High-power Testing of the First Pep-ii Rf Cavity
نویسندگان
چکیده
This paper describes the high-power testing of the first RF cavity for the PEP-II Bfactory. The cavity is designed for continuous operation at 476 MHz with up to 150 kW wall dissipation and heavy beam loading. Three rectangular waveguides and broad-band loads are used to damp the cavity higher-order modes. The test configuration, RF conditioning history and high-power performance are described and plans for processing of the production run of cavities are discussed.

Updated Impedance Estimate of the Pep-ii Rf Cavity
This paper presents an updated estimate of the higher-order mode impedance spectrum of the RF cavities for the PEP-II B-factory. The cavity is designed for continuous operation at 476 MHz with up to 150 kW wall dissipation and heavy beam loading. To reduce the growth rates of coupled-bunch instabilities the cavity higher-order modes are damped by three rectangular waveguides and broad-band load...
متن کاملCommissioning of the PEP-II High Power RF Systems
We describe the commissioning of the high-power RF stations for the PEP-II B factory. This includes in-situ testing and conditioning of components after installation, phasing of cavities within each station and between stations in each ring, capture of fist beam, stored-beam operation at lowand moderatecurrent, commissioning of feedback loops, and high-current operation. Performance of the over...
متن کاملA High-power L-band Rf Window*
This paper discusses the design, fabrication and testing of a high power alumina disk window in WR1500 waveguide at L Band, suitable for use in the NLC damping ring RF cavities at 714 MHz and the LEDA Accelerator at 700 MHz. The design is based on the fabrication methods used for the successful PEP-II cavity windows. Four prototype windows at 700 MHz have been produced by LBNL for testing at LA...
متن کاملSPEAR II and PEP Klystron Parameters PEP Klystron Interaction Space Parameters SPEAR II PEP
The 125 kW CW klystrons to be described in the first part of this paper were specifically designed for energy upgrading of the electron-positron storage ring, SPEAR II, at SLAC. Four tubes are required with an efficiency greater than 50 percent. The operating frequency is 358.54 MHz. The gain is approximately 50 dB, the operating voltage is 41 kV and the microperveance is 0.7. The klystron must...
متن کاملArc Detection and Interlock Module for the Pep-ii Low Level Rf System*
A new arc detection and interlock generating module for the SLAC PEP-II low-level RF VXI-based system has been developed. The system is required to turn off the RF drive and high voltage power supply in the event of arcing in the cavity windows, klystron window, or circulator. Infrared photodiodes receive arc signals through radiation resistant optical fibers. Gain and bandwidth are selectable ...
