It consists f an electron-cyclotron-resonance ion-source (ECRIS)and two linacs, which are a radio-frequency-quadrupole (RFQ) linac and an Interdigital H-mode drift-tube-linac results, as reported earlier. Because the method of alternating-phase-facusing (APF) was used for beam focusing of the IH-DTL, the motion of beam ions would be sensitive to gap-voltage errors, caused during tuning of the gap-voltage distribution and by auto-matic-frequency tuning in actual operation. To study the effects of voltage errors to beam quality, further measurements were performed during acceleration tests. In this report, the effects of voltage errors for the APF IH-DTL are discuseed.}, pages = {2150--2156}, title = {Effects of voltage errors caused by gap-voltage and automatic-frequency tuing in an alternating-phase-focused linac}, volume = {266}, year = {2008} }
