The cylindrical triode-type accelerator GESA IV-m was built for the application of a radial converging pulsed electron beam to modify the surface of an anode tube. The experimental studies showed an anode current of only 80% of the emission current a

A new cylindrical electron accelerator with a revised design (1-m long cathode, new plasma cathode concept) was built and a first experimental study of its operation was performed. The cathode plasma is generated by uniformly distributed vacuum-arc d

The challenging demands of pulsed electron beam devices (such as the GESA device) with respect to their pulsed power supply have led to the development of a new semiconductor-based Marx generator. At a maximum output voltage of 120 kV and 600-A pulse

The corrosion behaviour of four different alumina-forming austenitic model alloys (Fe-Cr-Al-Ni based) in oxygen-containing molten Pb at 600 and 650 °C has been investigated. A thin protective oxide layer is formed on all alloys after 2000 h at 600

Three high entropy alloys (HEAs), based on Al-Cr-Fe-Ni-X (X: Cu, Ti or Nb), have been designed and prepared. The sample with Cu addition has formed FCC solid solutions while the other two have formed FCC matrix plus inter-metallic phases (B2-Ni(Al,Ti

Three 9 wt% Cr ferrite/martensite steels (two alloyed with Si) have been exposed to oxygen-controlled LBE at 550 and 600 °C, respectively. The passivating oxide scale consists of a spinel layer plus internal oxidation zone (IOZ). By adding Si, the t

Five Al-Cr-Fe-Ni based high entropy model alloys, mainly a mixture of FCC and BCC or single FCC phase, have been designed and prepared. The corrosion tests of as-cast alloys in oxygen-containing molten Pb show their promising corrosion resistances at

The performance of the converging electron beam generated in cylindrical triodes is systematically studied by particle-in-cell code simulations. Depending on the cathode and grid potentials applied, different operation regimes are identified. For low
