Beam Instrumentations and Commissioning of Linac in CSNS

China Spallation Neutron Source(CSNS), the biggest platform for neutron scattering research in China, will be finished built and run in the end of 2017. It mainly consists of a 80MeV H⁻ linac and a 80MeV to 1.6GeV Rapid Cycling Synchrotron, two beam transport lines, one target station and relative ancillary facilities. The Linac beam commissioning with beam loss monitors, current transformers, BPMs, beam profile monitors and beam emission measurement has been the main task since last year. Beam instrumentations, commissioning of the temperary 60 MeV linac will be discussed in this paper.
