Status of the CLIC/CTF Beam Instrumentation R&D

The Compact Linear Collider (CLIC) is an e⁺/e⁻ collider based on the two-beam acceleration principle, proposed to support precision high-energy physics experiments in the energy range 0.5-3 TeV. To achieve a high luminosity of up to 6e34cm⁻²s^{−1}, the transport and preservation of a low emittance beam is mandatory. A large number and great variety of beam diagnostics instruments is foreseen to verify and guarantee the required beam quality. We present the status of the beam diagnostics developments and experimental results accomplished at the CLIC Test Facility (CTF), including new ideas for simplification and cost reduction of the CLIC beam instrumentation.
