Design and Commissioning of a Deuterium-Tritium Gas Delivery System for Muon Catalyzed Fusion in a Diamond Anvil Cell
Elena Koukina, Cody Fagan, Christopher Robert Shmayda +46
We report the design, commissioning, and operation of deuterium-deuterium (DD) and deuterium-tritium (DT) gas delivery systems developed to load a diamond anvil cell (DAC) beam tar…
Synthesis of a high intensity, superthermal muonium beam for gravity and laser spectroscopy experiments
Jesse Zhang, Aldo Antognini, Marek Bartkowiak +8
The universality of free fall, a cornerstone of Einstein's theory of gravity, has so far only been tested with neutral composite states of first-generation Standard Model (SM) part…
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…
Geant4 simulation of the PSI LEM beam line: energy loss and muonium formation in thin foils and the impact of unmoderated muons on the SR spectrometer
Kim Siang Khaw, Aldo Antognini, Paolo Crivelli +5
The PSI low-energy SR spectrometer is an instrument dedicated to muon spin rotation and relaxation measurements. Knowledge of the muon beam parameters such as spatial, kinetic e…
Observation of positronium annihilation in the 2S state: towards a new measurement of the 1S-2S transition frequency
D. A. Cooke, P. Crivelli, J. Alnis +8
We report the first observation of the annihilation of positronium from the 2S state. Positronium (Ps) is excited with a two-photon transition from the 1S to the 2S state where its…
Muonium emission into vacuum from mesoporous thin films at cryogenic temperatures
A. Antognini, P. Crivelli, T. Prokscha +9
We report on Muonium (Mu) emission into vacuum following μ+ implantation in mesoporous thin SiO2 films. We obtain a yield of Mu into vacuum of (38\pm4)% at 250 K temperature and (2…
