Solid state amplifiers 3: Solid state amplifiers 3
- Patrick Marchand (Synchrotron SOLEIL)
Solid state rf amplifier development is underway at the Advanced Photon Source at two operating frequencies. A new 9.77-MHz solid state driver amplifier was designed and built to replace existing obsolete driver amplifiers presently used in the Advanced Photon Source accumulator ring rf systems. The amplifier design uses a single 1.25kW LDMOS push-pull transistor output device operating at...
At the FREIA laboratory, we develop and test high power RF equipment for the linear accelerator of the European Spallation Source (ESS). In this respect, we develop high power RF amplifiers based on the Laterally Diffused Metal Oxide (LDMOS) semiconductor technology. The purpose of this paper is to present a time domain characterization methodology for high-power pulsed amplifiers. A...
Amplifiers for Broadcast applications with RF output power in the range of 100kW was a domain of tube (IOT) amplifiers.
Since innovative and powerful LDMOS transistors are available, IOT amplifiers are being replaced by solid state.
Efficiency and size of modern LDMOS-amplifiers are very competitive and not worse than tube based amplifiers anymore.
The big advantage to use LDMOS technology...
This presentation will give a view on an installation, a commissioning process and first operational experience related to injector’s acceleration components and cavities in storage ring with their RF power sources and transmission lines at Solaris synchrotron. Solaris injector’s RF stations uses one K1-type solid state pulsed modulator with S-band 10MW Thales klystron for RF thermionic gun...
