Description
Antiprotons are generated at CERN by extracting a high-intensity proton beam
from the Proton Synchrotron (PS) onto a target. The resulting antiprotons are
captured in the Antiproton Decelerator (AD) ring. As the AD is about three
times shorter than the PS, the entire primary proton beam must be compressed
to less than one third of the PS circumference. The previous batch compression
brought four bunches injected from the PS Booster (PSB) into consecutive RF
buckets at a harmonic number of 20. An improved injection and compression
scheme has been developed and commissioned to deliver five bunches to the
AD. It became feasible thanks to the upgrades of the injector complex for the
High-Luminosity LHC (HL-LHC). One of the four PSB rings delivers twice
higher intensity in two bunches, and an optimized sequence of nine different RF
harmonics has been set up to obtain five bunches within one quarter of the PS
circumference. The contribution summarizes the main changes to the antiproton
production beam, as well as the experience of the first year of operation. Results
of beam tests with increased total intensity are presented.
