/ Sakanaka, Shogo ; Adachi, Masahiro ; Adachi, Shin-ichi ; Akemoto, Mitsuo ; Arakawa, Dai ; Asaoka, Seiji ; Enami, Kazuhiro ; Endo, Kuninori ; Fukuda, Shigeki ; Furuya, Takaaki et al.
Superconducting(SC)-linac-based light sources, which can produce ultra-brilliant photon beams in CW operation, are attracting worldwide attention. In KEK, we have been conducting R&D; efforts towards the energy-recovery-linac(ERL)-based light source* since 2006. [...]

The machine commissioning of KEKB started in December 1998 and its operation was terminated at the end of June 2010 to upgrade KEKB to SuperKEKB. In this paper, we summarize the history of KEKB and show the achievements made there..

Lattice design for the LHEC recirculating LINAC
/ Sun, Y P (SLAC) ; Adolphsen, C (SLAC) ; Lund Eide, A (CERN) ; Zimmermann, F (CERN)
In this paper, we present a lattice design for the Large Hadron Electron Collider (LHeC) recirculating linac. The recirculating linac consists of one roughly 3-km long linac hosting superconducting RF (SRF) accelerating cavities, two arcs and one transfer line for the recirculation. [...]

PERLE - Lattice Design and Beam Dynamics Studies
/ Bogacz, Alex (Jefferson Lab) ; Angal-Kalinin, Deepa (Daresbury) ; Arduini, Gianluigi (CERN) ; Bousson, Sébastien (Orsay, IPN) ; Brüning, Oliver (CERN) ; Calaga, Rama (CERN) ; Chaikovska, Iryna (Orsay, LAL) ; Douglas, David (Jefferson Lab) ; Dr Schirm, Karl-Martin (CERN) ; Gerigk, Frank (CERN) et al.
PERLE (Powerful ERL for Experiments) is a novel ERL test facility, initially proposed to validate choices for a 60 GeV ERL foreseen in the design of the LHeC and the FCC-eh. Its main thrust is to probe high current, CW, multi-pass operation with superconducting cavities at 802 MHz (and perhaps testing other frequencies of interest). [...]
