RESEARCH IN TURBULENT WAKES
Abstract
Data on jet turbulence are being obtained steadily with the photospecto-correlator and the bistatic microwave probe. The two most interesting results have been the discovery of the null in the microwave signal scattered through 90 deg from an overdense plasma and the discovery that grid insertion demodulates the jet turbulence in a selective manner. The possibility of demodulating an RV'S oscillation superimposed on its wake is an interesting prospect. The laser source for the shadowgraph system is expected in-house in January 1966. Its field of view (8 in.) should be ideal in view of the photometric finding that the integral scale of the jet is of the order of 4 inches. Gun development has progressed to the point where data rounds may soon be obtained using the instruments developed at CARDE. The necessity of enhancing the wake ionization to provide sufficient signal amplitude for some of the instruments is becoming apparent.
