Solid state amplifiers 2: Solid state amplifiers 2
- Jorn Jacob (ESRF)
Further to our communication at last CWRF, a 85kW solid state amplifier has been designed, assembled and tested at ESRF up to 90kW. Its operation frequency is 352.2MHz. It features a cylindrical cavity to combine the RF power coming from its 132 modules. Details will be given on its construction, and test results both for CW and pulse modes.
The talk will explain the reasons why CERN signed a contract for the procurement of two 2 MW peak power amplifiers based on SSPA technology.
Comparison that has been made with other technologies (tetrodes, IOT, Diacrodes, Klystrons) will be explained.
Basic principles of the chosen solution will be given.
Development of a solid state amplifier (SSA) is planned for a 509 MHz accelerator cavity at the SPring-8 storage ring, as an optional plan of the upgrade project. Instead of the present power distribution system using a 1.2 MW klystron, a 100 kW SSA drives each of acceleration cavities. This system enables us to control the power and phase of the cavity, which gives us the redundancy, better...
Solid-state high power amplifiers are increasingly used in particle accelerators as drivers and as high power stages themselves. In this context, at FREIA, we are developing a 10 kW pulsed power amplifier at 352 MHz. The frequency and pulsed operation (3.5 ms pulse at 14 Hz repetition) correspond to the specifications of the European Spallation Source (ESS), which we assist in its development...
