Journal ArticleDOI
Doppler Reflectometry for the Investigation of Propagating Density Perturbations
TL;DR: Doppler reflectometry is characterized by a finite tilt angle of the probing microwave beam with respect to the normal onto the cutoff surface as mentioned in this paper, where the signal intensity contains information about the perturbation amplitude.
Journal ArticleDOI
Heterodyne methods in millimetre wave plasma diagnostics with applications to ECE, interferometry and reflectometry
TL;DR: In this paper, the basic principles of heterodyne techniques are introduced and various components of a heterogeneous system are summarized, and the diagnostic applications in ECE, interferometry and reflectometry are discussed after introducing the diagnostic principles.
Journal ArticleDOI
Heidelberg-Moscow ββ experiment with 76 Ge: Full setup with five detectors
M. Günther,J. Hellmig,G. Heusser,M. Hirsch,Hans Volker Klapdor-Kleingrothaus,Berenike Maier,H. Päs,F. Petry,Y. Ramachers,H. Strecker,M. Völlinger,A. Balysh,S. T. Belyaev,A. Demehin,A. Gurov,I. Kondratenko,D. Kotel'nikov,V. I. Lebedev,A. Müller +18 more
TL;DR: The full setup of the Heidelberg-Moscow double \ensuremath{\beta} decay experiment is presented in this paper, which gives at present the most stringent upper bound, improving the neutrino mass limit into the sub-eV range.
Journal ArticleDOI
Major results from the stellarator Wendelstein 7-AS (Review Article)
M. Hirsch,J. Baldzuhn,C. D. Beidler,R. Brakel,R. Burhenn,Andreas Dinklage,H. Ehmler,M. Endler,V. Erckmann,Y. Feng,J. Geiger,L. Giannone,G. Grieger,P. Grigull,H. J. Hartfuss,D. A. Hartmann,R.

TL;DR: Wendelstein 7-AS was the first modular stellarator device to test some basic elements of stellarator optimization: a reduced Shafranov shift and improved stability properties resulted in β-values up to 3.4% as discussed by the authors.
Journal ArticleDOI
Supersymmetry and Neutrinoless Double Beta Decay
TL;DR: This work considers the minimal supersymmetric standard model (MSSM) with explicit Rp / terms in the superpotential (Rp) and investigates the mechanism of 0��� decay induced by superparticle exchange.
