A Damped Detuned Structure for the next Linear Collider
An X-band Damped Detuned Structure (DDS) for NLC has been fabricated as part of a collaboration between KEK and SLAC. The individual cells were diamond point machined and microwave tested at KEK. The cells were diffusion bonded at SLAC. The structure has been cold tested. The time dependence of the beam induced dipole wakefields have been measured with the SLC beam in the test station ASSET. Th...
متن کاملThe compact linear collider CLIC
A high luminosity 1034–1035 cm−2 s−1 electron–positron Collider (CLIC) with a nominal centre-of-mass energy of 3 TeV is being studied since a number of years at CERN within an international collaboration of laboratories and institutes to provide the HEP community with a new accelerator-based facility for the post-LHC era. In order to achieve the very high design luminosity, very low emittance b...
متن کاملBeam Tilt Signals as Emittance Diagnostic in the Next Linear Collider Main Linac
High frequency cavity beam position monitors (BPMs) can also provide information on the xz or yz correlation of the beam (yaw or pitch, respectively). Such a diagnostic is particularly desirable in the Next Linear Collider (NLC) main linacs, where the principal sources of emittance dilution generate such a correlation. Test results from the extremely low emittance beam at the KEK Accelerator Te...
متن کاملDevelopments in Beam-based Alignment and Steering of the next Linear Collider Main Linac
The Next Linear Collider main linacs are 13 km linear accelerators which each contain approximately 750 hybrid iron/permanent-magnet quadrupoles in a FODO array. The small amount of vertical emittance dilution permitted in the main linacs implies a tight tolerance on the RMS distance between the beam and the centers of the quads. We describe two methods for measuring the offsets between the qua...
متن کاملNew Post-Linac Collimation System for the Next Linear Collider
We present a new design for the NLC post-linac collimation system. The new design separates the collimation of off-energy particles and particles with large betatron amplitudes. The energy collimation system achieves passive protection against damage by an errant bunch train via large horizontal dispersion and vertical betatron functions, and makes use of optical symmetries to reduce jitter amp...
