A preliminary design for the main Linac for the 250 GeV center-of-mass energy version of the Cold Copper Collider (C3) is presented. This design was used to understand the beam dynamics for the C3 accelerator and specify expected alignment and vibration tolerances.
The Compact Linear Collider (CLIC) is a proposed linear accelerator designed to collide electrons and positrons at energies up to 3 TeV. In order to explore new physics and to be more competitive with other collider projects, CLIC is exploring the increase of the center-of-mass energy to 7 TeV. The CLIC Beam Delivery System (BDS) transports the lepton beams from the exit of the Main Linac to...
High luminosity electron-positron linear colliders constitute a fundamental instrument in the field of elementary particle physics. The ``Cool copper collider", or C$^3$, is a proposal for a 250 COM GeV Higgs factory, with possible extension to the TeV-scale, and it represents a promising candidate for the near future high energy physics. The C$^3$ infrastructure is conceived as a modular...
The previous designs of the CLIC RTML BC2 RF accelerating structures are found to be either not optimal in terms of consumption powers and costs, or problematic in the structure performance test or in the BBA test. Threfore, we optimised the structures for a minimum cost and a successful BBA test, based on an existing X-band structure design that was designed for the CLIC klystron-based main...
The scientific mission of the International Linear Collider (ILC) relies on achieving high-energy high-luminosity beam collisions, which necessitate a low emittance beam transport section to ensure the maintenance of high-quality beam along the accelerator. Thus, the preservation of beam emittance during acceleration represents a fundamental design and operational objective of the ILC...
ILC technology network (ITN) is currently being promoted to facilitate the development of ILC-related technologies for the engineering design of ILC. ITN contribution of KEK in the areas of DR and BDS will be presented.
Beam parameter optimization is the most important topic in beam operation.
I will present the automatic beam tuning and the tuning technique for better optimization using machine learning at ATF/ATF2.
The emittances of the injected and extracted beams, the structure of the bunch train, and the repetition rate are critical parameters of the damping ring, which indirectly determine the luminosity of future colliders. Injection and extraction systems are one of the main components of damping rings. A pulse kicker in tandem with a DC septum magnet controls the bunch orbit in these systems. The...
The CLIC Beam Delivery System (BDS) transports the lepton beams from the exit of the Main Linac to the Interaction Point (IP). The Final Focus System (FFS) is the last part of the BDS and its role is to focus the beam to the required size at the IP and to cancel the chromaticity of the Final Doublet (FD). MAD-X and MAD-NG are simulation codes for beam dynamics and optics that are used for...
The beam loading (BL) effect results in the reduction of the gradient due to the interaction of the beam with the accelerating cavity. This phenomenon leads to energy losses for long trains of particles. Such an energy degradation is non-negligible in compact and high-intensity linear accelerators, whose popularity is increasing due to their industrial and medical potential. To account for...
The two-beam accelerator is one of two primary concepts for the structure wakefield acceleration approach to an e+e- collider. Transient beam loading effects are a significant challenge for the drive beam in a TBA structure, where energy droop in ~50 nC electron bunch trains must be understood and compensated. This problem is being studied at the Argonne Wakefield Accelerator (AWA), where the...
The start-to-end beam dynamics simulation plays an important role in
accelerator design performance optimization.
A parallel beam dynamics framework, IMPACT code suite, has been used
in start-to-end beam dynamics optimization of linear accelerator
design of an x-ray FEL light source. In this talk, we will present
the physical and numerical models in this framework, show an...
Cool Copper Collider (C3) offers a unique opportunity to study the Higgs physics. A C3 Demonstration R&D Plan, or the C3 Demonstrator (C3Demo), is an on-going effort to address the R&D and answer the technical questions in a staged approach, ending with a multi-cryomodule linac of 2 GeV electron beams. We report simulation on C3Demo beam dynamics with injector, acceleration, and compression....
