| 内容記述 | A novel ion accelerator referred to as a digital accelerator, which is based on the<br /> induction synchrotron concept, is discussed here. Its operational performance is the<br /> same as that of the induction synchrotron, where acceleration and confinement of ions<br /> in the propagation direction are implemented independently with a pulsed voltage and<br /> the so-called barrier voltages. These voltage pulses are generated in the induction<br /> acceleration cell energized by the switching power supply, which is triggered with a<br /> trigger signal manipulated by an ion-bunch signal. In the digital accelerator, any ion<br /> species with its possible charge state can be accelerated since the acceleration voltage<br /> pulse generation is always synchronized with the ion circulation. Acceleration of <br />argon ions is planned as a proof-of-principle experiment at KEK. The detailed aspects<br /> of the digital accelerator are described, including theoretical backgrounds such as<br /> beam dynamics. <br /><br /> The KEK-PS booster synchrotron is under renovation, aiming to become the first <br /> digital accelerator. The KEK Booster is a rapid-cycle synchrotron where the acceleration<br /> voltage amplitude changes dynamically throughout the acceleration <br />period. The existing induction cells can provide a peak output voltage of 2 kV in 250 <br />nsec pulse width at a maximum repetition rate of 1 MHz. Once the peak output<br /> voltage is fixed, it is difficult to change its magnitude in the same acceleration cycle. <br /> The main purpose of this thesis is to propose the realization of a dynamically<br /> changeable acceleration voltage by employing the induction acceleration system. In<br /> fact, this idea has been developed for the KEK digital accelerator. The acceleration<br /> period is divided into stages, where different acceleration voltages, pulse widths, and<br /> repetition rates are required. A novel technique, which consists of staging of the<br /> acceleration period, systematic sorting of the induction acceleration cells, and<br /> intermittent operation of the induction acceleration systems, has been developed. <br /> Particle tracking simulations in the longitudinal direction were performed in order to<br /> verify the feasibility of the scheme. The acceleration scheme has been verified<br /> experimentally for the first two stages of the acceleration period by using a beam<br /> simulator signal. The results will be presented here and the perspectives of this<br /> technique will be discussed. | |||||
