CLIC readiness report

E. Adli, G. D’Auria, Nuria Catalán Lasheras, Vera Cilento et autres

Abstract The Compact Linear Collider (CLIC) is a TeV-scale high-luminosity linear e + e − collider studied by the international CLIC and CLICdp collaborations hosted by CERN. CLIC uses a two-beam acceleration scheme, in which normal-conducting high-gradient 12 GHz accelerating structures are …

Injection and Extraction

F. Tecker

This paper gives an overview of the beam injection and extraction principles for accelerators. After a brief general introduction, it explains different methods of injecting the beam for hadron and lepton machines. It describes single- and multi-turn hadron injection, charge-exchange H- injection, …

Longitudinal Beam Dynamics in Circular Accelerators

F. Tecker

This paper gives an introduction of longitudinal beam dynamics for circular accelerators. After briefly discussing some types of circular accelerators, it focuses on particle motion in synchrotrons. It summarizes the equations of motion, discusses phase-space matching during beam transfer, and introduces the …

Advancing the CERN proton synchrotron multiturn extraction towards the high-intensity proton beams frontier

Alexander Huschauer, Hannes Bartosik, S. Cettour Cave, Marcel Coly et autres

Complementary to the physics research at the LHC, several fixed-target facilities receive beams from the LHC injector complex. To serve the fixed-target physics programme at the super proton synchrotron, high-intensity proton beams from the proton synchrotron are extracted using the multiturn extraction …

Beam-loading effect on breakdown rate in high-gradient accelerating cavities: An experiment at the Compact Linear Collider Test Facility at CERN

E. Senes, Theodoros Argyropoulos, F. Tecker, Walter Wuensch

Radio frequency breakdown rate is a crucial performance parameter that ensures that the design luminosity is achieved in the CLIC linear collider. The required low breakdown rate for CLIC, of the order of ${10}^{\ensuremath{-}7}\text{ }\text{ }\text{breakdown}\text{ }{\text{pulse}}^{\ensuremath{-}1}\text{ }{\mathrm{m}}^{\ensuremath{-}1}$, has been demonstrated in …
