Sub-millimeter nuclear medical imaging with high sensitivity in positron emission tomography using beta-gamma coincidences
C. Lang, D. Habs, K. Parodi +1
We present a nuclear medical imaging technique, employing triple-gamma trajectory intersections from beta^+ - gamma coincidences, able to reach sub-millimeter spatial resolution in…
Ultrasmall divergence of laser-driven ion beams from nanometer thick foils
J. H. Bin, W. J. Ma, K. Allinger +11
We report on experimental studies of divergence of proton beams from nanometer thick diamond-like carbon (DLC) foils irradiated by an intense laser with high contrast. Proton beams…
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…
Transmission resonance spectroscopy in the third minimum of 232Pa
L. Csige, M. Csatlos, T. Faestermann +8
The fission probability of 232Pa was measured as a function of the excitation energy in order to search for hyperdeformed (HD) transmission resonances using the (d,pf) transfer rea…
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…
Introducing the Fission-Fusion Reaction Process: Using a Laser-Accelerated Th Beam to produce Neutron-Rich Nuclei towards the N=126 Waiting Point of the r Process
D. Habs, P. G. Thirolf, M. Gross +6
We propose to produce neutron-rich nuclei in the range of the astrophysical r-process around the waiting point N=126 by fissioning a dense laser-accelerated thorium ion bunch in a…
