Background The tune is one of the most important parameters of the storage ring which play a crucial role in the brightness optimization.The synchrotron radiation will suppress the oscillation and make the detection u...
Background The upgrade project of the Beijing Electron Positron Collider(BEPCII)is a high-current electron–positron collider with beam intensity close to 1A.The RF system plays an important role in providing energy f...
Background The cryogenic control system of BEPCII has been in stable operation for more than 10 years,providing techni-cal support for the generation of cryogenic environments.The core hardware of the cryogenic contro...
Background The current strategy to achieve high luminosity for high energy physics experiments is to store huge currents distributed in many bunches in circular machines such as BEPCII,so the longitudinal coupled bunc...
Objective BEPCII is a high-performance collider with a design energy of 2.1 GeV. In order to obtain more physical experimentsand synchrotron radiation applications, BEPCII decided to carry out energy upgrading to 2.5 ...
