5. Probing non-perturbative QED and new physics in laser-particle beam collisions at LUXE and prospects for a future Higgs factory

Applications

Oral presentation (in person)

The proposed LUXE experiment (Laser Und XFEL Experiment) at DESY, Hamburg, using the 16.5 GeV electron beam extracted from the European XFEL, aims to study collisions between high-intensity laser pulses and high-energy electron or secondary photon beams (unique feature at LUXE). This will elucidate quantum electrodynamics (QED) at the strong-field frontier, where the electromagnetic field of...

105. The alignment of the modules of the Cool Copper Collider (C^3) with the Rasnik 3-point alignment system

Applications

Oral presentation (remote)

For C^3, approximately 2000 accelerator sub units must be positioned, within 10 um transversal, on a 2.3 km long straight line for each linac.
In the Rasnik alignment system, light from a point-like monochromatic source falls on a zone plate, forming a Fraunhofer diffraction pattern on an image pixel sensor. The alignment of three objects can be obtained by analyzing the position of the...

226. Compact Traveling Wave X-band Linac with RF Power Flow Outside Accelerating Cavities

Valery Dolgashev (SLAC National Accelerator Laboratory)

10/07/2024, 15:00

Applications

Oral presentation (in person)

During the development of the NLC/JLC normal conducting X-band linear colliders, it became clear that the RF power flow in traveling wave accelerating structures correlates more with the RF breakdown rate than with the peak electric fields. To mitigate the adverse effects of RF power flow, low group velocity and standing wave accelerating structures optimized for lower RF input power have been...

241. High-Gradient X-band Linac for Direct Electron Radiation Therapy

Emma Snively (SLAC National Accelerator Laboratory)

Applications

Oral presentation (remote)

We report on cold test measurements of an X-band (11.424 GHz) accelerator to provide electron beams for Very High Energy Electron therapy of cancer. The standing wave linac is designed with a 135° phase advance utilizing distributed coupling through four parallel manifolds. The accelerator is expected to reach a 100 MeV/m accelerating gradient in a one-meter structure using only 19 MW when...

189. Modeling and Design of the SLAC 75XP4 Klystron

Brandon Weatherford

Applications

Oral presentation (in person)

The SLAC 75XP series klystron was developed in the late nineties / early 2000’s as a 60% efficient, 75 MW permanent magnet-focused klystron at X-band for the Next Linear Collider (NLC). SLAC is pursuing the latest design iteration of the 75XP series – the 75XP4 - for potential deployment in future colliders facilities like Cool Copper Collider. Here, we discuss the history and lessons learned...
