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 …

A compact low-level RF control system for advanced concept compact electron linear accelerator

Chao Liu, Larry Ruckman, Ryan Herbst, Bo Hong et autres

A compact low-level RF (LLRF) control system based on RF system-on-chip (RFSoC) technology has been designed for the Advanced Concept Compact Electron Linear-accelerator (ACCEL) program, which has challenging requirements in both RF performance and size, weight, and power consumption (SWaP). The compact …

FLASH: New intersection of physics, chemistry, biology, and cancer medicine

Marie‐Catherine Vozenin, Billy W. Loo, Sami Tantawi, Peter G. Maxim et autres

. These observations define the FLASH effect. The FLASH effect has been reported to occur when using single or hypofractionated dose regimens in several experimental animal models (mice, rat, zebrafish, pig, and cats) and in multiple organs (lung, skin, gut, and brain) …

A High-Flux Compact X-ray Free-Electron Laser for Next-Generation Chip Metrology Needs

J. B. Rosenzweig, G. Andonian, R. Agustsson, Petr M. Anisimov et autres

Recently, considerable work has been directed at the development of an ultracompact X-ray free-electron laser (UCXFEL) based on emerging techniques in high-field cryogenic acceleration, with attendant dramatic improvements in electron beam brightness and state-of-the-art concepts in beam dynamics, magnetic undulators, and X-ray …

Improving Cathode Testing with a High-Gradient Cryogenic Normal Conducting RF Photogun

Gerard Lawler, Fabio Bosco, Atsushi Fukasawa, Zenghai Li et autres

Future electron accelerator applications such as X-ray free electron lasers and colliders are dependent on significantly increasing beam brightness. With the observation that linac beam manipulation’s best preservation of max brightness is at the cathode, we are incentivized to create an environment …

High efficiency x-ray sources

Arundhuti Ganguly, Amy Shiroma, Filippos Toufexis, Sami Tantawi

We have developed high efficiency, variable-energy x-ray sources based on distributed coupling linacs. These linear accelerators have >2x beam-to-RF efficiency compared to conventional linacs. Separate feeds for cavities allow for their individual optimization for maximum output instead of feeding the RF power …
