Positron plasma diagnostics and temperature control for antihydrogen production
ATHENA Collaboration, M. Amoretti, C. Amsler +29
Production of antihydrogen atoms by mixing antiprotons with a cold, confined, positron plasma depends critically on parameters such as the plasma density and temperature. We discus…
Production of Cold Antihydrogen with ATHENA for Fundamental Studies
ATHENA Collaboration, A. Kellerbauer, M. Amoretti +33
Since the beginning of operations of the CERN Antiproton Decelerator in July 2000, the successful deceleration, storage and manipulation of antiprotons has led to remarkable progre…
The First Cold Antihydrogen
M. C. Fujiwara, M. Amoretti, C. Amsler +29
Antihydrogen, the atomic bound state of an antiproton and a positron, was produced at low energy for the first time by the ATHENA experiment, marking an important first step for pr…
Production of Slow Protonium in Vacuum
N. Zurlo, M. Amoretti, C. Amsler +28
We describe how protonium, the quasi-stable antiproton-proton bound system, has been synthesized following the interaction of antiprotons with the molecular ion H in a nested…
Three Dimensional Annihilation Imaging of Antiprotons in a Penning Trap
M. C. Fujiwara, M. Amoretti, G. Bonomi +28
We demonstrate three-dimensional annihilation imaging of antiprotons trapped in a Penning trap. Exploiting unusual feature of antiparticles, we investigate a previously unexplored…
Evidence For The Production Of Slow Antiprotonic Hydrogen In Vacuum
N. Zurlo, M. Amoretti, C. Amsler +28
We present evidence showing how antiprotonic hydrogen, the quasistable antiproton-proton (pbar-p) bound system, has been synthesized following the interaction of antiprotons with t…
Towards European Standards for Quantum Technologies
O. van Deventer, N. Spethmann, M. Loeffler +21
The Second Quantum Revolution facilitates the engineering of new classes of sensors, communication technologies, and computers with unprecedented capabilities. Supply chains for qu…
ATHENA -- First Production of Cold Antihydrogen and Beyond
ATHENA Collaboration, A. Kellerbauer, M. Amoretti +33
Atomic systems of antiparticles are the laboratories of choice for tests of CPT symmetry with antimatter. The ATHENA experiment was the first to report the production of copious am…
First Production and Detection of Cold Antihydrogen Atoms
M. C. Fujiwara, M. Amoretti, C. Amsler +29
The ATHENA experiment recently produced the first atoms of cold antihydrogen. This paper gives a brief review of how this was achieved.
Cold-Antimatter Physics
ATHENA Collaboration, M. Amoretti, C. Amsler +33
The CPT theorem and the Weak Equivalence Principle are foundational principles on which the standard description of the fundamental interactions is based. The validity of such basi…
