Update in the optics design of monochromatization interaction region for direct Higgs s-channel production at FCC-ee
/ Zhang, Zhandong (Beijing, Inst. High Energy Phys. ; IJCLab, Orsay ; Beijing, GUCAS) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; Jiang, Hongping (Unlisted, CN) ; Bai, Bowen (Harbin Inst. Tech.) ; Raimondi, Pantaleo (Fermilab) ; Zimmermann, Frank (CERN) ; Oide, Katsunobu (U. Geneva (main) ; KEK, Tsukuba)
The FCC-ee could allow the measurement of the electron Yukawa coupling via direct Higgs s-channel production at ~125 GeV centre-of-mass (CM) energy, provided that the CM energy spread of this channel, can be reduced to about 5–10 MeV to be comparable to the width of the standard model Higgs boson. The natural collision-energy spread at 125 GeV, due only to synchrotron radiation (SR), is about 50 MeV. [...]

Monochromatization Interaction Region Optics Design for Direct s-channel production at FCC-ee
/ Zhang, Z D (Beijing, Inst. High Energy Phys. ; BSRF, Beijing ; IJCLab, Orsay) ; Faus-Golfe, A (IJCLab, Orsay) ; Jiang, H P (Harbin Inst. Tech.) ; Bai, B W (Harbin Inst. Tech.) ; Zimmermann, F (CERN) ; Oide, K (Sokendai, Tsukuba ; KEK, Tsukuba ; Geneva U.)
One of the most fundamental measurements since the Higgs boson discovery, is its Yukawa couplings. Such a measurement is only feasible, if the centre-of-mass (CM) energy spread of the e+e- collisions can be reduced from ~50 MeV to a level comparable to the Higgs boson’s natural width of ~4 MeV.

Optimized injector schemes for FCC-ee positron production
/ Bai, B (Beijing, Inst. High Energy Phys. ; IJCLab, Orsay ; Beijing, GUCAS) ; Faus-Golfe, A (IJCLab, Orsay) ; Han, Y (IJCLab, Orsay) ; Chaikovska, I (IJCLab, Orsay) ; Zhou, Z (Beijing, Inst. High Energy Phys.) ; Chi, Y (Beijing, Inst. High Energy Phys.) ; Oide, K (CERN ; KEK, Tsukuba) ; Zimmermann, F (CERN)
Injectors and in particular the positron production systems are a crucial element in linear and circular colliders. The proposed FCC-ee injector linac accelerates both electrons and positrons up to 6 GeV in order to be injected into the Pre-Booster Ring (PBR) with a high intensity of 3.5 nC per bunch for the Z running mode.

The Platform for Research and Applications with Electrons (PRAE) is a multidisciplinary R&D; facility gathering subatomic physics, instrumentation, radiobiology and clinical research around a high-performance electron accelerator with beam energies up to 70 MeV. In this paper we report the complete optics design and performance evaluation of a Very High Energy Electron (VHEE) innovative radiobiology study, in particular by using Grid mini-beam and FLASH methodologies, which could represent a major breakthrough in Radiation Therapy (RT) treatment modality..
