Commissioning and Operation of the First Brazilian Synchrotron Light Source

The synchrotron light source designed and constructed at the LNLS is composed of a 1.37 GeV electron storage ring and a 120 MeV linac for low-energy injection. The storage ring has been commissioned and has already reached the designed electron-beam energy, current and emittance. The electron lifetime is now 6 h at 60 mA, and is steadily increasing. Seven beamlines (TGM, SGM, SXS, XAFS, XRD, SAXS, PCr) have been constructed in parallel with the electron accelerators and are at present in operation. Beam time was allocated to 129 approved research projects for the second semester of 1997. A number of them are currently under way.

Commissioning and operation of the Brazilian Synchrotron Light Source

The Brazilian National Synchrotron Light Laboratory, LNLS, operates a 1.37 GeV electron storage ring with a 120 MeV injector linac. Commissioning of the storage ring at low energy started on May 1996 and now, an year later, we can store 120 mA at 120 MeV and ramp more than 75 mA to 1.37 GeV. A summary of the latest commissioning results and a description of the present operational performance of the LNLS Synchrotron Light Source facility is presented.

LNLS: the Brazilian synchrotron light laboratory

The authors present the status of the Laboratorio Nacional de Luz Sincrotron (LNLS) of Brazil as of January 1989 and discuss future plans for the installation. The 50-MeV linac will be assembled and commissioned during 1989. The full 100-MeV linac will be assembled and commissioned over the next two years. A major revision of the storage ring project has led LNLS to opt for a vacuum ultraviolet (VUV) ring as the circular machine to be built following the linac. It is due to be commissioned by 1992.<<ETX>>

LNLS status report

The Brazilian synchrotron light source consists of a 1.15 GeV electron storage ring with a 100 MeV injector. Most of their components have already been developed in‐house and production has started. The increase of injection energy is being considered via a booster, for full energy, or by recirculating the beam in the LINAC (200 MeV) [R. H. Farias et al. (unpublished)]. An update of the production and characterization of the accelerators components and beamlines is presented.

A progress report on the Laboratorio Nacional de Luz Sincrotron (Brazil) [Brazilian synchrotron light source]

We present a progress report on the design and construction of the Brazilian synchrotron light source facility, which is based on a 1.15 GeV (nominal energy) electron storage ring. To date, the first part of the linac injector (50 MeV) has been completed and is in operation. Prototypes for all the ring main components-magnets, vacuum chambers, kickers and septa, power supplies, control system, beam position monitors, RF cavity-have been developed in-house and characterized. An update of the production of these components, which is already under way, is presented. A report will be given later on the experience acquired with the laser cutting technique for the production of laminated magnets, pioneered by LNLS.<<ETX>>
