Demonstration of Muon-Beam Transverse Phase-Space Compression
A. Antognini, N. J. Ayres, I. Belosevic +16
We demonstrate efficient transverse compression of a 12.5 MeV/c muon beam stopped in a helium gas target featuring a vertical density gradient and crossed electric and magnetic fie…
Roadmap on STIRAP applications
Klaas Bergmann, Hanns-Christoph Nägerl, Cristian Panda +31
STIRAP (Stimulated Raman Adiabatic Passage) is a powerful laser-based method, usually involving two photons, for efficient and selective transfer of population between quantum stat…
muCool: A novel low-energy muon beam for future precision experiments
I. Belosevic, A. Antognini, Y. Bao +15
Experiments with muons () and muonium atoms () offer several promising possibilities for testing fundamental symmetries. Examples of such experiments include sea…
muCool: A next step towards efficient muon beam compression
A. Antognini, Y. Bao, I. Belosevic +15
A novel device to compress the phase space of a muon beam by a factor of with a efficiency is under development. A surface muon beam is stopped in a helium gas…
Multi-pass amplifiers with self-compensation of the thermal lens
Karsten Schuhmann, Klaus Kirch, Miroslaw Marszalek +7
We present a novel architecture for a multi-pass amplifier based on a succession of optical Fourier transforms and short propagations that shows a superior stability for variations…
Excitation of positronium from 2S to 20P state
M. W. Heiss, G. Wichmann, B. Radics +1
We report the observation of positronium excitation from the 2S to the 20P state. The Rydberg positronium atoms fly a distance of 40 mm before being field ionized and detected in a…
