Shaping of proton distribution for raising the space-charge of the CERN PS Booster

The intensity of the PS Booster is limited by space-charge defocusing forces which create a spread in the betatron tunes of up to Delta G approximately=0.5. Shaping of the transverse and longitudinal distributions was used for accommodating more particles in a given working area and enabled the Boos...

Descripción
Sumario:The intensity of the PS Booster is limited by space-charge defocusing forces which create a spread in the betatron tunes of up to Delta G approximately=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*10/sup 13/ 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. (14 refs).
