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, now supplies a bunch of electron -cooled antiprotons at a fixed energy of 100 keV. The MUSASHI antiproton trap was upgraded by replacing the radio -frequency quadrupole decelerator with a pulsed drift tube to re -accelerate antiprotons and optimize the injection energy into the degrader foils. By increasing the beam energy to 119 keV, a cooled antiproton accumulation efficiency of (26 +/- 6) % was achieved.

Abstract
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, now supplies a bunch of electron -cooled antiprotons at a fixed energy of 100 keV. The MUSASHI antiproton trap was upgraded by replacing the radio -frequency quadrupole decelerator with a pulsed drift tube to re -accelerate antiprotons and optimize the injection energy into the degrader foils. By increasing the beam energy to 119 keV, a cooled antiproton accumulation efficiency of (26 +/- 6) % was achieved.File in questo prodotto:
