Orders of Magnitude Improved Cyclotron-Mode Cooling for Non-Destructive Spin Quantum Transition Spectroscopy with Single Trapped Antiprotons

B. M. Latacz, M. Fleck, J. I. Jaeger +21

We demonstrate efficient sub-thermal cooling of the modified cyclotron mode of a single trapped antiproton and reach particle temperatures below mK in p…

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,…

A 16 Parts per Trillion Comparison of the Antiproton-to-Proton q/m Ratios

M. J. Borchert, J. A. Devlin, S. E. Erlewein +20

The Standard Model (SM) of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance of matter and antimatter…

Ultra thin polymer foil cryogenic window for antiproton deceleration and storage

B. M. Latacz, B. P. Arndt, J. A. Devlin +21

We present the design and characterisation of a cryogenic window based on an ultra-thin aluminised PET foil at T < 10K, which can withstand a pressure difference larger than 1bar a…

Production of antihydrogen atoms by 6 keV antiprotons through a positronium cloud

P. Adrich, P. Blumer, G. Caratsch +61

We report on the first production of an antihydrogen beam by charge exchange of 6.1 keV antiprotons with a cloud of positronium in the GBAR experiment at CERN. The antiproton beam…

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…
