The storage ring is feed from a full-energy 249.6 m booster ring preceded by a 100 MeV LINAC that acelerates electrons from a 100KeV electron gun. The electron gun, the LINAC, the booster ring and the storage ring are enclosed in a high density BaSO4-filled concrete bunker (tunnel-like) provided with a high capacity dedicated HVAC system aimed to keep temperature stable within a very narrow ran ...

Circular Electron-Positron Collider (CEPC) is a 100 km ring e+ e- collider for a Higgs factory. The injector is composed of Linac and Booster. Luminosity is the core and key parameter of the collider. High integral luminosi-ty is the pursuit of CEPC design, so the top-up injection scheme, long running time and high availability is neces-sary. As the first part of injector, high availability of the ... More

The target is a key part of the CSNS facility, which bears the average beam power of 100KW to 500KW. Beam position on the target must be strictly controlled to avoid damage to the target. The target imaging system can give the position and size on the target, but it is difficult to observe the signal in single shot mode and it become insensitive over time. In this paper, we propose to estimate ... More
