Acceptance and resolution simulation studies for the dielectron spectrometer HADES at GSI
(1996)Design studies for a second generation dilepton spectrometer to be built at the SIS accelerator of GSI Darmstadt are presented. The basic design parameters of this system are specified and the different detector components ...

Deposition and characterisation of TiAlBN coatings produced by direct electron-beam evaporation of Ti and Ti-Al-B-N material from a twin crucible source
(1999)TiAlBN coatings were synthesised by evaporating Ti and hot isostatically pressed TiAl0.68B3.67N2.44 material from a twin crucible source in an Ar plasma at 450°C. A combination of optical emission spectroscopy and partial ...

Dielectron production in C12+C12 collisions at 2AGeV with the HADES spectrometer
(2007)The invariant-mass spectrum of e+e- pairs produced in C12+C12 collisions at an incident energy of 2 GeV per nucleon has been measured for the first time. The measured pair production probabilities span over 5 orders of ...

The effect of boron additions on the tribological behaviour of TiN coatings produced by electron-beam evaporative PVD
(1999)TiN coatings containing small amounts of boron were synthesized by electron beam evaporating a Ti-B alloy material from a single crucible source into a plasma comprising Ar or an Ar/N2 mixture at a substrate temperature ...

Electron spectroscopic studies of nanocomposite PVD TiAlBN coatings
(2002)A range of TiAlBN coatings have been deposited by electron beam evaporation and the optimised composition exhibits a 150% improvement over single phase TiAlN coatings in drilling tests. The coatings have been analysed by ...

Evaluating the microstructure and performance of nanocomposite PVD TiAlBN coatings
(2002)Physical vapour deposition (PVD) TiAlBN coatings can exhibit excellent wear resistance, with optimised coating compositions demonstrating a 150% increase in lifetime compared to standard TiAlN coatings in wet-cutting drill ...

Partially yttria-stabilized zirconia coatings produced under plasma-assisted EBPVD with bipolar pulsed bias and under electron bombardment-assisted positive bias conditions
(1997)Previous research using radio frequency (rf) plasma-assisted electron beam (EB) PVD to deposit partially yttria-stabilized zirconia (PYSZ) thermal barrier coatings has shown the benefits of this method in terms of structure ...
