Abstract
Abstract : We report progress in work on a cryogenic acoustic microscope. Results in liquid argon and nitrogen at about 4300 angstrom wavelength are discussed. Images of gratings and integrated circuits are presented as examples of resolution and contrast. Work on producing effective matching layers to improve acoustic power transfer between solids and helium is summarized. Finally we present images taken in superfluid helium held at 1.95 degrees K. A wavelength of 3600 angstrom was attained, the shortest wavelength ever achieved in an acoustic microscope. (Author)
