Abstract :
In the framework of the IFMIF (International Fusion Material Irradiation Facility) project study particle dynamics calculations have been performed for a 175 MHz, 125 mA deuteron linac. The linac has to provide a 40 MeV beam with low losses and small emittance growth for the homogenous irradiation of a Li target. The linac consists of an RFQ injector followed by a drift tube linac. The complete facility would need in parallel operation two 125 mA linac. In a first attempt the particle dynamics layout of an Alvarez type DTL has been studied aiming for low RF voltages and moderate power losses in the structure due to the required CW operation. In addition first investigations have been started for an H-type DTL to further evaluate the capability of this structure for the acceleration of high intensity beams. Results will be presented and discussed including matching requirements to the DTL
