CEPC Technical Design Report: Accelerator
/ CEPC Study Group Collaboration
The Circular Electron Positron Collider (CEPC) is a large scientific project initiated and hosted by China, fostered through extensive collaboration with international partners. The complex comprises four accelerators: a 30 GeV Linac, a 1.1 GeV Damping Ring, a Booster capable of achieving energies up to 180 GeV, and a Collider operating at varying energy modes (Z, W, H, and ttbar).

Development of a a YAG/OTR Monitor
/ Yang, Renjun (Orsay, LAL) ; Aryshev, Alexander (KEK, Tsukuba) ; Bambade, Philip (Orsay, LAL) ; Bergamaschi, Michele (CERN) ; Naito, Takashi (KEK, Tsukuba) ; Terunuma, Nobuhiro (KEK, Tsukuba) ; Wallon, Sandry (Orsay, LAL)
To investigate the mechanisms of beam halo formation and its dynamics, a YAG/OTR monitor has been developed and tested at the KEK-ATF. The monitor has four ceramic Ce:YAG screens for the visualization of the beam core and beam halo and an OTR target to provide complementary beam core measurements. [...]

Performance of Nanometre-Level Resolution Cavity Beam Position Monitors and Their Application in an Intra-Train Beam Position Feedback System
/ Blaskovic Kraljevic, Neven (JAI, UK) ; Bambade, Philip (Orsay, LAL) ; Bett, Douglas (CERN) ; Bromwich, Talitha (JAI, UK) ; Burrows, Philip (JAI, UK) ; Christian, Glenn (JAI, UK) ; Jang, Si-Won (Korea U.) ; Perry, Colin (JAI, UK) ; Ramjiawan, Rebecca (JAI, UK) ; Tauchi, Toshiaki (KEK, Tsukuba) et al.
A system of three low-Q cavity beam position monitors (BPMs), installed in the interaction point (IP) region of the Accelerator Test Facility (ATF2) at KEK, has been designed and optimised for nanometre-level beam position resolution. The BPMs have been used to provide an input to a low-latency, intra-train beam position feedback system consisting of a digital feedback board and a custom stripline kicker with power amplifier.
