Interaction of relativistically intense laser pulses with long-scale near critical plasmas for optimization of laser based sources of MeV electrons and gamma-rays

Autor: O N Rosmej, N E Andreev, S Zaehter, N Zahn, P Christ, B Borm, T Radon, A Sokolov, L P Pugachev, D Khaghani, F Horst, N G Borisenko, G Sklizkov, V G Pimenov

Publikováno v: New Journal of Physics, Vol 21, Iss 4, p 043044 (2019)

Experiments were performed to study electron acceleration by intense sub-picosecond laser pulses propagating in sub-mm long plasmas of near critical electron density (NCD). Low density foam layers of 300–500 μ m thickness were used as targets. In

An incubation study of GHG flux responses to a changing water table linked to biochemical parameters across a peatland restoration chronosequence

Autor: R. Hermans, N. Zahn, R. Andersen, Y.A. Teh, N. Cowie, J.-A. Subke

Publikováno v: Mires and Peat, Vol 23, Iss 08, Pp 1-18 (2019)

Large areas of northern peatlands have been drained and afforested with conifers in the 20th century. This has led to changes in the hydrology of the peatlands, the quality and quantity of organic matter inputs and soil microbial communities, which a

Investigating sentiments in Brazilian and German Blogs

Autor: Nina N. Zahn, Greice Pinho Dal Molin, Soraia Raupp Musse

Publikováno v: Journal of the Brazilian Computer Society. 28:96-103

Social interactions have changed in recent years. People post their thoughts, opinions and sentiments on social media platforms more often, through images and videos, providing a very rich source of data about population of different countries, commu

High-current laser-driven beams of relativistic electrons for high energy density research

Autor: V. A. Panyushkin, P. Neumayer, M. M. Günther, N.G. Borisenko, N Zahn, A. V. Kantsyrev, Nikolay Andreev, O. N. Rosmej, X. F. Shen, Alexander Pukhov, P. Tavana, V. S. Popov, M. Gyrdymov, A. Skobliakov, A. V. Bogdanov, Fabrizio Consoli, S. Zähter

Publikováno v: Plasma Physics and Controlled Fusion

We report on enhanced laser driven electron beam generation in the multi MeV energy range that promises a tremendous increase of the diagnostic potential of high energy sub-PW and PW-class laser systems. In the experiment, an intense sub-picosecond l

Publikováno v: AECL Nuclear Review. 2:17-26

In 2009 May, the National Research Universal (NRU) calandria leaked. During the next year, the calandria was inspected with six new Non-Destructive Evaluation (NDE) techniques to determine the extent of the corrosion, repaired, and finally the repair
