Abstract :
The design of the ALS (Advanced Light Source) storage ring 500-MHz cavity has been modeled with Mafia and Urmel codes. The effects of the holes cut for the drive port, the higher-order mode damping port, the probe port, and tuner were modeled with the Mafia codes. The frequency dependence on the shape and spacing of the nose cones and the general shape of the cavity were modeled with Urmel codes. The modeling results agree with those of the operating SRS cavity fairly well. The shape of the cavity and the nose cones and their spacing have been confirmed with the codes. The power dissipation at various parts of the cavity has also been examined. The power dissipation map should help in the cavity cooling system design
