Testing Quantum Gravity with Gravitational Waves from the ringdown of binary Black Holes coalescences: A New Frontier in Fundamental Physics
Marco Danilo Claudio Torri, Fulvio Ricci, Marco Giammarchi +3
The observation of gravitational waves emitted during the merging phase of compact binary coalescing objects has opened a new field of investigation in fundamental physics. It is n…
Optimizing Antihydrogen Production via Slow Plasma Merging
E D Hunter, M Bumbar, C Amsler +29
We measure the time-dependent temperature and density distribution of antiprotons and positrons while slowly combining them to make antihydrogen atoms in a nested Penning-Malmberg…
Measured Properties of an Antihydrogen Beam
E. D. Hunter, M. Bumbar, C. Amsler +29
We report a factor of increase in the antihydrogen beam intensity downstream of ASACUSA's Cusp trap: atoms detected per -minute run. The beam contains many Rydberg…
Towards a Study of Low Energy Antiproton Annihilations on Nuclei
Viktoria Kraxberger, Marcus Bumbar, Angela Gligorova +30
A study of antiproton annihilations at rest on thin solid targets is underway at the ASACUSA facility, which now features a dedicated beam line for slow extraction at 250 eV. The e…
Antiproton annihilation at rest in thin solid targets and comparison with Monte Carlo simulations
Claude Amsler, Horst Breuker, Marcus Bumbar +33
The mechanism of antiproton-nucleus annihilation at rest is not fully understood, despite substantial previous experimental and theoretical work. In this study we used slow extract…
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,…
Towards the formation of a positronium coherent beam
M. Sacerdoti, V. Toso, G. Vinelli +5
Positronium (Ps) has emerged as a promising test particle within the QUPLAS collaboration for investigating the gravitational effect. In this work, we present a novel approach to g…
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…
A large-momentum-transfer matter-wave interferometer to measure the effect of gravity on positronium
G. Vinelli, F. Castelli, R. Ferragut +7
This paper reports the study of a new interferometric configuration to measure the effect of gravity on positronium. A Mach-Zehnder matter-wave interferometer has been designed to…
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…
A cryogenic tracking detector for antihydrogen detection in the AEgIS experiment
C. Amsler, M. Antonello, A. Belov +55
We present the commissioning of the Fast Annihilation Cryogenic Tracker detector (FACT), installed around the antihydrogen production trap inside the 1 T superconducting magnet of…
The SABRE project and the SABRE PoP
M. Antonello, E. Barberio, T. Baroncelli +46
SABRE aims to directly measure the annual modulation of the dark matter interaction rate with NaI(Tl) crystals. A modulation compatible with the standard hypothesis in which our Ga…
