We integrated an injector linac control system to the SPring-8 standard system in September 2000. As a result of this integration, the SPring-8 accelerator complex was controlled by one unified system. Because the linac was continuously running as the electron beam injector not only for the SPring-8 storage ring but also for NewSUBARU, we had to minimize the hardware modification to reduce the ...

The production of ultra-short x-rays in Cornell’s Energy Recovery Linac (ERL) requires electron bunch lengths of less than 100fs with minimal transverse emittance growth and energy spread. Because the linac consists of two sections separated by an arc, CSR forces limit the bunch length in the linac, and bunch compression has to be done after acceleration. Creation of such short bunches requires...

Accurate measurement of quadrupole-to-BPM center offsets and use of this information in an autosteering algorithm are two essential components of emittance preservation in the Next Linear Collider main linac. We present the results of an analytic/simulation study of possible statistical and systematic limitations on the measurement of quad-BPM center offsets. These results are incorporated in a...

A high power proton accelerator project, Proton Engineering Frontier Project (PEFP), as one of the 21C Frontier Projects promoted by Korean Government, has the goals to develop a 100 MeV high current proton linear accelerator and the user programs for its beam utilization and industrial applications. The upstream part of the 100 MeV linac, the 20 MeV linac, was successfully developed and tested...

The PLS (Pohang Light Source) linac has been operated routinely as the injection linac for PLS, a thirdgeneration synchrotron light source. The transverse electron beam emittance was measured at the preinjector end of the PLS linac, where the beam energy is about 100 MeV. The emittance was measured using a quadrupole magnet and a fluorescent target. We used a progressive scan CCD camera with an...

A sampled phase-locked loop synchronizes the PEP-II B Factory rings to their SLAC Linac injector. The injection of both electrons and positrons into the separate rings and into their proper RF buckets requires phase shifting the linac RF with respect to the PEP rings. One of every three machine cycles provides the PEP ring an undisturbed reference while the other two thirds of the time the refe...

We describe the design of a proposed source of ultra-fast synchrotron radiation x-ray pulses based on a recirculating superconducting linac, with an integrated array of ultrafast laser systems. The source produces x-ray pulses with duration of 10-50 fs at a 10 kHz repetition rate, with tunability from EUV to hard x-ray regimes, and optimized for the study of ultra-fast dynamics. A high-brightne...

TRIUMF is funded through to 2005 to proceed with an extension to the ISAC facility, ISAC-II, to permit acceleration of radioactive ion beams up to energies of at least 6.5 MeV/u for masses up to 150. The upgrade includes the addition of a post-stripper superconducting linac to accelerate beams of 3 ≤ A/q ≤ 7 to an energy of at least 6.5 MeV/u. The possibility of using the superconducting linac ...

Different types the spectrum of photons were studied; they were emitted from the flattening filter of a LINAC Varian 2100 C/D that operates at 15 MV. The simplified geometry of the LINAC head was calculated using the MCNPX code based on the studies of the materials of the flattening filter, namely, SST, W, Pb, Fe, Ta, Al, and Cu. These materials were replaced in the flattening filter to calcula...
