Abstract :
We studied the beam loading effects on the High Gradient Cavity (HGC) loaded with Magnetic Alloy (MA) by multiparticle tracking simulation. The Q-value of the cavity is variable from 0.6 to more than 10. From the view point of multi-bunch effect, it was found that either very high Q-value or low Q-value was preferable to suppress the periodic transient beam loading. The experimental results of the beam loading compensation using an electron beam are also described
