Abstract :
Using the 3-D wakefield calculation program MAFIA, the longitudinal loss factor (energy lost by the beam) and the transverse loss factor (transverse kick experienced by the beam) are systematically studied with the depth and the length of a slot as parameter values. When the bunch is longer than the slot, it is found that simulation results agree with the early theoretical prediction by M. Sands (1977). The loss factor decreases exponentially as the slot gets deeper. However, when the bunch is shorter than the slot, it is found that the longitudinal loss factor decreases but the transverse loss factor does not change very much as the slot gets longer.<>
