  One system to transfer liquid nitrogen (LN2) will be installed at TPS in 2015 for beamline. This system includes two transfer lines (length 600 m), eight keep-full devices and 26 branch lines with 26 control valves for 24 straight sections of beam lines. The required consumption of LN2 for each beam line is 30 L/h. An archive system was developed to monitor and to calculate the consumption of LN2 for each beam line. This consumption was calculated based on the pressure difference and the flow coefficient (Kv) of the control valve. This paper presents the configuration of the LN2 supply system at NSRRC and a test bench of the calculation of LN2 consumption. A simple test result is presented and discussed.

  A 499 MHz deflecting cavity has been designed as a three-way beam spreader to separate an electron beam into 3 beams. The rf tests carried out on the superconducting rf-dipole cavity have demonstrated that a transverse voltage of 4.2 MV can be achieved with a single cavity. This paper discusses the beam dynamics on a deflecting structure operating in continuous-wave mode with a relativistic beam. The study includes the analysis on emittance growth, energy spread, and change in bunch size including effects due to field non-uniformities.
