Producing long-lived Ps via laser excitation in magnetic and electric fields
S. Aghion, C. Amsler, M. Antonello +62
Producing positronium (Ps) in the metastable state is of interest for various applications in fundamental physics. We report here about an experiment in which Ps atom…
Upgrade of ASACUSA's Antihydrogen Detector
V. Kraxberger, C. Amsler, H. Breuker +35
The goal of the ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) CUSP experiment at CERN's Antiproton Decelerator is to measure the ground state hyperfine splitt…
Prospects for measuring the gravitational free-fall of antihydrogen with emulsion detectors
AEgIS Collaboration, S. Aghion, O. Ahlén +68
The main goal of the AEgIS experiment at CERN is to test the weak equivalence principle for antimatter. AEgIS will measure the free-fall of an antihydrogen beam traversing a moiré…
Analysis of electron-positron momentum spectra of metallic alloys as supported by first-principles calculations
P. Folegati, I. Makkonen, R. Ferragut +1
Electron-positron momentum distributions measured by the coincidence Doppler broadening method can be used in the chemical analysis of the annihilation environment, typically a vac…
SDR, EVC, and SDREVC: Limitations and Extensions
E. D. Hunter, C. Amsler, H. Breuker +34
Methods for reducing the radius, temperature, and space charge of nonneutral plasma are usually reported for conditions which approximate an ideal Penning Malmberg trap. Here we sh…
Minimizing plasma temperature for antimatter mixing experiments
E. D. Hunter, C. Amsler, H. Breuker +37
The ASACUSA collaboration produces a beam of antihydrogen atoms by mixing pure positron and antiproton plasmas in a strong magnetic field with a double cusp geometry. The positrons…
