Laser accelerators offer the promise of producing attosecond electron bunches from a compact accelerator. Electron source requirements for laser accelerators are challenging in several respects, but are achievable. We discuss these requirements, and propose an injector design. Simulation and design work for essential components for a laser accelerator electron source suitable for a high energy ...
A large dynamic aperture for a storage ring is of importance for long lifetimes and a high injection efficiency. Measurements of the dynamic aperture of the third generation synchrotron light source Advanced Light Source (ALS) using beam excitation with kicker magnets are presented. The experiments were done for various accelerator conditions, allowing us to investigate the influence of differe...
The control system based on the standard model of the UNIX and VMEbus system has successfully performed accelerator operation with 8GeV electron beams. The software architecture of the control system designed with the client/server scheme has well operated over the distributed computing environment with the FDDI opticalfiber network. The relational database system has been widely used for machi...
Electron-hadron colliders are the ultimate tool for high-precision quantum chromodynamics studies and provide microscope probing internal structure of hadrons. The electron is an ideal probe proton because it provides unmatched precision electromagnetic interaction, as virtual photon or vector bosons in a clean environment, kinematics which uniquely determined by beam scattered lepton, hadronic...
The SuperB international team continues to optimize the design of an electron-positron collider, which will allow the enhanced study of the origins of flavor physics. The project combines the best features of a linear collider (high singlecollision luminosity) and a storage-ring collider (high repetition rate), bringing together all accelerator physics aspects to make a very high luminosity of ...
The main design features of the PEP-II asymmetric two-ring electronpositron B Factory collider, built at the Stanford Linear Accelerator Center, are described. This facility will complete construction in June 1998. The high energy ring, completed in May 1997, has had 3 months of commissioning and successfully stored 0.75 A of electrons. The success of the high energy ring testing validates not ...
This paper reviews the status of existing and planned electron linacs. The progress on development of superconducting electron linacs is not discussed except for a few remarks on the SLAC conversion program study. Progress in the superconducting area is being reported in other papers 1,2,3 which are being presented to this conference. Because the SLAC accelerator is the largest existing electro...
We report the testing of a high gradient electron accelerator with a photonic-band-gap (PBG) structure. The photonic-band-gap structure confines a fundamental TM(01)-like accelerating mode, but does not support higher-order modes (HOM). The absence of HOM is a major advantage of the PBG accelerator, since it suppresses dangerous beam instabilities caused by wakefields. The PBG structure was des...
