“…The major milestone in injector improvements took place in 2001, when a booster synchrotron [3] was installed allowing the injection energy to be upgraded from 120 MeV (the energy of the beam from the injector LINAC) to 500 MeV. Figure 1 shows the present configuration of the injector system.…”

We present the results of hardware, software and operational improvements implemented at the injector complex of the 1.37 GeV electron storage ring of the Brazilian Synchrotron Light Source (LNLS) with the aim of improving injector stability and reliability, thus reducing the injection time. The improvements include changes to the 120 MeV injector LINAC RF system and high power modulators, injection automation and the implementation of a new procedure for reusing the current at the end of each user´s shifts before injection by ramping the energy back down to 500 MeV (the injection energy) without dumping the beam. All of these changes allowed us to significantly reduce the overall time from the end of a shift to the delivery of beam in the following shift with a positive impact on the reduction of injection thermal transients for the storage ring and beamlines. Further improvements are expected in the near future as a result of planned changes to the injection timing system and of the installation of a recently assembled upgrade of the 500 MeV booster synchrotron RF system.

“…The consequences for the beam optics arise in strong fringe field effects which cannot be neglected. The main injector parameters are described in reference [1]. In this report, we concentrate on experimental results on the booster magnet design and characterization as well as its impact on the magnetic lattice design.…”

The Brazilian Synchrotron Light Laboratory (LNLS) has just constructed and commissioned a 500 MeV booster synchrotron to be used as injector for the 1.37 GeV electron storage ring. The booster has been constructed inside the storage ring, where the constraints in space are very tight. For this reason, the booster dipoles were made as small as possible, i.e., with small curvature radius (magnetic field of 1.6 T) and appreciable fringe field effects. In this report we present the results for the characterization of these magnets and simulation of their effects on the booster optics.

We describe the theory of operation and the results obtained with the upgrade of the timing system of the LNLS Synchrotron Light Source, developed as a result of the construction of a new 500-MeV booster synchrotron. The system uses ECL logic and differential transmission of the signals through the backplane, which is connected to 11 delay modules that produce the trigger signals necessary for all pulsed hardware in the accelerator facility, including klystron modulators, electron gun, kickers and septa. All trigger signals are synchronized with the coincidence signal of booster and storage ring revolution frequencies. The rms jitter between two delay modules is 200 ps, whereas the rms jitter with respect to the RF waveform is below 20 ps.
