Fast Trigger System for Beam Abort System in SuperKEKB

Autor: Ikeda, Hitomi, Mimashi, Toshihiro, Nakamura, Shu, Oki, Toshiyuki, Sasaki, Shinya

In order to protect the hardware components of the de-tector and accelerator from sudden beam loss of high beam currents, the fast beam abort system is developed in the SuperKEKB. The previous abort system was not fast enough for sudden beam loss tha
