KEK-ATF is studying low emittance, multi-bunch electron beam for the future linear collider. The energy instability of the 1.5 GeV linac has been a problem making the beam injection to the damping ring unstable. Because the unstable beam generates also large amount of the radiation, the beam current is limited by the KEK radiation safety policy much lower than what we expect. Stabilizing the S-...

Spallation sources dedicated to neutron scattering experiments, as well as multi-purpose facilities serving several applications call for pulsed mode operation of a high intensity proton linac. There is general agreement on the superconducting technology for the high-energy part, which offers some advantages, like higher gradient capabilities or operational costs reduction, as compared to room-...

Abstract As far as integrity and proper operation of a flying vehicle are concerned, modal analysis the wing is crucial design procedure. This procedure aims to define natural frequencies structure avoid resonance under fluctuating aerodynamic loads. becomes more significant if forced perform pitching oscillation. The present study dynamic behavior rectangular with NACA 0009 airfoil using Euler...
