SYSTÈME D'INJECTION POUR SYNCHROTRON ET PROCÉDÉ DE FONCTIONNEMENT POUR ACCÉLÉRATEUR LINÉAIRE À TUBE DE GLISSEMENT

摘要

When accelerating first ions, radio frequency power is fed to a drift tube linear accelerator so that the phase difference between an accelerating half cycle for accelerating the first ions in one of the plurality of drift tube gaps and the accelerating half cycle for accelerating the accelerated first ions reaching the next drift tube gap is set to a first accelerating cycle phase difference; and when accelerating second ions having a charge-to-mass ratio lower than the first ions, the radio frequency power is fed to the drift tube linear accelerator so that the phase difference between an accelerating half cycle for accelerating the second ions in the one drift tube gap and the accelerating half cycle for the accelerated second ions reaching the next drift tube gap is set to a second accelerating cycle phase difference that is larger than the first accelerating cycle phase difference.
