Abstract :
The National Spallation Neutron Source (NSNS) requires a linac that accelerates a H- beam to 1.0 GeV. The NSNS linac starts with a radio-frequency quadrupole (RFQ) accelerator; which is followed by a drift-tube linac (DTL), a coupled-cavity drift-tube linac (CCDTL), and conventional coupled-cavity linac (CCL). In this paper, we focus on the DTL, CCDTL, and CCL parts of the accelerator. We discuss the linac design parameters and beam dynamics issues. The design rationale of no separate matching sections between different accelerating sections maintains the current independence of beam behavior
