Abstract

An rf cavity for 150 MeV FFAG (Fixed Field Alternating Gradient) proton synchrotron has been developed. The rf cavity consists of four pieces of MA (Magnetic Alloy) core. These MA cores are indirectly cooled by thermally conductive spacers and cooling plates. One piece of MA core (Wide: 1700 mm, Height: 950 mm, Length: 25 mm) is mechanically supported by a cooling plate. The range of acceleration frequency is 1.5 MHz to 4.6 MHz. The acceleration voltage of 19 kV and the acceleration cycle of 250 Hz are required. A couple of rf stations are proposed to install in the 150 MeV FFAG. Recent developments on the radio frequency acceleration system for 150 MeV FFAG proton synchrotron are presented.
