Bright betatron radiation from direct-laser-accelerated electrons at moderate relativistic laser intensity
O. N. Rosmej, X. F. Shen, A. Pukhov +8
Direct laser acceleration (DLA) of electrons in a plasma of near critical electron density (NCD) and associated synchrotron-like radiation are discussed for moderate relativistic l…
New insights in laser-generated ultra-intense gamma-ray and neutron sources for nuclear applications and science
M. M. Günther, O. N. Rosmej, P. Tavana +7
Ultra-intense MeV photon and neutron beams are indispensable tools in many research fields such as nuclear, atomic and material science as well as in medical and biophysical applic…
Ultra high precision refractive index measurement of Si at -ray energies up to 2 MeV
M. M. Günther, M. Jentschel, A. J. Pollitt +2
The refractive index of silicon at -ray energies from 181 - 1959 keV was investigated using the GAMS6 double crystal spectrometer and found to follow the predictions of the clas…
Relativistic electron Wigner crystal formation in a cavity for electron acceleration
Johannes Thomas, Marc M. Günther, Alexander Pukhov
It is known that a gas of electrons in a uniform neutralizing background can crystallize and form a lattice if the electron density is less than a critical value. This crystallizat…
Exploring the multi-humped fission barrier of 238U via sub-barrier photofission
L. Csige, D. M. Filipescu, T. Glodariu +10
The photofission cross-section of 238U was measured at sub-barrier energies as a function of the gamma-ray energy using, for the first time, a monochromatic, high-brilliance, Compt…
A Quantal, Partially Ordered Electron Structure as a Basis for a γFree Electron Laser (γ-FEL)
D. Habs, M. M. Günther, S. Karsch +2
When a rather cold electron bunch is transported during laser bubble acceleration in a strongly focusing plasma channel with typical forces of 100 GeV/m, it will form partially ord…
Seeded quantum FEL at 478 keV
M. M. Günther, M. Jentschel, P. G. Thirolf +2
We present for the first time the concept of a seeded γ quantum Free-Electron-Laser (QFEL) at 478 keV, which has very different properties compared to a classical. The basic concep…
Nuclear photonics at ultra-high counting rates and higher multipole excitations
P. G. Thirolf, D. Habs, D. Filipescu +5
Next-generation gamma beams beams from laser Compton-backscattering facilities like ELI-NP (Bucharest)] or MEGa-Ray (Livermore) will drastically exceed the photon flux presently av…
Nuclear Photonics
D. Habs, M. M. Guenther, M. Jentschel +1
With new gamma-beam facilities like MEGa-ray at LLNL (USA) or ELI-NP at Bucharest with 10^13 g/s and a bandwidth of Delta E_g/E_g ~10^-3, a new era of g-beams with energies <=20 Me…
The Refractive Index of Silicon at Gamma Ray Energies
D. Habs, M. M Günther, M. Jentschel +1
The index of refraction n(E_γ)=1+δ(E_γ)+iβ(E_γ) is split into a real part δand an absorptive part β. The absorptive part has the three well-known contributions to the cross section…
Bounds on new Majoron models from the Heidelberg-Moscow-Experiment
A. Balysh
In recent years several new Majoron models were invented to avoid shortcomings of the classical models while leading to observable decay rates in double beta experiments. We give t…
