Abstract : Activities regarding the design, construction and testing of equipment necessary for sample preparation and the inelastic electron tunneling spectrometer are described in detail. To successfully prepare a tunnel junction the supplied vacuum had to be made functional and then modified so that the following functions could be performed: (1) metal evaporation, (2) metal oxidation by glow discharge and (3) oxide contamination through bleed-in devices. Many of the difficulties encountered and the procedures used to eliminate them are discussed. Experimental tunnel junction spectral data are included and discussed in view of existing literature.
