Injection and capture of antiprotons in a Penning-Malmberg trap using a drift tube accelerator and degrader foil
C. Amsler, H. Breuker, M. Bumbar +33
The Antiproton Decelerator (AD) at CERN provides antiproton bunches with a kinetic energy of 5.3 MeV. The Extra-Low ENergy Antiproton ring at CERN, commissioned at the AD in 2018,…
Upgrade of the positron system of the ASACUSA-Cusp experiment
A. Lanz, C. Amsler, H. Breuker +35
The ASACUSA-Cusp collaboration has recently upgraded the positron system to improve the production of antihydrogen. Previously, the experiment suffered from contamination of the va…
Slow positron production and storage for the ASACUSA-Cusp experiment
D. J. Murtagh, C. Amsler, H. Breuker +35
The ASACUSA Cusp experiment requires the production of dense positron plasmas with a high repetition rate to produce a beam of antihydrogen. In this work, details of the positron p…
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…
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…
Cyclotron cooling to cryogenic temperature in a Penning-Malmberg trap with a large solid angle acceptance
C. Amsler, H. Breuker, S. Chesnevskaya +35
Magnetized nonneutral plasma composed of electrons or positrons couples to the local microwave environment via cyclotron radiation. The equilibrium plasma temperature depends on th…
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…
Phases and Quantum Phase Transitions in Anisotropic Antiferromagnetic Kitaev-Heisenberg- magnet
Animesh Nanda, Adhip Agarwala, Subhro Bhattacharjee
We study the Kitaev-Heisenberg- model with antiferromagnetic Kitaev exchanges in the strong anisotropic (toric code) limit to understand the phases and the intervening phase tra…
Measurement of the Principal Quantum Number Distribution in a Beam of Antihydrogen Atoms
B. Kolbinger, C. Amsler, S. Arguedas Cuendis +35
The ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) collaboration plans to measure the ground-state hyperfine splitting of antihydrogen in a beam at the CERN An…
Phases and Quantum Phase Transitions in an Anisotropic Ferromagnetic Kitaev-Heisenberg- Magnet
Animesh Nanda, Kusum Dhochak, Subhro Bhattacharjee
We study the spin- ferromagnetic Heisenberg-Kitaev- model in the anisotropic (Toric code) limit to reveal the nature of the quantum phase transition between the gapped $Z_2…
Progress Towards Ramsey Hyperfine Spectroscopy in ASACUSA
A. Nanda
This proceedings contribution reports on progress on the design of a Ramsey-type spectrometer that will be used for the spectroscopy of the ground-state hyperfine structure of both…
Antiproton beams with low energy spread for antihydrogen production
M. Tajima, N. Kuroda, C. Amsler +23
A low energy antiproton transport from the ASACUSA antiproton accumulation trap (MUSASHI trap) to the antihydrogen production trap (double cusp trap) is developed. The longitudinal…
Hyperfine spectroscopy of hydrogen and antihydrogen in ASACUSA
E. Widmann, C. Amsler, S. Arguedas Cuendis +31
The ASACUSA collaboration at the Antiproton Decelerator of CERN aims at a precise measurement of the antihydrogen ground-state hyperfine structure as a test of the fundamental CPT…
