Abstract :
For the feasibility study of a superconducting damped cavity for a KEK B-factory, a prototype module was constructed and tested in the TRISTAN Accumulation Ring. This module accelerated the beam current of 500 mA with the cavity voltage of 1-2 MV, and 350 mA with 2.5 MV (10.3 MV/m). These currents were limited by heating up of other ring components. The peak current of 573 mA was achieved in 16 bunches with 1.2 MV
