The NSLS-II is a new 3rd generation light source being designed at Brookhaven. A key design feature is a large circumference with soft (25m radius) bends which enable damping wigglers to reduce the emittance from 2.1nm-rad to <1nm-rad. The RF power requirement is dominated by the wiggler radiation, and the storage ring RF system is installed in stages as damping wigglers are added.

The first phase of the upgrade of the RF System of Elettra is completed. The 500 MHz 150 kW cw plant has been installed and is in operation on the machine. The 150 kW amplifier is based on the combination of two 80 kW IOTs. After a recall of the targets of the project, this presentation gives a review of the performances of the system and reports on the experience during the commissioning and...

A fan-out power distribution algorithm with RF vector control using reactive transmission line circuit parameters for maximum power efficiency is presented. If a fixed power splitting system with individual cavity voltage control at each cavity input is used, the power efficiency becomes lower since the RF power source must deliver more power than needed by cavities. The proposed fan-out power...
