| 摘 要： | 加速管中的高次模（HOM）能导至累积束流崩溃，因此这些模式必须被抑制．在S波段直线对撞机中（SBLC），采用了在束流孔膜片上复盖适当的损耗材料的方式．HOM的Q值被减小了5倍，而基模的Q值几乎保持不变．3种材料被考虑，即：stainlesssteel，kanthal和galvedc为了对具有这种涂层的加速腔进行高功率测试，一个两腔的谐振器结构被设计．本文描述了高功率测试的原理，过程以及初步的结果．

| 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. |
