W-MAST (Wakasa-wan Energy Research Center Multipurpose Accelerator with Synchrotron and Tandem) consists of a tandem accelerator with 5MV terminal voltage and a compact ion synchrotron. The beam commissioning was started at the beginning of 1999 and was successfully accomplished in March 2000. A proton beam of 10MeV was injected from the tandem accelerator and accelerated by the ion synchrotron...

The Linac Coherent Light Source (LCLS) is a freeelectron laser (FEL) at SLAC producing coherent 1.5 Å x-rays. This requires precise, stable alignment of the electron and photon beams in the undulator. We describe construction and operational experience of the beam position monitor (BPM) system which allows the required alignment to be established and maintained. Each X-band cavity BPM employs a...

An Electron Beam Ion source Charge Breeder (EBISCB) has been developed to charge breed CARIBU radioactive beams at ATLAS and it is now in the final stages of off-line commissioning. Within the next year, the EBIS-CB will replace the existing ECR charge breeder to increase the intensity and improve the purity of reaccelerated radioactive ion beams. The integration of the new EBIS-CB requires: a....

We designed, constructed and have been operating a system based on single-crystal synthetic diamond sensors, to monitor the beam losses at interaction region of SuperKEKB asymmetric-energy electron-positron collider. The records radiation dose-rates in positions close inner detectors Belle II experiment, protects both detector accelerator components against destructive losses, by participating ...

The Linac Coherent Light Source (LCLS) is a SASE xray Free-Electron Laser (FEL) based on the final kilometer of the Stanford Linear Accelerator. Such an FEL requires a high energy, high brightness electron beam to drive the FEL instability to saturation. When fed by an RF-photocathode gun, and modified to include two bunch compressor chicanes, the SLAC linac will provide such a high quality bea...

At the creation of the CARE-HHH network in the year 2003 and during the six years of its existence the situation on beam instrumentation for HHH activities was: The LHC instrumentation was fully developed and was under construction or commissioning. The FAIR beam instrumentation encloses a large number of different instruments, but apart from the very high dynamic range in beam intensities no s...

In this report we will describe the muon collider target test beam line which operates off one branch of the AGS switchyard. The muon collider target test facility is designed to allow a prototype muon collider target system to be developed and studied. The beam requirements for the facility are ambitious but feasible. The system is designed to accept bunched beams of intensities up to 1.6x10 2...

Due to the presence of fringe ®eld on both magnet edges, the real trajectory traced out by the beam will deviate from expectation. The integral dipole strength seen by the beam will then have a discrepancy to design value. The beam tracing method is employed to correct fringe ®eld effect and to calibrate integral dipole strength of the bending magnets by tuning magnet current. Final correction ...

The Relativistic Heavy Ion Collider (RHIC) consists of two 3.8 km circumference rings utilizing 396 superconducting dipoles and 492 superconducting quadrupoles. Each ring will accelerate approximately 60 bunches of 10 protons to 250 GeV, or 10 fully stripped gold ions to 100 GeV/nucleon. Commissioning is scheduled for early 1999 with detectors for some of the 6 intersection regions scheduled fo...
