Abstract
The intensity of the PS Booster is limited by space-charge defocusing forces which create a spread in the betatron tunes of up to ΔQ ≃ 0.5. Shaping of the transverse and longitudinal distributions was used for accommodating more particles in a given working area and enabled the Booster to accelerate 2 × 1013 protons per pulse, twice the design intensity. Modifying the RF potential well by an experimental second-harmonic cavity yields beam intensities and densities well beyond the present performance. The corresponding PSB experiments and improvements are described and an outlook on future developments is given.
