SEARCHES FOR NEW PARTICLES AT PEP. Open
The status of searches for new particles at the PEP storage ring is reviewed. The result of the excited electron search by MARKII is presented and a limit on the coupling strength of the e*e..gamma.. vertex is given. The search for single …

Availability Studies Comparing Drive Beam and Klystron Options for the Compact Linear Collider Open
The initial proposal for the Compact Linear Collider (CLIC) is based on a two beam-scheme to accelerate the main colliding beams. For low collision energies, the main beam could also be accelerated by powering the accelerating structures w…

Availability Allocation to Particle Accelerators Subsystems by Complexity Criteria Open
In the early design stages of an accelerator, an effective allocation method is needed to translate an overall accelerator availability goal into availability requirements for its subsystems. During the allocation process, many factors are…

Beam Related Machine Protection of the Future Circular Collider Open
In the Future Circular Collider (FCC) study, each nominal proton beam at top particle energy of 50 TeV has an energy of 8500 MJ, which is more than 20 times the energy of today's Large Hadron Collider (LHC) beam. Machine protection of such…

Methodology Applied for Dependability Studies on the Compact Linear Collider Open
The Compact Linear Collider (CLIC) scheme presents several challenges in terms of reliability and availability. The goal of the study is to demonstrate the requirements for availability and reliability by identifying the key factors on fai…

Dependability Studies for CERN PS Booster RF System Upgrade Open
Radio frequency systems are a vital part of almost all accelerators. The request for a higher beam bright-ness from the injector chain of CERN's Large Hardon Collider, as demanded by the future High-Luminosity program, has motivated, among…

DESIGN PROCESS OF THE INTERLOCK SYSTEM FOR THE COMPACT LINEAR COLLIDER Open
The Interlock system forms a critical part for the ma-chine protection of linear colliders. Its goal is to inhibit the next pulse either on failure of critical equipment and/or on bad beam quality evaluation. This paper presents the on-goi…
