ILC main linac alignment simulations using conventional techniques and the rapid tunnel reference survey model (RTRSM)

Abstract:

Alignment of the ILC main linac will be more critical than for any currently existing accelerators due to its long length and the ultra low emittance required. There are several techniques for measuring the ILC reference network; in this report conventional methods for measuring the network and aligning the main linac are simulated. Dispersion Matched Steering (DMS) is applied to the simulated accelerators to determine their final emittance. Simulations and reconstructions of the ILC reference network usually require very resource intensive programs, the RTRSM has been developed to rapidly generate networks with the required statistical properties. The RTRSM is discussed in this report and some problems are demonstrated.

First data from the linear collider alignment and survey project (LiCAS)

Proceedings of EPAC08 European Physical Society (2008) 1344-1346

Authors:

Armin Reichold, Patrick Brockill, Sigal Cohen, John Dale, Mike Dawson, Tony Handford, Mark Jones, Gregory Moss, Lee Rainbow, Michael Tacon, Cecilia Uribe Estrada, David Urner, Roy Wastie, Stephanie Yang

Abstract:

The LiCAS project has developed a prototype robotic survey system for rapid and highly accurate surveying of long linear accelerator tunnel networks. It is aimed at the International Linear Collider (ILC). This Rapid Tunnel Reference Surveyor (RTRS) is an R&D; instrument for evaluating the performance of the RTRS concept and its survey technology. The prototype has been commissioned in a test tunnel at DESY with initial calibrations and measurements ongoing. We will report recent results where they improve over previously reported work.

Nanometre precision interferometric stability monitoring systems for key accelerator components

Abstract:

The MONALISA group develops novel, accurate, nanometre resolution, interferometric systems to monitor relative motions between key accelerator components. We use cost-effective technology developed for the telecommunications market, providing readily scalable, adaptable solutions. Key magnets and diagnostics in the beam-delivery section of the International Linear Collider (ILC) will need to maintain stable relative positions. In particular, the final focus quadrupole magnets require nanometre level stability. Even greater stability requirements will be placed on components for the Compact Linear Accelerator (CLIC). Interferometers provide the only means of monitoring relative positions over long timescales, at the nanometre and sub-nanometre level. The latest results from our novel design, fibre-coupled interferometers will be presented.
