Commissioning of the PEP-II High Power RF Systems
نویسندگان
چکیده
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 overall system and of critical components such as klystrons, cavities, windows, tuners and the HOM suppression scheme is reported. Observation of beam motion and signals in the cavity and HOM loads suggest that the HOM impedance reduction necessary for high-current operation has been achieved.

Commissioning Experience with the PEP-II Low-Level RF System*
The low-level RF system for PEP-II is a modular design housed in a VXI environment and supported by EPICS. All signal processing and control is done at baseband using in-phase and quadrature (IQ) techniques. Remotely configurable RF feedback loops are used to control coupled-bunch instabilities driven by the accelerating mode of the RF cavities. A programmable DSP based feedback loop is impleme...

Our primary role in the genesis of PEP-II, the energy-asymmetric B-meson factory at the Stanford Linear Accelerator Center, has since evolved into a major collaborative construction project. The project, when completed, will greatly facilitate the study of CP violation. Our scientists and engineers remain involved with PEP-II, especially in beam dynamics studies and in rf and feedback systems. ...
متن کاملThe PEP-II Project: Low-Energy Ring Design and Project Status
We describe the present status of the PEP-II project. The project comprises four major systems: Injector, High-Energy Ring (HER), Low-Energy Ring (LER), and Interaction Region (IR). We focus in detail on the design of the LER, as its parameters and requirements are most closely related to those required for the Beijing Tau-Charm Factory rings. The PEP-II LER is a high-current, 3.1-GeV positron ...

The growth rates of the longitudinal higher-order impedance-driven beam modes have greatly increased since the initial PEP-II design and commissioning. This increase is attributed to the addition of 6 1.2MW RF stations with 8 accelerating cavities in the HER and 2 1.2MW RF stations with 4 accelerating cavities in the LER, which allowed operations at twice the design current and almost four time...
متن کاملArchitecture and Performance of the PEP-II Low-Level RF System*
Heavy beam loading in the PEP-II B Factory along with large ring circumferences places unique requirements upon the low-level RF (LLRF) system. RF feedback loops must reduce the impedance observed by the beam while ignoring the cavity transients caused by the ion clearing gap. Special attention must be placed on the cavity tuner loops to allow matching the ion clearing gap transients in the hig...
