Abstract :
The ALS storage ring RF system is characterized by the use of the following features: 1. high power loading of two single cell cavities. 2. The use of a tubular ceramic input window employing aperture coupling. 3. The use of waveguide filters and matchers designed for HOM absorption. 4. A comprehensive HOM monitoring system. 5. The use of waveguide water-wedge loads for the magic tee and circulator loads. The results of cavity measurements and high power tests are reported together with the performance of the system during the commissioning and operation phases of the ALS project. Plans for future window development are discussed
