Rcds Optimizations for the Esrf Storage Ring
نویسنده
چکیده
The Robust Conjugate Direction Search (RCDS) [1] optimizer is applied for online optimizations of the ESRF accelerators. This paper presents the successful application of the algorithm in reducing vertical emittance, improving injection efficiency and increasing lifetime. A new set of sextupole settings to increase chromaticity has been obtained with lifetimes comparable to the existing one. This allows to run with double current in a single bunch, and unifies the optics for few bunch (except 4×10 bunches) and multi-bunch modes.

Measurements of radiation levels inside the ESRF storage ring
Radiation damage observed on a number of cables in the storage ring has triggered a series of radiation measurements inside the storage ring to assess dose levels during injection and during stored beam conditions. Photon dose rates have been measured in different locations, using small ionization chambers. The results show a strong spatial variation of the measured dose rates and indicate that...
متن کاملExperimental Frequency Maps for the Esrf Storage Ring
Experimental frequency maps have already revealed unknown characteristics of the ESRF storage ring non-linear dynamics. In the past year, several efforts were undertaken in order to establish this technique as an operational online tool. The acquisition time was significantly reduced by collecting data from a dedicated fast BPM system. The problem of beam decoherence was limited by establishing...
متن کاملVertical Emittance Reduction and Preservation at the Esrf Electron Storage Ring
In 2010 a campaign for the reduction and preservation of low vertical emittance at the ESRF electron storage ring was undertaken: values between 20 and 30 pm have been dramatically reduced to 3.5 pm, even during beam delivery. This improvement is the result of an increased measurement precision provided by the recently upgraded beam position monitoring system, a new correction algorithm, a larg...
