Abstract
The project of proton treatment facility at the National Cancer Center Hospital East (NCC, Kashiwa) is proceeding on schedule. This paper presents up - to - date status of our project. Building construction started in May,1996, and completed at the end of March,1997. Equipment manufacturing has proceeded very well, and the most of them, including 235MeV isochronous cyclotron, two isocentrically rotational gantries and fixed horizontal beam delivery system, has already been installed into the building. Part of hardware and software are now under developing. Problems of our project are also discussed in this article.
