The First Beam Recirculation and Beam Tuning in the Compact ERL at KEK
/ 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. [...]

Reconstruction of Photon Factory Storage Ring for the Straight-Sections Upgrade Project
/ Honda, Tohru ; Asaoka, Seiji ; Haga, Kaiichi ; Harada, Kentaro ; Hori, Yoichiro ; Izawa, Masaaki ; Kasuga, Toshio ; Kobayashi, Yukinori ; Maezawa, Hideki ; Mishina, Atsushi et al.
The Photon Factory (PF) storage ring is a 2.5-GeV synchrotron light source at KEK. In 1997, we have accomplished a large reconstruction of the ring in order to reduce the beam emittance from 130 nm rad to 36 nm rad. [...]

Beam Injection for the PF-AR with a Single Pulsed Quadrupole Magnet
/ Harada, Kentaro ; Kobayashi, Yukinori ; Mitsuhashi, Toshiyuki ; Miyajima, Tsukasa ; Nagahashi, Shinya ; Obina, Takashi ; Ueda, Akira
We develop the injection system for PF-AR (Photon Factory Advanced Ring for Pulsed X-ray) with single pulse quadrupole (PQ) magnet without pulse local bump of the stored beam with four dipole kickers. The pulse quadrupole magnet has the length of 30cm, the field gradient of 3T/m, half-sine-form pulse width of 2.4mSec, measured inductance of 1.8mH and the peak current of about 2000A. [...]
