Orbit Correction in the Lnls Uvx Electron Storage Ring
نویسندگان
چکیده
The orbit measurement and correction system of the LNLS synchrotron light source is presented. Recent changes to the system including the addition of 12 vertical correctors and the use of 16 bit DACs to control the corrector magnet power supplies have improved the vertical orbit repeatability from fill to fill from ±70 μm to ±3 μm. The improved resolution also allowed the implementation of automatic orbit corrections at 24 second intervals, thus reducing orbit variations along a user’s shift from ±70 μm to ±5 μm.

Commissioning of the Lnls X-ray Bpms
We present experimental results of the commissioning of staggered-pair blade X-Ray beam position monitor (XBPM) recently developed and installed at the diagnostic beamline of the UVX electron storage ring at the Brazilian Synchrotron Light Laboratory (LNLS). The results obtained with a prototype XBPM indicate that the short-term and long-term data are both in agreement with the data from a comm...
متن کاملMagnet Alignment Method, Alignment Results and Closed Orbit Distortion for the SPring-8 Storage Ring
Abstract Third generation synchrotron radiation sources have high sensitivity against errors and large closed orbit distortion is generated resultantly. We found the alignment method to reduce the effective sensitivity and applied it to the SPring-8 storage ring. We succeeded to reduce the effective sensitivity substantially. Observed closed orbit distortions without correction were 1.4 mm for ...
متن کاملOrbit Stabilization in Spring-8 Storage Ring
Stability of electron orbit is one of the most important properties to achieve brilliant photon beams for third generation synchrotron radiation sources. In the design of a SPring-8 storage ring, many ideas for orbit stabilization were thus considered. Consequently, without any correction, electron orbit stability of about 50 μm per day is obtained. Since a main part of the orbit movement is sl...
متن کاملThe Lnls Booster Synchrotron Dipole Magnets
* [email protected] Abstract 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 cu...
متن کاملObservation of CHG Spectrum at UVSOR-II
At synchrotron light sources, the drift of the orbit of the electrons in the storage ring causes a drift of the light source position, which affects user’s experiments. At UVSOR-II, an RF feedback system [1] has been operating to suppress the orbit drift on the horizontal plane caused by the thermal expansion of the storage ring floor. However, on the vertical plane, there’s no system to stabil...
