| WEP81 | Tests of air cooled 1.3 GHz waveguide windows using a RF coupler test bench based on a resonant ring | 705 |
| ||
| A new coupler test bench based on a resonant ring has been built at ELBE in Dresden-Rossendorf to run window as well as coupler tests with RF power up to 100 kW. The ring is driven by a 10 kW klystron. This test bench includes also liquid nitrogen cooling of the ceramic cold window of the RF-coupler which allows testing under almost real conditions. A special waveguide was designed to match couplers with different antenna tips. In a first step the waveguide window has been equipped with additional air-cooling and tested. The design of the test bench and the gained experience with warm window tests at the resonant ring as far as it could be collected within a short time of operation will be reported. |
