed. A temperature behind the reflected shock is computed by a line reversal method which is in good agreement with previously measured excitation temperatures. (Author).

Book Description
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).

Book Description
The design, construction and development of a shock tube facility is described. The spectroscopic, ultrasonic and electronic equipment associated with the shock tube is also described. Simultaneous time resolved photographic and photoelectric records of reflected shock spectra are illustrated. Gas temperature measurement by an ultrasonic pulse method is discussed in addition to a proposed electron beam technique for gas density measurements. (Author).

Book Description
A brief description is given of the shock tube facility and associated measuring equipment. The theory of radiative transfer in a uniform gas is developed with reference to shock tube spectroscopic measurements. Gas temperatures behind reflected shocks were measured simultaneously by a line reversal technique and by an ultrasonic probe method. The average temperatures agree to within 3-1/2%. Measurements of shock gas density were made with an electron beam gas densitometer. A set of preliminary gf values were determined for ten CrI spectral lines distributed over three multiplets.
