Abstract :
A construction program for an RF cavity for the LNLS storage ring is under development. The cavity main frequency is 476 MHz, and should operate with 60 kW CW. The cavity design is based on the development made for the proposed PEP II B factory. Special wave guide dampers are used in order to reduce HOM instabilities. In order to get the precise mechanical dimensions of the 476 MHz cavity, a scaled prototype (approximately 1200 MHz) was built based on the results of numerical simulation. Low power tests were used to fully characterize the HOM spectrum. Using the measured values, couple-bunch instabilities are studied
