The carbon gantry consists of ten combined-function superconducting magnets, allowing a very compact geometry – the length and the radius of the gantry are approximately 13 and 5.5 m, respectively, comparable to the dimensions of existing proton gantries. Further, these superconducting magnets are designed for fast slewing of the magnetic field to follow the multiple flattop operation of the synchrotron. In this paper, the recent developments of HIMAC are presented.}, title = {SUPERCONDUCTING GANTRY AND OTHER DEVELOPMENTS AT HIMAC}, year = {2013} }
