PhD: 2005, Reactor Institute Delft, Delft University of Technology, The Netherlands
Thesis: The Time Dependent Midway Monte Carlo Method for Borehole Logging Applications
Currently working at: Forschungszentrum Rossendorf,Institute of Safety Research, Dresden, Germany
Current Research Areas:
• Time Dependent Monte Carlo for Reactor Dynamics
• variance reduction optimisation for the collimator of the ELBE nToF setup
• detector simulations for the nTof measurements
Connection to EUROTRANS:
• Future contributor
• ADS simulations

ELBE: Electron Linear accelerator with high Brilliance and low Emittance
The superconducting electron accelerator ELBE

The liquid-lead radiator
• Electron beam pulse length t = 5 ps
• Small neutron radiator volume - short neutron pulses, well-determined in time by e- beam time structure - minimize scattering in radiator & thermal neutron background
• Large enough for reasonable intensity - optimal volume 1 cm3
- neutron pulse width < 2 ns - En resol E/E < 1 % at 4 m flight path
• Thermal load up to 25 kW liquid Pb radiator
• Water-cooled via InGaSn heat exchanger
