Synergia Simulations of Injecting Painting Support PIPII Scientific

Synergia Simulations of Injecting Painting Support PIP-II Scientific Achievement Synergia simulation of injection painting of the PIP-II superconducting linac into the Booster shows flat charge density for reduced space charge forces and contributed to a successful CD-2/3 a review Significance and Impact To achieve the goals of the PIP-II upgrade, we need to paint the phase space of the beam injected into the Booster to spread the charge density and reduce space charge. Research Details – The PIP-II project will build an 800 Me. V superconducting linac to inject into the Booster. – 285 linac bunchlets are injected into Booster. Each injection occurs at a different transverse position. – Between injections, normal phase rotation occurs to mix up the distribution. – The Synergia simulation programmatically mimics what would occur during operation of accelerator. x - px y – py Particle phase space: The x-px (left) and y-py (right) phase space distributions after 150 out of 285 injections. The x-px phase space is injected starting from the outside so the hole in the center is visible as is the braided outlines of multiple bunchlets. The y-py phase space is injected starting from the inside so it is smooth to the center. Work was performed at Fermi National Accelerator Laboratory
