Updated Design of the Italian Superb Factory Injection System
نویسندگان
چکیده
The ultra high luminosity B-factory (SuperB) project of INFN [1, 2] requires a high performance and reliable injection system, providing electrons at 4 GeV and positrons at 7 GeV, to fulfill the very tight requirements of the collider. Due to the short beam lifetime, continuous injection of electrons and positrons in both High Energy Ring (HER) and Low Energy Ring (LER) is necessary to keep the average luminosity at a high level. An updated version of the injection system, optimized at higher repetition frequency is presented. This scheme includes a polarized electron gun, a positron production scheme with electron/positron conversion at low energy 0.6 GeV, and a 1 GeV damping ring to reduce the injected emittance of the positron beam.

TOUSCHEK BACKGROUND AND LIFETIME STUDIES FOR THE SuperB FACTORY
The novel crab waist collision scheme under test at the DAΦNE Frascati Φ-factory finds its natural application to the SuperB project, the asymmetric ee flavour factory at very high luminosity with relatively low beam currents and reduced backgrounds. The SuperB accelerator design requires a careful choice of beam parameters to reach a good trade-off between different effects. We present here si...
متن کاملFactory Developments
The impressive performance of current (KEKB) and recent (PEP-II) B-Factory colliders has increased interest in developing even higher luminosity B-factories. Two new designs are being developed (SuperKEKB and SuperB). Both designs plan to deliver a luminosity in the range of 1×10 cms, nearly 100 times the present B-factory level. Achieving this high luminosity requires high-current beams and sh...
متن کاملThe Superb Accelerator: Overview and Lattice Studies
SuperB [1] aims at the construction of a very high luminosity (10 cm s) asymmetric ee Flavour Factory, with possible location at the campus of the University of Rome Tor Vergata, near the INFN Frascati National Laboratory. In this paper the basic principles of the design and details on the lattice are given.
متن کاملSuperb Bunch - by - Bunch Feedback R & D *
The SuperB project has the goal to build in Italy, in the Frascati or Tor Vergata area, an asymmetric e+/eSuper Flavor Factory to achieve a peak luminosity > 10**36 cm-2 s-1. The SuperB design is based on collisions with extremely low vertical emittance beams and high beam currents. A source of emittance growth comes from the bunch by bunch feedback systems producing high power correction signa...
متن کاملApplying whole system design in a sportscar factory
Basing on a paper which explores the adoption of a whole system approach to a more sustainable and innovative design, the present paper wants to apply the same approach to a real case, inside of a famous Italian sportscar factory. A case study in this factory was developed and decodified gaining improved understanding of whole system design and those factors that substantially influence its suc...
