The push to create a high luminosity Higgs factory requires the generation and preservation of low emittance beams. In this new low emittance regime, collective effects previously considered negligible must be re-examined, such as intrabeam scattering, which leads to the increase of the sliced energy spread. Omitting intrabeam scattering in our simulations may result in unrealistically high...

The Cool Copper Collider (C3) is a proposed electron-positron linear-collider Higgs factory which leverages the high accelerating gradient achieved when a normal conducting copper cavity is cryogenically cooled with liquid nitrogen. To produce suitably short, flat, low emittance electron and positron beams, prior to the main Linac, a damping ring and bunch compressor are employed. In this...

Laser-driven Compton backscattering (CBS) has been proposed as method for controlling the intensity of colliding bunches in the FCC-ee so as to avoid the flip-flop instability. Laser-based collimation has also been proposed as an indestructible collimator for high-intensity electron beams, which could significantly reduce the length of a Linear Collider Beam Delivery System. We have initiated...

The KEK ATF (Accelerator Test Facility) serves as a dedicated testbed for developing beam instrumentation technologies in support of the International Linear Collider (ILC) project. As such, it incorporates a variety of diagnostic tools based on laser systems and photodetection technologies. At the ATF, nanometer-scale beam (nanobeam) technology development is underway using the Final Focus...

In the framework of developing a high-resolution cavity beam position monitor (cBPM) and data acquisition (DAQ) system for future linear colliders, a re-entrant cBPM designed at CEA Saclay [1] was tested at the end of the LINAC at the Accelerator Test Facility (ATF), KEK. Position and reference signals are extracted from the same BPM and processed identically. The signals at 1.725 GHz (dipole...

The Accelerator Test Facility (ATF) at KEK serves as a prototype for the Final Focus Systems envisioned for future electron–positron linear colliders, including the International Linear Collider (ILC) and the Compact Linear Collider (CLIC). To enable both advanced RF-Track simulations and corrections of unwanted effects with a unified approach, a Python-based “Flight Simulator” was developed...

The International Linear Collider (ILC) is a proposed electron–positron collider envisioned for the post-LHC era. Its Beam Delivery System (BDS) transports the beam from the main linac and focuses it to nanometer-scale dimensions at the Interaction Point (IP). Along this path, the beam passes through collimators, diagnostic instruments, and strong magnetic elements. Intensity-dependent effects...

A new Beam Delivery System (BDS) has been developed for the 1.5 TeV stage of the Compact Linear Collider (CLIC). While the original 3 TeV BDS design was previously considered adequate for operation at 1.5 TeV, the revised design takes advantage of the reduced synchrotron radiation (SR) at lower energy. The reduced SR permits the use of stronger bending dipoles and consequently weaker...

As interest in advanced acceleration techniques for future high-energy colliders continues to grow, there is increasing demand for Beam Delivery Systems (BDS) capable of transporting beams with energies beyond the CLIC design. While plasma-based collider concepts offer the potential for significantly reduced accelerator footprints, the BDS is expected to dominate the overall facility length at...

This work presents a first design study of the Beam Delivery System (BDS) for the Hybrid Asymmetric Linear Higgs Factory (HALHF); a novel electron-positron collider concept based on a combination of RF- and plasma-accelerator technology, targeting precision Higgs physics. Due to the highly asymmetric nature of the electron and positron bunches, HALHF operates with significantly larger...

EuPRAXIA@SPARC_LAB will be the first European research infrastructure designed to demonstrate plasma-based acceleration, combining a high-brightness GeV-class electron beam with a state-of-the-art X-band linac and a 0.5 PW-class laser system. The success of this facility critically depends on the preservation of beam quality during acceleration, as wakefields and structural misalignments in...
