Since the tapered quarter wave resonator (QWR) cavity is proven to have a much lower peak surface magnetic field in the short plate and a lower peak surface electric field near the beam tube compared with the straig...
A new RIB project, the Beijing Radioactive Ion-beam Facility (BRIF), has been running at CIAE since 2004. In this project, a 100 MeV H-cyclotron, CYCIAE-100, is selected as the driving accelerator providing a 75-100...
1 Introduction Several tests have been done in the QWR cavity sputtering system since the system was established in 2009.The sputtering system is checked out in these tests and the uniformity of sputtered film is mea...
1 Introduction Four superconducting QWR cavities will be used in HI-13 tandem accelerator upgrade project (BRIF). These niobium coated cavities will be produced by CIAE. Up to now, a niobium
