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…
The positronium hyperfine structure: Progress towards a direct measurement of the transition in vacuum
M. Heiss, G. Wichmann, A. Rubbia +1
We present the current status for the direct measurement of the positronium hyperfine structure using the $\text{2}^\text{3}\text{S}_\text{1} \rightarrow \text{2}^\text{1}\text{S}_…
