A CORBA Based Client-Server Model for Beam Dynamics Applications at the SLS

ICALEPCS 99, 4-8 Oct. 1999, Trieste, Italy, 1-SEP-1999, 3 pages [PS] [PDF]

A distributed object oriented client-server model, based on the Common Object Request Broker Architecture (CORBA), has been established to interface beam dynamics application programs at the Swiss Light Source (SLS) to essential software packages. These include the accelerator physics package, TRACY, the Common DEVice (CDEV) control library, a relational database management system and a logging facility for error messages and alarm reports. The software architecture allows for remote clients to invoke computer intensive methods, such as beam orbit correction procedures, on a dedicated server running the UNIX derivative, Linux. Client programs typically make use of graphical user interface (GUI) elements provided by specialized toolkits such as Tk or Java Swing, while monitored data required by procedures utilising the TRACY library, such as beam optics parameters, are marshalled to the model server for fast analysis. Access to the SLS accelerator devices is achieved through a generic C++ CDEV server...

Possible Upgrading of the SLS RF System for improving the Beam Lifetime

PAC-99, New York, March 1999, 1-JAN-1999, 3 pages [PS] [PDF] [DOC]

The RF system which was adopted for the SLS (Swiss Light Source) initial phase is based on the choice of conventional, already well-proven equipment. The use of superconducting (sc) cavities has been ruled out as a starting solution. However, for improving the beam lifetime in the storage ring (SR) when operating at very high brightness, the initial normal conducting (nc) system could be further complemented with idle (only-beamdriven) sc cavities. Within that scheme, two different approaches have been investigated: either doubling the fundamental RF voltage using one 500 MHz sc cavity, or lengthening the bunches with one (possibly two) third harmonic sc cavity(ies). These upgrading options are discussed here.

RF System for the SLS Booster and Storage Ring

PAC-99, New York, March 1999, 1-MAR-1999, 3 pages [PS] [PDF] [DOC]

The RF system which was adopted for the SLS (Swiss Light Source) initial phase is based on the use of conventional, already well-proven equipment. In the storage ring (SR), it consists of four 500 MHz plants, each comprising a normal conducting (nc) single-cell cavity of the ELETTRA type, powered with a 180 kW CW klystron amplifier via a WR1800 waveguide line. In spite of the lower power requirement, one similar plant will be used for the booster with the intention of standardizing. Although the use of superconducting (sc) cavities has been ruled out as a starting solution, combining idle (no external RF source) sc cavities with the initial nc system is regarded as a possible way of further improving the beam lifetime in the SR when operating at very high brightness.

Beam Lifetime studies for the SLS storage ring

PAC-99, New York, March 1999, 1-MAR-1999, 3 pages [PS] [PDF] [HTML]

SLS is a high brightness light source with 4.8 nm emittance at 2.4 GeV. Particle losses due to Touschek scattering will strongly affect the beam lifetime. We present Touschek lifetime calculations based on a refined tracking procedure for determination of the lattice momentum acceptance. The dependency of lifetime on the gap height of insertion devices and on the RF cavity voltage is studied in detail for the reference optics of the SLS storage ring lattice. Including gas scattering losses we expect 3.5 hrs of total lifetime for 1 nCb bunch charge and 0.1 % coupling. Installation of a 3rd harmonic cavity for bunch lengthening would increase the total lifetime to 8 hrs and thus is recommended.

Studies on Imperfections in the SLS storage ring

PAC-99, New York, March 1999, 1-MAR-1999, 0 pages [PS] [PDF] [HTML]

Studies on linear and nonlinear imperfections in the SLS storage ring operated at 2.4 GeV are presented. The in- fluence of spurious vertical dispersion and linear coupling on the vertical emittance and possible correction schemes are discussed. The deterioration of the Dynamic Aperture caused by higher order multipoles is investigated based on field calculations. Furthermore the influence of ground waves on the orbit stability is estimated.

Fast Closed Orbit Control in the SLS storage ring

PAC-99, New York, March 99, 1-MAR-1999, 3 pages [PS] [PDF] [HTML]

Concepts for a fast orbit feedback in the SLS storage ring are presented. The Singular Value Decomposition (SVD) based orbit correction scheme is supposed to fight orbit oscillations up to 100 Hz stabilizing the orbit to 1/10th of the beam sigma at the locations of the insertion devices. For an emittance ratio of 1%, this corresponds to 1 micron tolerance in the vertical plane. In order to achieve this high accuracy strong restrictions are imposed on the residual noise of the beam position monitoring and the correction system. Theoretical estimates for the feedback gain are made using a simplified feedback model. The proposed layout of the feedback electronics based on the SLS digital BPM system is also described.
