Mechanical and Vacuum Design of the Wiggler Section of the Ilc Damping Rings*
نویسندگان
چکیده
The design of the vacuum vessel for the wiggler sections of the ILC damping rings should meet a number of challenging specifications. Synchrotron radiation (SR) power of about 40 kW is generated in each wiggler. The expanding fan of SR reaches the beam vacuum chamber walls in the following wiggler and may cause the following problems: large power dissipation on vacuum chamber walls inside the cryogenic vessel; radiation damage of superconducting coils; high photo-electron production rate causing electron cloud to build up to an unacceptable level. Therefore, the power should be absorbed in places where these effects are tolerable or manageable. Some possible solutions for tackling all SR related problems as well as the vacuum design are discussed.

Sr Power Distribution along Wiggler Section of Ilc Dr*
A long wiggler section is required in each ILC damping ring to provide short radiation damping times. Synchrotron radiation (SR) generated by the beam in the wigglers must be absorbed by different components of the vacuum vessel, including specially designed absorbers. The optimisation of the mechanical design, vacuum system and electron cloud mitigation requires accurate calculation of the SR ...

متن کاملFast Ion Instability Simulations for CesrTA
In 2008, it has been proposed to convert the Cornell Electron Storage Ring (CESR) into a test accelerator, called CesrTA, for the proposed International Linear Collider (ILC) damping rings. One of the effects to be studied in CesrTA is fast ion instability. An electron beam ionizes residual gas in the vacuum chamber, resulting in positive ions being trapped in the beam’s potential. Fast ion ins...
متن کاملCoherent instabilities of ILC damping rings
1 Parameters The paper presents the first attempt to estimates the ILC damping ring impedance and compare thresholds of the classical instabilities for several designs initially proposed for the DR. The work was carried out in the spring of 2006. Since then the choice of the DR is narrowed. Nevertheless, the analysis described below may be useful for the next iterations of the beam stability. W...
