摘要： As the ion beam is accelerated, the radii of the closed orbits gradually increase, and the centers thereof move in a direction approaching the peripheral edge portion along a predetermined radial direction of the cavity, and upon reversing the direction of movement, move further toward the center of the cavity. The intensity distribution in the orbital plane of the main magnetic field is designed to realize the foregoing feature. Thus, an accelerator is provided that is compact and that enables the energy of an extracted beam to be changed, that enhances the efficiency of beam injection into the accelerator from an external ion source, and that improves a dose rate of the resulting extracted ion beam.

摘要： A motion control device independently drives left and right wheels by calculating a wheel torque value from a difference between a reference vehicle state quantity calculated from driver operation information or an operation instruction of a higher driving device and an actual vehicle state quantity calculated from information regarding a motion and a posture of the vehicle, and controlling a plurality of motors based on the wheel torque value. Furthermore, the motion control device calculates a momentum error from a difference between a reference momentum calculated based on a wheel rotation speed and a tire steering angle and an actual momentum calculated based on the information regarding the motion and the posture of the vehicle, extracts a momentum error caused by a torque difference of the motor from the calculated momentum error, calculates a wheel torque correction amount based on the extracted momentum error caused by the torque difference of the motor, adds the wheel torque correction amount to the wheel torque value, and outputs a wheel torque command to the plurality of motors.
