As SNS undergoes construction, many detailed questions arise concerning strategies for commissioning and operating the accumulator ring. The ORBIT Code is proving to be an indispensible tool for addressing these questions and for providing guidance to the physicists and decision makers as operation draws near. This paper shows the application of ORBIT to a number of ring issues including exclusion of the HEBT RF cavities during commissioning, the detailed effect of the injection chicane magnets on the beam, the effects and correction of magnet alignment and multipole errors, debunching of the linac 402.5 MHz beam structure, the injection of self consistent uniform beam configurations, and initial electron cloud simulations.

A 150MeV proton FFAG (Fixed Field Alternating Gradient) synchrotron has been constructed to be a prototype for various applications such as proton beam therapy. At the moment, all the components are assembled, and multi-turn injection and beam storage were successfully performed. We are in the phase of beam acceleration up to final energy and expect the beam extraction in a few months. In this paper, beam commissioning results such as multi-turn injection, orbit correction, tune survey and optimization of RF gymnastics will be presented.

Since 1994, the clinical trial at HIMAC has been successfully being progressed and more than 1,700 patients have treated with carbon ions. Owing to the good result of HIMAC, several medical groups in Japan have strongly required the carbon therapy facility. Based on the development of accelerator and the irradiation technologies for 10 years, therefore, we started to design a carbon therapy facility in Japan. The accelerator complex for the facility consists of two ECR ion sources with permanent magnets, an injector linac cascade (RFQ+IH) with the energy of 4 MeV/n, a synchrotron ring with the maximum energy of 400 MeV/n and beam delivery system for three treatment rooms. The R&D for the new facility has been already approved and will be started from April 2004. We will describe the conceptual design of the new facility.
