Vacuum system for the LNLS 500-MeV booster synchrotron

Abstract: We present a summary of the commissioning and performance of the vacuum system of a 500-MeV booster synchrotron recently built at LNLS as part of a new injector for the LNLS light source. The main vacuum parameters of the synchrotron are pressure below 5x10 -7 Pa (lifetime of 1-2 hours), no in-situ baking, no cooling system, and a short recovery time after ventilation. All parts of the system are made of 1mm thick AISI 316L stainless steel. The chambers were pre-baked before installation.

We present results of the commissioning of a new injector for the Brazilian Synchrotron Light Source. The new injector consists of the existing 125-MeV LINAC and a new 500-MeV booster synchrotron. At present, about 40 mA can be injected into the booster and about 15 mA can be ramped up to 500 MeV at a repetition rate of 0.17 Hz. The new injector has allowed the accumulation of up to 540 mA in the main ring at 500 MeV and up to 305 mA has been ramped up to the storage ring nominal energy of 1.37 GeV. The new beam intensity is more than twice as large as the typical stored beam current before the installation of the booster synchrotron.
