In cathode-ray tubes, high current densities at relatively low operating temperatures can be achieved with dispenser cathodes containing scandium oxide. The surface structure and precise emission mechanism of the scandate cathode are not known. The s

The effect of sputtering and Sc supply rate for Re-coated scandate cathodes is investigated by scanning Auger measurements (SAM) and electron emission measurements. It is shown that during the first few hours of operation, the Sc supply rate is suffi

The calorimetric glass transition in amorphous Pd40Ni40P20 was measured in a series of Differential Scanning Calorimetry (DSC) experiments. Especially the exact shape and position of the glass-transition peak were examined after different pre-anneali

Structure changes in amorphous ${\mathrm{Pd}}_{52}$${\mathrm{Ni}}_{32}$${\mathrm{P}}_{16}$ upon relaxation were modeled by means of reverse Monte Carlo (RMC) simulations using neutron-diffraction data from M. Schaal, P. Lamparter, and S. Steeb [Z. Na

The activation volume for diffusion of ion-implanted Au in the amorphous metal Pd40Ni40P20 has been determined from the pressure dependence of the diffusivity. Samples, in the well-relaxed state at 563 K prior to implantation, were annealed at 563.0

Two sets of experimental data for structural relaxation in amorphous PdNi P are analysed in detail. Differential scanning calorimetry measurements for Pd40Ni20P20, can be described to a great degree of detail by the free-volume theory, using paramete

Measurements of the diffusivity of ion-implanted Au in amorphous Pd 40 Ni 40 P 20 have been performed at temperatures just below the glass-transition temperature. Concentration probles before and after annealing were determined with Rutherford-backsc

A test of a proposed connection between the free volume in amorphous Pd40Ni40P20 and the glass transition is performed by accurately measuring the DSC traces of as-quenched and pre-annealed samples. It was found that the effect of pre-anneals at two
