Abstract：
The excitation of Higher, Order Modes (HOM) in an accelerator can lead to cumulative beam break up, therefore, these modes have to be suppressed. For the S-Band Linear Collider (SBLC), it has been suggested to cover the disk loaded strucks at the iris with an aPPropriate loss malarial. For the high-power test of the iris coating a resonator consishng of tWo cells of the SBLC is used. This paper describes the high-power test and gives some Preliminary results.
