The KEK injector Linac feeds beams to four rings. It is called J-Linac. SuperKEKB Main Rings are High-Energy-Ring (HER) and Low-Energy-Ring (LER). The Linac injects a 7.0 GeV electron beam to HER and a 4.0 GeV positron beam to LER. It also injects el

PF-AR was constructed as an accumulator ring for TRISTAN, and in the KEKB era it has been revitalized as a 6.5 GeV synchrotron radiation source. The injection energy was 3 GeV and the beam was accelerated to 6.5 GeV prior to the user run. The origina

Large-aperture Travelling-wave Accelerator Structure for Positron Capture of SuperKEKB Injector Linac

Autor: Matsumoto, Shuji, Higo, Toshiyasu, Kakihara, Kazuhisa, Kamitani, Takuya, Tanaka, Madoka

Comparing to the previous KEKB, the four-times higher charge of 4 nC per bunch is required for the injector linac of SuperKEKB. Not only a flux concentrator will be introduced but also the physical aperture of the downstream six 2m-long accelerator s
