We present a pulsed "e+kick" scheme for removing ions from a positron plasma, along with other plasma routines used by the ASACUSA-Cusp Collaboration for making antihydrogen in 2023 and 2024. We also report on selected antimatter mixing experiments from 2023. Antiprotons are introduced into a plasma of 4×10^6 positrons with variable RF heating and mixing speed. The effects of these variables on antihydrogen yield are interpreted in a way that is consistent with theoretical predictions. Our observations provide general guidance for stable antihydrogen production in Penning-Malmberg traps.

Abstract
We present a pulsed "e+kick" scheme for removing ions from a positron plasma, along with other plasma routines used by the ASACUSA-Cusp Collaboration for making antihydrogen in 2023 and 2024. We also report on selected antimatter mixing experiments from 2023. Antiprotons are introduced into a plasma of 4×10^6 positrons with variable RF heating and mixing speed. The effects of these variables on antihydrogen yield are interpreted in a way that is consistent with theoretical predictions. Our observations provide general guidance for stable antihydrogen production in Penning-Malmberg traps.File in questo prodotto:
