✦ Synopsis

A technique enabling in situ measurements of the spectrum of X-ray tubes employed in mammographic screenings is described. The technique involves the use of a commercially available CCD camera and a set of metal foils and is particularly useful to perform a fast evaluation of the spectral properties of a Mo anode mammographic system operating at standard flux levels. A description of the detector calibration procedure is first given, followed by a discussion of the study and choice of an appropriate set of X-ray attenuation foils. Finally, the use of the system for a spectroscopic characterization of a mammographic system is reported.

Oxygen interaction of CdS-based gas sens

Oxygen interaction of CdS-based gas sensors with different stoichiometric compositions was studied by X-ray photoelectron spectroscopy (XPS) and thermal-desorption mass spectroscopy observations combined with conductivity measurements. Three different types of film with different atomic ratios of Cd/S were used in the study of oxygen chemisorption in a low-temperature range between 300 and 570 K. Spray pyrolysis was used for the deposition of the films on glass substrates; XPS and energy dispersive spectroscopy of X-ray together with atomic force microscopy and scanning electron microscopy were used for the characterization of the composition and structure of the films. It was possible to distinguish different temperature ranges for the thermal desorption of the different adsorbed oxygen species. A comparison of the data from XPS and mass-spectroscopy observations with conductance measurements allows to conclude that metallic surface atoms are responsible for different interactions of oxygen species with CdS surfaces.
