Simulation of beam loading compensation with RF-Track
/ Olivares Herrador, Javier (CERN ; Valencia U., IFIC) ; Latina, Andrea (CERN) ; Gimeno-Martinez, Benito (Valencia U., IFIC) ; Esperante Pereira, Daniel (Valencia U., IFIC) ; Fuster-Martinez, Nuria (Valencia U., IFIC) ; Zhao, Yongke (CERN)
The beam loading effect results in a gradient reduction of accelerating structures due to the excitation of the fundamental mode when the beam travels through the cavity. A recent implementation of this process in the tracking code RF-Track allows the simulation of realistic scenarios, thus revealing the impact of this phenomenon in start-to-end accelerator designs.

Radiation Load Studies for the FCC-ee Positron Source with a Superconducting Matching Device
/ Humann, Barbara (Vienna U. ; CERN) ; Auchmann, Bernhard (PSI, Villigen) ; Chaikovska, Iryna (IJCLab, Orsay) ; Kosse, Jaap (PSI, Villigen) ; Latina, Andrea (CERN) ; Lechner, Anton (CERN) ; Ogur, Salim (IJCLab, Orsay) ; Zhao, Yongke (CERN)
For an electron-positron collider like FCC-ee, the production of positrons plays a crucial role. One of the design options considered for the FCC-ee positron source employs a superconducting solenoid made of HTS coils as an adiabatic matching device. [...]

Optimisation of the FCC-ee Positron Source Using a HTS Solenoid Matching Device
/ Zhao, Yongke (CERN) ; Auchmann, Bernhard (PSI, Villigen) ; Chaikovska, Iryna (IJCLab, Orsay) ; Chehab, Robert (IJCLab, Orsay) ; Craievich, Paolo (PSI, Villigen) ; Döbert, Steffen (CERN) ; Duda, Michal (Cracow, INP) ; Kosse, Jaap (PSI, Villigen) ; Latina, Andrea (CERN) ; Martyshkin, Pavel (Novosibirsk, IYF) et al.
In this paper, we present the simulation and optimisation of the FCC-ee positron source, where a high-temperature superconducting (HTS) solenoid is used as the matching device to collect positrons from the target. The "conventional" target scheme is used which simply consists of amorphous tungsten. [...]

The FCCee Pre-Injector Complex

The international FCC study group published in 2019 a Conceptual Design Report for an electron-positron collider with a centre-of-mass energy from 90 to 365 GeV with a beam currents of up to 1.4 A per beam. The high beam current of this collider create challenging requirements on the injection chain and all aspects of the linac need to be carefully reconsidered and revisited, including the injection time structure.

A Start-to-End Optimisation Strategy for the CompactLight Accelerator Beamline
/ Zhao, Yongke (CERN) ; Aksoy, Avni (Ankara U. ; CERN) ; Castañeda Cortés, Hector Mauricio (Cockcroft Inst. Accel. Sci. Tech.) ; Dunning, David (Cockcroft Inst. Accel. Sci. Tech.) ; Latina, Andrea (CERN) ; Thompson, Neil (Cockcroft Inst. Accel. Sci. Tech.)
The CompactLight collaboration designed a compact and cost-effective hard X-ray FEL facility, complemented by a soft X-ray option, based on X-band acceleration, capable of operating at 1 kHz pulse repetition rate. In this paper, we present a new simple start-to-end optimisation strategy that is developed for the CompactLight accelerator beamline, focusing on the hard X-ray mode. [...]
