1.INFLUENCE OF BEAM ENERGY SPREAD AND CHANGES OF CHANNEL APERTURE ON BEAM WAKEFIELD
3.The maximum current density can be higher than 100 μA/cm 2 at 100 eV,but decreases to 10～20 μA/cm 2 at 10 eV.The energy spread of the system is ±0 5 eV.The ion mass and energy can be measured by QMS and CMA analyzers respectively,the ion current and current density distributions can be measured by the two Faraday cups mounted on the target.
4.A study for determining the multi-energy Point Spread Function (PSF), root mean square radius of aberration and electron optical Modulation Transfer Function (MTF) in cathode lenses by means of a geometric figure of three dimensional coordinate has been fully described in the paper.
9.The beam from KEK carries higher-energy neutrinos, which can be spotted easily even with the surviving tubes spread more sparsely across the detector.
10.In recent years on nuclear physics and allied discipline fundamental research, nuclear energy and nuclear science technical application middle big city lodge versus spread solstice still wide nuclide section, continue to still width energy region appraise nuclear data extend still width energy region need for, , considering these region experiment nuclear data pinch, hence appraise nuclear data won can but through the medium of model theory .
