CiADS is the world’s first Accelerator Driven System with a Mega-watt beam power. The linac of CiADS consists of a 500 MeV and 5 mA with five-family superconducting resonators located directly downstream of the Radio Frequency Quadrupole (RFQ). The most significant challenge in designing the superconducting linac for CiADS is to ensure high-reliability operation with minimal beam loss control at 10-7 level and availability maximization through specifically designed hardware and software. In this presentation, we will discuss the physical design of the superconducting linac, including the fault compensation based on beam loss control and beam loss analysis during commissioning .

At this moment, the Spallation Neutron Source linac accelerates H⁻ ions to 1.05 GeV before they injected into the ring. The beam power on the target is 1.7 MW. The linac includes three main parts - a front-end with ion source, RFQ, and Medium Energy Beam Transport (MEBT) section; a normal temperature linac with Drift Tube Linac (DTL) and Coupled Cavities Linac (CCL); and superconducting linac (SCL). The linac has been in operation since it was commissioned in 2005. This talk discusses the results of beam dynamics studies, existing diagnostic devices, simulation codes and models used in analysis, development and results of linac tuning procedures, and beam loss reduction efforts performed at the SNS linac for 18 years. Considerations about future beam physics experiments and simulations software improvements are presented.
